Lithium-Ion Batteries Testing

Lithium-Ion Batteries

Lithium-ion batteries power the lives of millions of people each day. From laptops and cell phones to hybrids and electric cars, this powerful technology is growing in popularity due to its light weight, high energy density, and ability to recharge.

The lithium-ion battery is the most popular commercial form of rechargeable battery, widely used in portable electronics and electrified transportation.

Compared to other high-quality rechargeable battery technologies Lithium-ion batteries have some of the highest energy densities of any commercial battery technology, which also makes them suitable for high-power applications like transportation.

Lithium-ion batteries are comparatively low maintenance, and do not require scheduled cycling to maintain their battery life. Lithium-ion batteries also have a low self-discharge rate of around 1.5–2% per month, and do not contain toxic lead or cadmium.

High energy densities and long lifespans have made Li-ion batteries the market leader in portable electronic devices and electrified transportation.

Lithium-Ion Batteries Testing

Lithium-ion battery testing involves a series of procedures conducted to evaluate the performance, safety, and lifespan of lithium-ion batteries.

Battery testing typically involves the use of specialized equipment and software, to simulate real-world conditions and measure various parameters such as capacity, voltage, temperature, and resistance.

These tests may be performed on individual cells, modules, or complete battery packs.

Safety is a primary concern with these batteries, as they have the potential to overheat, catch fire, or even explode under certain conditions.

To ensure the safety of lithium-ion batteries, various standards and certifications have been developed. These standards and certifications provide guidelines and requirements for the design, testing, and use of lithium-ion batteries, as well as for their transportation and disposal.

All lithium-ion batteries are required to undergo testing prior to shipping. These tests subject batteries and cells to conditions they would experience during shipping and handling. Typical conditions will include extreme temperature conditions, shock, impact and short circuit testing to ensure the stability of batteries and cells.

Battery charger testing takes into account the risks and safety hazards associated with AC powered devices which contain lithium-ion batteries. This includes testing for the potential for overheating and electric shock from the device.

Some of the most widely recognized safety standards and certifications for lithium-ion batteries include UN 38.3 which specifies the testing requirements for the safe transportation of lithium-ion batteries, including the need for a vibration, shock, and thermal test.

IEC 62133 which sets the safety requirements for secondary (rechargeable) lithium-ion batteries for use in portable applications.

UL 1642 specifies the requirements for the safety of lithium-ion cells, whilst UL 2054 covers the safety of lithium-ion battery packs.

CE marking and certification indicates compliance with European Union safety, health, and environmental protection standards. Lithium-ion batteries which are sold in the European Union must bear the CE marking.

RoHS is the Restriction of Hazardous Substances Directive, a regulation that restricts the use of certain hazardous materials in electrical and electronic equipment. Lithium-ion batteries sold in the European Union must comply with RoHS.

Good News - June 8-14

Like these weekly compilations? Tip me at $Kaybarr1735! And if you tip me and give me a way to contact you, at the end of the month I'll send you a link to all of the articles I found but didn't use each week!

1. Rare foal born on estate for first time in 100 years

“The Food Museum at Abbot's Hall in Stowmarket, Suffolk, is home to a small number of Suffolk Punch horses - a breed considered critically endangered by the Rare Breeds Survival Trust. A female foal was born on Saturday and has been named Abbots Juno to honour the last horse born at the museum in 1924. [...] Juno is just one of 12 fillies born so far this year in the country and she could potentially help produce more of the breed in the future.”

2. The cement that could turn your house into a giant battery

“[Scientists] at Massachusetts Institute of Technology (MIT) have found a way of creating an energy storage device known as a supercapacitor from three basic, cheap materials – water, cement and a soot-like substance called carbon black. [... Supercapacitators] can charge much more quickly than a lithium ion battery and don't suffer from the same levels of degradation in performance. [... Future applications of this concrete might include] roads that store solar energy and then release it to recharge electric cars wirelessly as they drive along a road [... and] energy-storing foundations of houses.”

3. New road lights, fewer dead insects—insect-friendly lighting successfully tested

“Tailored and shielded road lights make the light source almost invisible outside the illuminated area and significantly reduces the lethal attraction for flying insects in different environments. [...] The new LED luminaires deliver more focused light, reduce spill light, and are shielded above and to the side to minimize light pollution. [... In contrast,] dimming the conventional lights by a factor of 5 had no significant effect on insect attraction.”

4. When LGBTQ health is at stake, patient navigators are ready to help

“[S]ome health care systems have begun to offer guides, or navigators, to get people the help they need. [... W]hether they're just looking for a new doctor or taking the first step toward getting gender-affirming care, "a lot of our patients really benefit from having someone like me who is there to make sure that they are getting connected with a person who is immediately going to provide a safe environment for them." [... A navigator] also connects people with LGBTQ community organizations, social groups and peer support groups.”

5. Tech company to help tackle invasive plant species

“Himalayan balsam has very sugary nectar which tempts bees and other pollinators away from native plants, thereby preventing them from producing seed. It outcompetes native plant species for resources such as sunlight, space and nutrients. [...] The volunteer scheme is open to all GWT WilderGlos users who have a smartphone and can download the Crowdorsa app, where they can then earn up to 25p per square meter of Balsam removed.”

6. [Fish & Wildlife] Service Provides Over $14 Million to Benefit Local Communities, Clean Waterways and Recreational Boaters

“The U.S. Fish and Wildlife Service is distributing more than $14 million in Clean Vessel Act grants to improve water quality and increase opportunities for fishing, shellfish harvests and safe swimming in the nation’s waterways. By helping recreational boaters properly dispose of sewage, this year’s grants will improve conditions for local communities, wildlife and recreational boaters in 18 states and Guam.”

7. Bornean clouded leopard family filmed in wild for first time ever

“Camera traps in Tanjung Puting National Park in Indonesian Borneo have captured a Bornean clouded leopard mother and her two cubs wandering through a forest. It's the first time a family of these endangered leopards has been caught on camera in the wild, according [to] staff from the Orangutan Foundation who placed camera traps throughout the forest to learn more about the elusive species.”

8. Toy library helps parents save money 'and the planet'

“Started in 2015 by Annie Berry, South Bristol's toy library aims to reduce waste and allow more children access to more - and sometimes expensive - toys. [...] Ms Berry partnered with the St Philips recycling centre on a pilot project to rescue items back from landfill, bringing more toys into the library. [...] [P]eople use it to support the environment, take out toys that they might not have the space for at home or be able to afford, and allow children to pick non-gender specific toys.”

9. Chicago Receives $3M Grant to Inventory Its Trees and Create Plan to Manage City’s Urban Forest

“The Chicago Park District received a $1.48 million grant [“made available through the federal Inflation Reduction Act”] to complete a 100% inventory of its estimated 250,000 trees, develop an urban forestry management plan and plant 200 trees in disadvantaged areas with the highest need. As with the city, development of the management plan is expected to involve significant community input.”

10. Strong Public Support for Indigenous Co-Stewardship Plan for Bears Ears National Monument

“[The NFW has a] plan to collaboratively steward Bears Ears National Monument to safeguard wildlife, protect cultural resources, and better manage outdoor recreation. The plan was the result of a two-year collaboration among the five Tribes of the Bears Ears Inter-Tribal Coalition and upholds Tribal sovereignty, incorporates Traditional Ecological Knowledge, and responsibly manages the monument for hunting, fishing, and other outdoor recreation while ensuring the continued health of the ecosystem.”

ok ramble, sparked by this:

i really recommend you guys go about looking up what components would have been hit and also how much of a fucking struggle me/ipad repair is. im no tech expert but its pretty difficult and even in the fantastical setting of ii it would NOT be easy and it does get to the point where Test Tube would be replacing a lot if important components.

1*, 2-4**

*yeah its a simplified kids lesson but its a nifty diagram

** an interesting read on the reparability of the 1st gen iPad

even if Cobs missed all of Mepads important shit (miraculously), it would still be stabbing a lithium ion polymer battery which uh.

yeah. its not looking good for dear sweet precious Mepad </3

DISCLAIMER: im not hating on the "Mepad gets fixed up fine by TT" scenario. i like it. go read this if you also like it, its a good fanfic. nor am i hating on the OP of the screenshot, i just think that theyre disregarding several facts of damage to dunk on a perfectly fine scenario and i dont get that. our beautiful Mepad idea nations should be living in harmony bc both ideas have fun opportunities within them 🤝 lets all be nice to eachother and not be disparaging about others ideas

F1's DC/AC: Assault & Battery

Formula 1 teams source batteries for their power units, specifically the Energy Store (ES) component, from specialized manufacturers and in-house development, driven by the sport’s stringent performance and safety requirements. The disposal of used batteries follows strict regulations to ensure environmental responsibility, given their hazardous materials. Below is a detailed breakdown:

Sourcing of Batteries for Formula 1 Power Units

Specialized Battery Manufacturers:

Companies like Saft, a leader in high-performance batteries, have historically supplied F1 teams with lithium-ion batteries for the Energy Recovery System (ERS). Saft’s experience, including work on defense projects like the Lockheed Martin F-35, has been adapted for F1’s extreme conditions.

About:Energy, a battery testing and software specialist, collaborates with F1 teams to develop and optimize battery performance through simulation and testing, focusing on power density and degradation.

Other suppliers, such as Marelli, provide components like the Motor Generator Unit (MGU) and associated battery systems, tailoring designs to team specifications.

In-House Development by Power Unit Manufacturers:

Major power unit suppliers—Mercedes, Ferrari, Honda, Audi, and Red Bull Powertrains (with Ford)—often develop batteries in-house or in close partnership with specialists. For example:

Mercedes High Performance Powertrains (HPP) in Brixworth, UK, integrates battery development into its power unit program, leveraging expertise from the turbo-hybrid era.

Ferrari designs its own batteries in Maranello, aligning with its power unit strategy to supply its factory team and customers like Haas and Cadillac.

Honda has advanced lightweight battery designs, achieving significant weight reductions (up to 5kg) for performance gains.

These manufacturers work with advanced lithium-ion chemistries, optimizing for high power density (up to 350kW in 2026 regulations) and energy recovery (up to 9MJ per lap).

Collaborative Innovation:

Teams and suppliers push boundaries in battery chemistry and design, exploring formats like cylindrical, pouch, or prismatic cells to balance energy density, weight (20-25kg regulatory limit), and packaging within the chassis.

Emerging technologies, such as solid-state batteries, are under consideration for future F1 applications, offering potential improvements in lifetime and energy density.

Partnerships with academic institutions, like Imperial College London, aid in refining battery performance for motorsport.

Regulatory Compliance:

Batteries must meet FIA safety standards, including UN38.3 for lithium-ion transport and crash test requirements to prevent dangerous reactions. These regulations influence sourcing decisions, as only certified suppliers can meet such demands.

The FIA’s 2026 regulations, emphasizing a 50/50 power split between internal combustion and electric systems, have spurred investment in battery development, attracting new manufacturers like Audi and Ford.

Disposal of Used Batteries

Regulatory Limits on Battery Usage:

FIA rules limit teams to a set number of Energy Stores per season (currently four, reducing to two in future seasons) to control costs and environmental impact. Exceeding this incurs grid penalties, incentivizing durable designs.

Batteries are designed to withstand intense charge-discharge cycles (10-15 per lap, depending on the circuit), but degradation over a season necessitates replacement.

Recycling and Disposal Processes:

Hazardous Material Handling: Lithium-ion batteries contain chemicals that pose environmental risks if mishandled. F1 teams, operating under EU and international regulations, partner with certified recycling facilities to manage disposal. The EU Battery Directive (2006/66/EC) mandates recycling to recover materials like lithium, cobalt, and nickel.

Specialized Recycling Partners: Companies like Umicore and Redwood Materials (common in automotive sectors) recycle lithium-ion batteries, extracting valuable metals for reuse in new batteries or other applications. While F1-specific partnerships are not publicly detailed, teams likely use similar services given the high-value materials involved.

Closed-Loop Systems: Some manufacturers, like Saft, integrate recycling into their supply chains, repurposing materials from used batteries to reduce waste and costs. This aligns with F1’s push for sustainability, including 100% sustainable fuels by 2026.

Repurposing: Degraded F1 batteries, which no longer meet the sport’s performance demands, may be repurposed for less demanding applications, such as energy storage systems or testing rigs, before final recycling. This practice is common in motorsport and automotive industries.

Environmental Considerations:

The FIA and F1 emphasize sustainability, with initiatives like sustainable fuels and increased hybrid efficiency reducing the sport’s carbon footprint. Battery disposal is part of this, with teams required to adhere to strict environmental protocols.

The high energy density and specialized chemistry of F1 batteries (100-275Wh/kg) make recycling complex but critical to avoid landfill waste and comply with regulations.

Challenges and Innovations:

The 2026 regulations, increasing battery power to 350kW and energy recovery to 9MJ per lap, will intensify battery wear, raising disposal frequency. Teams are exploring chemistries that minimize degradation to extend battery life and reduce waste.

Research into fast-charging and durable batteries aims to lower the environmental impact by reducing the need for oversized batteries, which add weight and disposal burdens.

Critical Notes

Limited Public Data: Exact suppliers and disposal partners for each team are closely guarded due to F1’s competitive nature. Information is often proprietary, with teams like Ferrari and Mercedes only broadly acknowledging in-house or specialist involvement.

Sustainability Push: F1’s commitment to net-zero by 2030 drives innovation in battery recycling and sustainable sourcing, but the sport’s high-performance demands create unique challenges compared to road-car battery systems.

Speculative Future: Solid-state batteries or alternative chemistries could reduce disposal issues by offering longer lifespans, but these are not yet standard in F1.

In summary, F1 teams source batteries from elite suppliers like Saft and through in-house programs at manufacturers like Mercedes and Ferrari, focusing on cutting-edge lithium-ion technology. Used batteries are recycled through specialized facilities to recover materials, aligning with environmental regulations and F1’s sustainability goals. The lack of specific team-by-team disposal data reflects the sport’s secrecy, but industry-standard practices provide a reliable framework.

So how's YOUR week going, Angie?

I started a new job, at a warehouse that is a huge local employer. I'd worked there before, and it had been DISMAL, but I heard that things had improved there and I needed some dough so I reapplied.

NOPE.

Orientation was Friday morning, and by Friday night I had emailed HR expressing my concerns. Our OSHA trainer, between weird complaints about "wokeness" and the Second Amendment, had skipped over some government-mandated safety training. Among these, and the one I was most concerned by, was the Hazmat training. Said training was just a one-page multiple choice test, which he handed us and then gave us the answers to. "Number three, A. Number four, D. Number five, false... Okay, now sign them and hand them back." When I said that I'd like to actually READ the test at the very least, he started using me as an example to the rest of the orientation class that "I'd better not see you making fun of people who can't read!"

You know that advice you read online where you should follow up and document EVERY interaction with managers and HR on email, to cover your butt when things go wrong? Yep.

By Wednesday, I had an email chain with HR recorded, including the details of an HR rep telling me that I would never ACTUALLY be exposed to hazardous materials on my floor, so that mandatory training wasn't going to be a big deal anyway, so no worries.

My floor dealt with alcohol-based perfumes, aerosol hairsprays, aerosol insecticides, and portable phone chargers with lithium-ion batteries. All of these have to be packed in specific ways for shipment or they're a huge safety hazard to everyone in range, and they are NOT getting packed in those ways. I know, because I managed to get a photo on my phone of said dangerous packing, and it's not the warehouse packers' faults because if they went through the same orientation I did, THEY WERE NEVER TOLD NOT TO DO THIS.

Anyway, I just learned that there's a government OSHA office less than 45 minutes away from my house. Guess who I'm taking this email chain and photograph to next Monday!

It’s actually crazy that Honda and Nissan are discussing merging because of how much they’re struggling in the EV market, when both of them were once at the forefront of the EV market.

They had the automotive market in their hands… but they listed to the Oil Industry’s dollars a little too hard, and look where it’s gotten them.

After learning from the limited-run, lease-only 1997 Honda EV Plus, in 1999 Honda released the first hybrid vehicle on American roads, the Honda Insight. That car still, today, holds the record for the most efficient internal combustion engine vehicle that the EPA has ever tested.

After the limited-run, lease-only 1997 Nissan Altra debuted, it became the first electric vehicle to utilize Lithium Ion batteries, a technology that makes the EV industry possible, these days. What Nissan learned from that compliance car is what allowed them to build the 2010 Nissan LEAF: The world’s first purchasable, affordably priced, AND mass produced electric passenger car with legacy automaker parts and dealership support. It was revolutionary, and it shocked a lot of the auto world, who didn’t think it was possible.

Then… they just gave up. They had unimaginable success in their hands, and then… they decided to shuffle their feet, and now here they are.

DRAtchet week 2022 Day 6: Indiscreet Photo.

(First Day)||(Day 5)||(Day 7)||(Last Day)

In which Deadlock's and Ratchet's relationship is told in snapshots but maybe they should see who behind the camera.

After all of that fighting done that night, Deadlock managed to keep Ratchet. More than that he finally, finally has Ratchet's permission to enter his home. They actually started to move in together. Even though Ratchet's house has no furnishings or even a bed, this is pure bliss.

So the first thing he moves over to the house is the bed. Not because Deadlock can't handle the floor but because Ratchet is going to have recover for the next few weeks. They found a chop shop that could fix up almost all of the damage from the muggings. Everything except his hands.

All of the technical aspects go over his head, but the jest of it is that the wiring will mimic the exoskeleton. However it will always be five nanoseconds delayed. It wasn't much and to a normal mech the difference wasn't even noticeable, but Ratchet. Ratchet notices instantly, he ran five simple tests and picked up on how much slower his new hand is.

He's grateful, none of the mechanics think he isn't. However, Ratchet asks if they could just allow him to repair his shattered hands. So coming home every night he sees Ratchet sitting down on the bed, trying to navigate fixing it.

Deadlock can really see how much those five nanoseconds matters. How much slower and sloppy his work is. Before he used to be as gentle as snow, but now he can barely hold his hand in the air.

He is proud of Ratchet, the mech might have been ready to give up on them, but he was always determined to healing. It will take a lot of work and practice to get him back in tip top shape, but Deadlock knows that if anyone could rebound it's him.

Last night Ratchet made a big break through. He got two of the fingers to work, they're still unreliable, certainly not ready for any kind of work. However, Deadlock believes this is a good enough reason to celebrate. "Trust me. This place has really good Electric Indium Rocks."

"But what if I don't like Electric treats." Ratchet hooks his new working arm his and rest his head against his chest as they walk down the street. A date, a real and honest date. While the first time at the club was nice, this one is honest.

"You can order something else. I'll just eat what you don't want." Deadlock opens the door to the and leads Ratchet to sit at the table on the back wall. Walking away to set their order was harder than he expected it to be. The Ratchet shaped cold spot makes the distance worse but it isn't long before he goes back.

Sitting to make sure that any bad actors would have to get through him before they could touch Ratchet. "There's an open seat over right there." Ratchet makes a pointed look at the sad looking barstool across from them.

"Yeah?" He laughs it off. No point in letting Ratchet convince him to switch seats. "Well since you said that you don't like Electric so I got some Lithium Ion and Battery Ooze." Placing the bag that the assistant gave him all of the treats scatter on the table.

"That looks like more than those two." Ratchet picks up the round one that is rolling towards the edge of the table. Eating the whole thing in one go, shaking his head from the strong sour taste.

"Maybe you should let me pick them." He shouldn't be laughing, it's not very romantic, but-

"I think you've done enough choosing." Ratchet moves to take the one Deadlock was starting at. Holding it up to his lips, shaking it back and forth, but his hand freezes up, dropping it. He stays still, not one word. Keeping his hand in the same position, shame seeping out of his field.

"Here." Deadlock picks up one of the cooper nuggets and feeds it to him. He can feel his chapped lips, his warmth breath, and soft gaze. "I think you'll like this one better."

That's how they spent the night. Deadlock picking up whatever snack he deemed tasty and feeding it to him. Watching the flickering of emotion as different flavors cross his tongue. The way his thoat works and the ever growing fuel filling him up. It states a more primal instinct and knowing that it was he who fills his lover. Well it's a good thing that he moded his panels to stay lockdown until he turns the code off.

"I shouldn't have eaten so much." Ratchet puts his fist in front of his mouth to keep to fuel in. "I don't think I can drive let alone walk back." Primus he is cute enough to eat.

"I don't know..." Deadlock let's his engine purr. "You can afford to eat more." He rubs Ratchet's plating. "I don't mind carrying you home."

Ratchet gives him that cute little pout. "With your weak ankles, ya right."

"The two of you were very cute. Right Deadlock?" Was the caption on the photo.

---

More time passes and Ratchet has fixed enough of his hand that all fingers are moving. He still has trouble holding things and they start to shake if they stay up for to long. It was a huge improvement, but more than that it gave Ratchet back his confidence. He even had gain that sassy sawy when he walks. The air of authority comes back to full force as he goes back to repairing mechs off the streets.

Tonight, the two of them are heading back to the shop. As Ratchet's has to go through one more exam before they clear him for duty. Bracing himself as the enter the shop, the deep smell of blood never truly goes away. "Well wer here." He bangs on the chains hanging on the wall.

"Cool your thrusters." A saw blades starts spinning, "We'll be ready in a bit." Another spark lights the corner of the room and he swears he can hear someone screaming in pain.

"Have a seat." Ratchet took his hands and drags Deadlock to the seat next to him. "We can make out while we wait."

"Huh?" He turns to face him only to get a sight full of Ratchet's smile, was he teasing him.

"Oh no you don't." The red sports car comes from the other side of the room. His paint is always emasculate, and at first Deadlock didn't trust him to be an actual doctor. "If Breakdown and I can't make out at work than neither can you." He makes his way towards Ratchet, bending down to hold up his hand and running scans. If Deadlock is jealous only Ratchet notices as he just sends him a smug look.

"What's the diagnosis, Knockout?"

"Good." He flips the hand over and starts testing his sensitivity. "In fact you fixed this to almost match the original specs. Practically made a miracle." Deadlock puts his hand on his thighs to express his pride. "Impressive."

"Let me see." Breakdown comes from upstairs and joins the three of them. "Yeah." He takes the hand from Knockout and gives it a stress test. "You may need a bit more time for all of the sensors to work but yeah great work."

"Choppshop." Knockout whistles for the owner to come over. A big mech or rather a group of mini insecticons that form the hulking mech. His two sets of eyes stare deeply into Ratchet's hand as the silicone hairs press against it. "So?"

"He'd save us a lot on supplies, and I ain't got time to reformat alloy."

"What's going on?" Deadlock takes a look at Ratchet. The exchange between him and the rest of the crew is suspicious.

"I ment to tell you." Ratchet moves to run his fingers down his thighs, comforting him. "I was thinking about joining the shop." He looks down keeping gaze away from his. "You know- to help others." It wasn't him asking permission, at least not yo Deadlock. More like he was asking Choppshop to join and is telling him as a formality.

"I get it Ratch." He links their hands together.

"Then let's update the staff picture." Breakdown pulls out a camera hands it over to Deadlock and pushes him out. The rest of the mechs pose themselves around Ratchet. Look at him with a knowing smile as they wait for him to take the photo.

"Say Gasoline."

"This is the place your Ratchet works, correct?" The caption of this group photo reads.

----

Another long, painful shift, Deadlock and the rest of the stunt crew get a half jorn break to refuel and stretch out their legs. Today has been especially tough since two of the main actors switched acts and now they have to start training all over again.

Another dent fender and a twist bumper. He is one of the lucky ones as the guy next to him as a burnt interior filters, with his tire sticking out of his chassis. The other bot in front of him has it worst as he caught the preform in root mode. His axel is twisted and his hip dislocation, he won't be able to transform until that gets fixed.

There's suddenly the crowd starts to whisper, commenting on a new vehicle that is headed this way. In fact it looks a lot like-

"Hey Drift." The mech behind him shoves his shoulder to grab his attention. "You see that bot? The alt mode looks kinda cute no?"

He doesn't get a chance to reply as said vehicle transforms in front of them. To his surprise Ratchet is here and Deadlock realizes that this is the first time he's ever seen his alt mode. It was another shock that he really was not an ambulance. "What are you doin here?"

"I had some extra time." Ratchet then pulls out a crate wrapped up in organic fabric. It was red, with gold hearts, clearly Knockout's but cute. "I figured we could have lunch together." He turns his face away from him, and Primus is he blushing. "To be honest," Ratchet keeps his head away but his eyes come back to look at him. "Breakdown suggested this, and I didn't have anything better."

Maybe it was the heat of the day, or the bruise of his battle scar, but Deadlock can feel his vents kick into high gear. "Yeah." Oh that was the wrong thing as the bot he was talking to face palms. "Here." He takes Ratchet's hands and tries to guide him to sit down on the floor next to him. That was until his bumper starts acting up and tumbles onto the ground hard.

"What happened?" Ratchet drops down to examine the situation. Putting both hands on eithet side of his shoulder to turn him over. The light of the sun makes a ring around his head, like straight out of a dream. That is palling in comparison to the genuine concern in his eyes as he waits for a response.

"Just my fender acting up." He manages to sit normally. Ratchet rushes to his side, he wraps himself around him. Deadlock closes his eyes and waits for the gentle touch. So it's a hard wake up when Ratchet digs into where his vehicle front is stored. He yanks out his fender and with his two hands untwists it. "Ouch." He tries to hold back a yell.

"Sorry." Ratchet gives him a hug, rubbing his face on his chest and planting a kiss.

A whistle brakes the moment. "What's a mech got to do to earn something like that?" Deadlock's coworker says as he continues to watch the two of them. When he coughs and the smoke from the wreckage comes out of his mouth, Ratchet is pulling away.

"What's wrong with you?"

"You tell me." The bot stands up and the rubber from the tire sticks out. No other words is said as Ratchet makes his way to the mech and starts to get to work. Unfortunately, more of the crew came to get repairs. It ate into their lunch, and by the time Ratchet was finished the sun went down and most of the circus left.

"I'm sorry Deadlock." Ratchet gives him another hug.

"It's alright. I got a nice view of you at work." A blush creep up on his face and Primus he was so cute. Cute enough to eat, and he would have if he doesn't have work tomorrow.

"Hey you two." The both of them both follow the voice that calls for them. When they both tracked it the a mech with a camera took their picture. "Here." He sent the image forward. "I figured that I should give you something as thanks." He raised his arm and bent it to show it was fixed now.

"Hmph." Ratchet steps away from him. "Just don't do anything reckless. I don't want to come back to fix it."

We wouldn't want the Ring Leader to know that his new medic is swapping paint with the Decepticon's most prominent weapon. Right?

-----

"So... Deadlock." Ratchet stands at the front of the door, ready to head out for work. They haven't had much time together, this had been the only day in the last few months. "I've been giving it a lot of thought." He lifts his head to look at him but his eyes shift elsewhere. "And maybe it's too early for you but. We should move in together."

Those words ring loudly in his head. It shouldn't matter much, the two of them sleep together here on their off days. While yeah, it wasn't often, it was just enough that Ratchet trust him to rest next to him. The idea to have him everyday, to hold him, to be able to watch him fall asleep and wake up to him. "Uhh yeah." He answers so eloquently. "I'll get all my stuff ready to your place by next week."

Ratchet gives him the most beautiful, genuine smile ever. The world turns perfectly and the sun shines ever brighter. "Okay. I'll get the house ready for you. Tomorrow I'll give you the passcode and a key."

The times the photo has no caption. It's just a grainy picture of Ratchet opening the door to their appartment. A letter behind it has today's date, a list of mechs and the bounty amount. It has no signature, no contact information. The photos were a clear sign that they have ways of tracking him down. More important, they were threatening Ratchet and once he gets out of this mess he will deal with them.

"I'll do it." Deadlock looks at the two goons in front of him. He left his blasters at home and they don't hand theirs over. "But then you already knew that." If he wasn't tied up in the chair he was sitting in he would have attacked them.

It was the first sign that his weakness would put Ratchet in danger. The beginning of the end.

Lithium-Ion Batteries Certification

Because of the enhanced performance of lithium-ion batteries, their popularity has grown exponentially in recent years.

Their use has contributed to the proliferation of portable consumer electronics, laptop computers, cellular phones, and electric cars

In order to achieve the approvals required for their increased use, lithium-ion batteries Certification are subject to a rigorous testing regime, assessing the performance, safety and life of lithium-ion batteries.

Safety and reliability are of the utmost importance, and the International Electrotechnical Commission (IEC) has established the key safety testing and certification of lithium-ion batteries. This provides manufacturers, regulators, and consumers with the confidence that these batteries meet the highest of standards.

IEC certification is obtained through accredited battery and electrical testing laboratories, which ensure any battery passes the required tests, and meets all the required safety criteria. The IEC certification provides approval that lithium-ion batteries are safe for use in electronic devices and compliant with international safety standards.

Because of the safety implications of transporting and disposal of batteries, the United Nations has issued testing and approval certification for a number of typical scenarios.

Thermal, vibration, shock, impact and overcharge are all amongst the tests that can be undertaken and certified under UN regulation 38.3. This ensures the safety and transportation of lithium-ion batteries is maintained to the highest international standards.

Material Safety Data Sheets provide certification which is internationally recognized, and ensures that safety regulations and guidelines are met and maintained. Safety data sheets refer to battery shape, size, makeup and voltage, including stability and reactivity, and toxicological information.

This data certification enables transportation without which shipping or transportation will not be possible.

Additional testing and certification of lithium-ion batteries is provided by Underwriter Laboratories. Supported by a world-wide network of locations, Underwriter Laboratories specify comprehensive technical details in terms of battery safety and applications.

Because of the increasing attention to the safety standards of lithium-ion batteries, in addition to the recognized worldwide certifications, local certification has become a feature of the regulatory nature that exists.

Norway has released a Circular Series V which supervises and approves lithium-ion technology in the maritime transport sector.

Japanese PSE regulations and certification have been established as a mandatory benchmark, to ensure products, including lithium-ion batteries meet the stringent requirements for entry to Japanese markets.

As the focus on safety and performance of lithium-ion batteries remains a key issue, the standard and frequency of approvals and certification will continue to feature in the use and incorporation of lithium-ion batteries.
