防火安全
如果您的设备感觉非常热,或闻起来很难闻,请勿尝试取出电池。如果您的设备正在积极冒烟,请清除周围区域。
如果您无法移动设备,可以用沙子,经认可的灭火器熄灭火灾,配合使用一大杯水,或用防火容器盖住,站远一点。 如果你可以安全地移动设备,请将其放在防火或通风良好的区域,例如混凝土地板 - 然后保持清洁,直到电池冷却。一旦电池着火,反应将持续直到燃料耗尽。
警告
鼓包膨胀的锂电池可能会发生火灾或爆炸。从电子设备中取出鼓包的锂电池时,请特别注意并承担自己的风险。如果您有任何疑虑,您可以安全地执行,关闭电源并隔离设备,并立即咨询专业维修技师。
移除膨胀的电池可能是危险的,但在设备内部留下膨胀的电池也会带来风险。为防止潜在的设备和人身伤害,设备不应使用膨胀的电池。这些指南提供了去除肿胀电池的最佳操作方式,但不能保证安全修复。如果您有疑问,请关闭设备电源,将其放入防火容器中,然后带到维修专业人员,要求他们拆除故障电池。不要延迟电池拆卸。如果您的电池是从iFixit购买的,请在取出之前和之后拍摄电池照片,然后contact our customer service team进行保修索赔或更换。
当电池鼓包时会发生什么?
锂离子电池使用化学反应来发电。随着电池老化,这种化学反应不再完美地完成,这可能导致产生气体(称为放气),导致电池膨胀鼓包。此外,如果电池的化学品层不能保持适当的分离(由于损坏或缺陷),可能会发生放气,膨胀甚至火灾。膨胀是颗粒被夹在电池层之间并最终刺穿分离层隔膜的结果。如果隔膜受损,空气中的水分会与电池单元反应,导致电池单元鼓包。这种爆炸性反应已经臭名昭著地影响了Samsung Galaxy Note7和hoverboards,导致对运输电池的严格限制,以及在飞机上携带它们。
如何识别鼓包的电池
检查设备
随着电池膨胀,它们会膨胀并推开其他组件。通常情况下,显示器,按钮或触控板将被推出正常的对齐状态。如果您的手机外壳不再像以前那样完好的对齐,或者组件之间存在新的间隙,亦或者按钮变得僵硬或难以推动,以及您觉得您设备的外壳开始出现弹性变形,并伴随着不正常的“挤压感”。
通过气味识别
练习安全的嗅探测试!切勿将危险物质粘在脸上并深深地吸气 - waft电池附近的区域。你可能会注意到一种甜美的金属化学气味,这种气味可能是电池气体从一个膨胀的电池中逸出。
检查电池
如果您的设备易于打开而不会影响电池(请查看电池更换指南以查看),比如MacBook或iPhone,您可以打开设备并目视检查电池是否浮肿。如果电池的包裹松散或皱褶,比方形更圆,或者从凹槽中抬起,就已经鼓包膨胀了。
如何安全地移除肿胀的电池
开始之前
如果你怀疑你的电池是否肿胀,请不要给你的设备充电。尽可能地运行耗尽电池电量,这样可以降低火灾的风险。
保护自己
在通风良好的区域工作,以帮助烟雾飘散。戴上护目镜 - 理想的是全护目镜,但安全眼镜总比没有好。戴上手套以防止皮肤接触电池化学品。有一对长而钝的钳子可以帮助安全地移动损坏的电池。
准备你的环境
如果电池开始燃烧或泄漏,您需要有一个安全的地方来存放它。请在非易燃表面,或凉爽且干燥的室外进行电池更换操作。准备一个防火容器,如密封的金属罐,金属桶沙或等同物。 在任何情况下都不要使用水,因为锂会与水发生反应并导致火灾。如果你在室内进行操作,请确保你能随时前往电池能够安全反应完毕的地点(如果发生泄漏)。
取出电池
完成上述预防措施后,即可开始取出电池。在大多数情况下,您可以按照设备的电池更换指南进行操作,但你仍应特别注意避免在拆卸过程中损坏电池。如果电池粘的很牢固,我们建议使用iFixit的粘合剂去除剂,高浓度异丙醇或丙酮等溶剂。溶剂可最大限度地减少撬动或弯曲电池的需要。请记住,丙酮可能会损坏塑料部件,所有溶剂应尽可能少地使用 - 它们易燃。只使用塑料工具,并避免任何尖锐的东西刺破电池包裹 - 刺破电池可能导致危险的火灾。如果在任何时候气味增加,设备开始升温,或出现任何烟雾,将设备放在室外或放在防火容器中,等待症状消失再重新尝试。
如何处理鼓包的电池
取出电池后,需要安全处理。 不要将电池扔进垃圾桶或回收箱。不要将电池放入/存放在水中。如果电池发热,有异味或冒烟,请将其放在远离易燃材料的地方或防火容器内,并等待症状消散。安全时,将电池带到当地的电子废物收集站点,请参阅我们的 e-waste page,找到您所在地区的站点。不要将电池邮寄到电子废物处理设施 - 对此有严格的规定,因为电池可能会在运输过程中造成损坏。
所有电池都是危险废物
处理电池需要特别注意。在任何情况下,所有电池都存在着火和安全隐患,应妥善处理和处理。电池不能放入城市垃圾收集中,必须带到危险废物收集设施。通过Earth911或互联网搜索查找危险废物收集设施。
如何照顾你的电池
电池是消耗品,无论你如何妥善地保养它们,它们最终都需要更换。也就是说,以下是一些尽可能保持电池健康的最佳做法。但是,重要的是要注意你不能修好鼓包或有缺陷的电池,你只能处理掉它。这些提示只能帮助“防止”电池老化。
通过缓慢,可控的充电和放电,在合适的温度下使用,以及防止冲击或损坏,可以使电池达到最佳的效能。尽管很人的多笔记本和手机的电池都没有定期进行完全充放电循环,但短时间内快速地充电和放电会对电池造成永久性损伤并阻碍其化学反应正常完成,从而导致电池放气鼓包。使用未经认证的充电电缆或适配器可能会导致不受控制,不均匀或过度地充电。而且过度的电池保养一样会损坏电池甚至引起火灾。电池长期处于满电(100%)或完全放电(0%)的状态一样会缩短电池寿命,如果你打算长期存放你的设备,请将其电量充至/用至40%左右再进行储存。高温也会降低电池效率,所以尽量不要在炎热的天气将手机放在车内。同样最重要的是,摔落摔落时的碰撞也会损坏电池,而不仅仅是屏幕。就像汽车一样,手机在发生事故时也会弯曲,所以即使是胶合电池也会在掉落时碰到附近的部件,导致穿刺。如果电池损坏或不再正常的充放电,请更换电池。
太长不看省流版:对你的电池好一点,恰当地使用,如果你觉得它无法正常充电或者破损时立即更换它。

Leaving your device plugged in forces it to drain and charge many times an hour, which can degrade the battery - this is rubbish. If the device is plugged in the battery will usually end up fully charged - which is not ideal as about 40% charge is best for battery longevity - but it won’t drain and charge continually. Instead, once the battery is fully charged it is essentially removed from the circuit and the charger powers the device.
Using a non-certified charging cable or adapter risks uncontrolled, uneven, or excessive charging that can cause damage or even result in fire - this is not quite true. All devices contain a charge controller that prevents overcharging regardless of the charger used. However, cheap chargers may subject you to the risk of electrocution, may produce ‘noisy’ DC that reduces the performance of the touchscreen, or may themselves catch fire. A damaged charger cable can also overheat and cause a fire.

Depends on the design of the charging circuitry. While your statement of “battery being decoupled if fully charged” might be true on some devices, the usual (because simpler to design and cheaper due to less parts) approach is to power the device through the battery. Even if a charger is connected.

daniel1 lungu -
This is not true for mobile phones - my understanding is that they run off the battery regardless of whether they’re plugged into a charger or not.
The reason for this is that the battery is capable of delivered much greater transient current than the charger is, and there are several devices in a phone (the radio transmitter for a start) that demand high transient currents from their power source. So the phone is wired to charge the battery from the charger & power the phone from the battery - it cannot run itself from the charger. I don’t know whether the same is true for modern laptops.

Hi Domenico, a swollen battery won’t necessarily catch fire but is at much higher risk of doing so. Many house fires have been started by batteries catching fire. Why risk it? Take your phone to a mall repairer and have them install a new battery for peace of mind.

Actually Andrew, I thought the same as you about constant charging but we both appear to be wrong! According to Battery University, constant charging may in deed be stressing the battery. In my case, my Wife and I got iPhone 6s Plus models at the same time. I am mostly at home and have kept my phone pretty much on the charger all the time. My Wife uses hers normally, charging overnight. My battery seems to be failing while hers is still working normally.

As Andrew mentioned, the charge controller inside the phone disconnects the power coming from the charger when battery is fully charged (this information is coming from the battery microcontroller).
Coming from my personal experience with old phones and smartphones:
I have kept some old Nokia phones and Samsung smartphones connected day and night to their chargers for weeks.
All this time they were on, equipped with SIM and connected to the mobile network or WIFI.
I didn't notice any major changes on battery lifespan for months or even years.
As long as the charge controller is doing its job, I will not worry about.
I will be suspicious if I notice the phone heating during charging as long as the WIFI, MOBILE DATA or LOCATION are disabled or the device is in IDLE and/or FAST CHARGING is deactivated on the phone.
I'm no expert in Li-Ion battery, just sharing my long time experience using them.
Iti Tech -
What that Battery University article claims depends on various factors. A properly designed charging circuit does not continue trying to push charge into a fully charged battery. It is technically true that fully charged is more stressful for a battery, but then so too is running the battery down. A charge cycle is also a complete discharge and recharge, so it takes many small topping up charges to make up one charge cycle. So I think it is complicated and really not easy to determine what real world scenario actually works best.
Ian -
Very interesting, Roger!
Experience with my iPhone 6, which has just 4 hours daily off-charge use, is that 2 years after Apple replaced the phone with a brand new (but old stock?) one due to a faulty charging circuit the battery health is still showing 100%. On the few occasions I haven’t charged it at all during the day but used it heavily, it typically has about 25% of charge remaining at the end of the day.
Maybe it helps that my phone is kept in an air conditioned office all day, and a cool bedroom at night while it charges, and I rarely use it while it’s plugged in to charge.
It wouldn’t be very difficult technically for Apple and other phone manufacturers to have a charging circuit that disconnects the battery once charged (optionally to a user-set level between the 40% optimum and 100%) and powers the phone directly from the charger. Batteries in phones that are mostly plugged in would last forever, but then there would be less incentive to replace your phone every few years, so it would hurt sales.

Ciao, una informazione per favore:
può una batteria perfetta di un MacBook Pro Early 2011 gonfiarsi da sola durante un lungo periodo nel quale il computer è rimasto inutilizzato?

Hi Marco, yes, a battery can become swollen during storage. The swelling is due to gas build up in a battery that is deteriorating. It’s possible your MacBook Pro battery had started to deteriorate - particularly given its age - prior to or during the repair period.

km design - 回复
Surprisingly enough, Massachusetts STILL doesn't have an e-waste recycling law, even though people have been advocating for one – and various bills have been born and died in the state legislature – for more than a decade already. The only exceptions are landfill bans on CRT (tube) display screens, and on devices containing mercury. The second law would cover most older flat-screen displays, due to the fluorescent backlight. Newer, LED-backlit screens wouldn't even necessarily be prohibited under that law, so you can still just throw 'em out like yesterday's newspaper. (Actually, no - those you have to recycle!)
Of course, for anyone in MA who's left holding a swollen battery, that's BAD news because, even if you could apparently just chuck it in the trash, you for sure shouldn't. But, options for safe disposal are likely pretty limited, given the uncharacteristically permissive legal situation that somehow still persists in such a bastion of New England granola-liberalness... liberalhood... liberalty?

The question I’ve yet to see answered is over what period of time does a battery swell? My laptops have cases that can easily be opened and I can inspect the battery to make sure it is still in good shape and not swelling, but I don’t know if the swelling is something that happens in a day or two (or less) or gradually over time, like an electrolytic capacitor. Anyone know?
Asc aris - 回复
Unfortunately, the not-entirely-helpful answer is, "It depends". Most swelling is gradual and minor -- but as Arthur Shi says in a reply farther down, that's also not the type of swelling you have to worry about.
Catastrophic, major swelling (like you see in the photos accompanying this article) is the real danger. That sort of swelling can come on very quickly indeed, especially if it's caused by an event like a device drop, or exposure to water or excessive heat. By "very quickly" I mean in a matter of hours or days, up to perhaps a week or two.
In those cases, generally a battery inspection won't be your first indication of it happening — you'll see a sign like the ones described in the article: deforming of the outer casing, changes in the feel of buttons, keys, or trackpads, etc.
The first sort of swelling won't necessarily ever develop into the second, nor is it a prerequisite for severe swelling to develop. So, regular battery inspections probably aren't really all that useful, TBH.
FeRD -
The real concern is when there's a situation that might cause you to miss those secondary battery-swelling warning signs. In those instances, inspections for signs of swelling may be warranted. They don't even need to necessarily go as far as inspecting the battery itself.
For example, I had a Samsung Galaxy Note8 that developed severe battery swelling. Because I had the phone in a rubberized wraparound case, that case hid the signs of swelling so well that I didn't notice anything amiss until the swelling had already gotten way out of hand.
How out of hand? The swollen battery pushed the (glued-on!) back cover of the phone completely off, breaking the phone's rear camera in the process!
So, in situations like that, popping the phone out of the case every few weeks and checking it for signs of swelling is something I'd recommend, more than worrying about inspecting the battery itself.
FeRD -
Well I wish I read this awhile ago. I punctured a battery with some tweezers. It burst into flames. I ran into the bathroom and threw the whole phone into water. The phone survived! I was really surprised at the chemical energy and how fast that released, so I urge everyone to take this very seriously. I’m an electrical engineer so I should have known better and been more patient. I’ve wondered how many years I may have lost by inhaling the caustic smoke that was coming from that. I wished that my wife and daughter hadn’t witnessed that event, because my “mr. fixit” rep was seriously tarnished that day.
Michael Conway - 回复
Well, you shouldn't wish that your wife didn't witness it. Your children are supposed to think you're capable of anything and everything, but it's okay for our spouses to know our limitations and embarrassments. Your "rep" shouldn't mean anywhere near as much as sharing.
Autumn West -
I just left a product review for a battery I purchased for a 2015 MacBook, but I’d like to mention this here as well:
When replacing batteries that are adhered to the casing of a device, make certain that the battery is completely depleted before removing it. I didn’t do that and mine caught fire and exploded. I was carefully (but firmly) sliding a credit card under the old battery when it caught fire. That most likely wouldn’t have happened if I’d drained the old battery first. No damage done, but definitely was not a fun experience.

Hi, I just realized that my Surface Pro 4 battery is beginning to swell. The screen is bulging in the middle. I contacted MS but their solution was just to purchase another Surface Pro. This machine has a BIOS option to only charge the battery to 50% (when the device is used as a kiosk). So, I set it up only to charge to 50% while I am using it and at the end of the day I unplug it from the docking station and shut it down. I wish I would’ve known about his feature when I bought it from the reseller. I also have a Dell Inspiron laptop that has a battery management tool. Which limits full charging of the battery when the device is always plugged in. So, I’m not sure what to do regarding the SP4. I should start using the Dell and recycle the SP4 to avoid any potential fire hazard. My Mom has a HP Pavilion that is always plugged in but unfortunately HP only provides a battery management tool for business devices but not personal devices which is ridiculous. I told her to occasionally use it in battery power.
fivan - 回复
Hi Fivan!
The battery swelling is a result of the battery electrolyte decomposing into gas. Very minor swelling is OK—you'd just experience decreased battery capacity. But, if the battery's pushing the screen up...it's time stop using it. Batteries inevitably wear out. Take a look at this guide and see if you want to try to replace the battery yourself.
Arthur Shi -
When I replaced the original drive in my refurbished 2012 Mac Book Pro, I noticed that the battery is swollen a bit and feels soft when touched. From outside nothing indicates this and MacOS still thinks that the battery is ok. So I left it inside and had no problems with it since several years until now.
MEX - 回复
"A bit" of swelling isn't unusual as batteries age, and isn't necessarily a cause for alarm. The thing to watch out for is severe swelling (bad enough to potentially deform the case / surrounding components), or swelling that occurs suddenly and/or in response to some outside event — if the device got wet, or was dropped, that sort of thing.
The OS is unlikely to ever notice anything amiss, even for severe swelling. The battery's performance typically isn't affected until (that is to say, if) it goes nuclear. Meltdowns aren't guaranteed, either, they're just a very real danger and can happen with little to no warning. So it really is a risk continuing to use a device with a (severely) swollen battery. Plenty of people still take that risk, and statistically most of them won't end up having any problems... but enough people DO that it really can't be considered safe.
If your laptop's using the original 2012 battery, it's probably just dying of old age.... totally unrelated to any swelling.
FeRD -
(Actually, if you have a battery from 2012 that still holds any charge, then it is a miracle device that lasted far longer than anyone could've ever expected it to. Heck if the battery's from any year before 2016, that's %#*@ impressive.)

In the how to remove section it says "Run the battery down as low as you can" - My question is how do you do this, that does not take hours or days?
Anthony - 回复
There's no easy way, you do basically have to just run the battery down through use. Sometimes, you can use software that taxes the system, and drains the battery faster — things like benchmarks, graphics demonstrations, etc. that just naturally consume a lot of battery power — and that can speed the process along. But for the most part, the answer is simply, "just keep using the device without charging it until it runs out of power."
FeRD -
If the battery is already prying apart the the device in which it is used, give the device to a PROFESSIONAL, or remove it as soon as possible yourself and put it in a metal bucket with SAND below the battery because of fire hazard !
If the device doesn’t show any signs of bloating, just discharge the battery by viewing Videos or other tasks which use much energy until the device shuts down itself because of low battery. Then disassemble the device and remove the battery, storing it in a fireproofed metal container which you put into a bag ( don’t keep this battery in a pocket of your clothing because of fire hazard ! ) and bring it to a store or waste facility which knows how to handle bloated LiIon batteries as soon as possible.

Ed Sheeran - 回复
Usually the company which SOLD you the device with the battery is responsible for recycling it !
If you bought the device ONLINE, it is usually better to look for a shop in you area wich was selling these product, or is selling newer versions of the same BRAND and ask them if they take back the defect battery. I live in Vienna, Austria, EU and here these shops usually don’t charge extra for taking back single defective LiIon-batteries. Otherwise ask a repair shop in your area if they take the defective battery cheaper.
MEX - 回复
Many towns have a hazardous material disposal, either all the time, or once a week, or once a month, you bring the swollen battery to them. I heard Best Buy will take old Laptop Batteries for safe disposal also. Your mileage may vary on that though. It might take a little research. But you absolutely can't just put the batteries with the regular trash.
Anthony - 回复
Best Buy definitely does offer electronics recycling, and for the most part free of charge — there are certain exceptions, like LCD screens (which they charge a hefty recycling fee for). Most of their locations have a battery drop-off bin right at the entrance, in fact. (Other electronics recycling, you have to go to the customer service desk to drop off your items. There's also a limit of like 3/day, IIRC.)
However, all that being said, I don't know what their policy is about taking swollen batteries, and I would check with them on that before going in. Definitely don't just drop it into the battery bin, that doesn't sound safe at all.

My Planet computers Cosmo Communicator battery is pushing the back off the phone, but they have stuck it in with so much super powerful glue tape, I can't even get to see the model labels under it. Looking for others with same problem, I read the model as 'SX600'. I can't find anything but old pictures of it from cos that don't sell them any more or don't deliver to the UK, yet the manufacturer is still selling the phones but expect us to send them to be 'repaired' at great expense! I use the device all the time! :(
I think it ought to be illegal fo manufacture devices that the battery cannot be very quickly removed, by simply opening the back and popping it out as all devices used to be made before the infernal i-phone came along and everyone else copied it to make us throw away perfectly usable devices every year or two! Manufacturers are effectively selling us incendiary mines that can't be disabled. Why was tis ever allowed?
Can I jump the connector from an external power supply/battery?
Spamlet - 回复
(1/2) I doubt it's entirely fair to blame Apple for this; they may not have even been the first manufacturer to use a non-removable battery pack. They were certainly the first biggest company to make that switch, but plenty of others did the same, and in some cases way too quickly for it to have been a case of them "copying" Apple. They simply came to the same conclusion: Removable batteries, like physical keyboards, hurt sales more than they helped. So, out they went.
Because, the frustration of it is that device manufacturers genuinely have really "good" reasons why batteries are no longer removable. Actually, at least two good reasons: Water-resistance and miniaturization.
Today's phones are surprisingly watertight, to the point where many can survive a brief dunk with no immediate ill effects. (Though I personally suspect that water infiltration is a trigger for subsequent battery swelling.) My Galaxy Note8 once survived a complete submersion lasting 2-3 seconds. Don't try that with your Nokia 3310!
FeRD -
(2/2) All battery-powered devices are also continually getting smaller and smaller. (Or, failing that, they're packing more and more stuff into roughly the same amount of space.) And the fact is, removable batteries require MUCH more space than non-removable.
If a battery is removable, it has to have an outer, protective case of its own due to the dangerous chemicals inside. The phone would then also have to have mechanisms to align and secure the battery, a latch and release mechanism, and electrical contacts between what are now (effectively) two completely separate devices. That all takes up space.
A removable battery makes a device significantly larger (in particular, thicker), or else it has half the capacity of the non-removable design. Either way, 999 out of 1000 consumers will choose the smaller, thinner, lighter fixed-battery device with twice the runtime between charges, over a bigger, thicker, doesn't-last-as-long alternative with a removable battery.
FeRD -
Actually, now that I think about it there's a third reason that's even more damning:
Removable batteries were never about extending device lifetime.
Manufacturers will tell you, and they can provide reams of consumer data to back it up: The percentage of consumers who keep a device long enough to wear out the first battery is TINY. Laughably tiny. The overwhelming majority of mobile-device owners want to replace their device with a newer, faster one every 2 years or less — long before the battery is even starting to degrade. (After all, until very recently the technology was advancing so quickly, a 2-year-old phone was nigh-unusable, given its limitations compared to newer models.)
Removable batteries were always intended for power-users who needed more runtime than they could get from a single battery. They'd own two+, and swap them out as needed (charging externally). In the end, rapid charging, larger capacities, and improved power-management software provided a better solution to that problem.

Bought a replacement battery for a 2011 MacBook Pro in 2020. Since then, the machine has barely been used, maybe 100 cycles. The rest of the time it lives under the coffee table. But last night I took it out to play a DVD and the whole mouse pad was almost pushed out by a swollen battery barely 2 years old. The original battery lasted 10 years and did over 2000 cycles.
So where does iFixit get their batteries? This is now the 3rd iFix battery between 2 laptops that has gone bad by swelling.

Reading THIS I am reluctant to replace my 10 year old battery in my MacBook Pro with a new one from ifixit … it already feels SOFT and looks a bit swollen since several years, but doesn’t pry my laptop apart ( noticed it when I replaced the HDD with SSD )

I have now removed the dud iFixit battery from my laptop and run it without one installed seeing as the machine doesn't go anywhere anyway. It is only used as a coffee table DVD player. So no, I don't think I trust iFixit batteries anymore. 3 strikes, and you're out!
Sad thing is I threw out the original battery which still worked for 2 or 3 hours. No swelling whatsoever after 10 years of solid use.

This is not the place to complain about the ifixit 3rd party batteries. There are no ifixit employees here.

It isn't? Then what is this comments section for? But ok, what to do with a swollen battery? Don't get one from iFixit and you won't have the problem of wondering what to do with it. Maybe some iFixit employees want to keep an eye in here to see what ex customers think of their products. Anyhow....

Actually I can’t complain about iFixits batteries as I haven’t bought any until now ;-P

Yea, I guess I was just unlucky as a majority of iFixit batteries don't do this? Either way, I don't think I care to take this further as even though this particular battery was hardly used, it was over 3 years old so I would think the warranty is over anyway, and I have since got rid of the evidence, I really don't need any fire-starters lying around. Also, I don't actually need a battery anymore in this machine as it is now only used as a coffee table DVD player.
On the other hand, maybe this is happening more than anyone cares to admit. I have some old cell phones from the 1990's, and while the batteries don't work at full capacity anymore, they do still work a bit, but most importantly, they are not swollen, at all. Of all the Li-Ion batteries I've ever handled, iFixit laptop batteries are the only ones that have done this.
No, I'm not fishing for any kind of compensation or the like, but hopefully this prompts better quality control going forward. Imagine aircraft or even electric car batteries did this...

That being said, there's no question in my mind that battery swelling is on the rise, across the industry. (There are only like six factories that manufacture all the world's battery cells.) The cause of death of four of my last five cell phones was swelling of the OEM battery it came with. (#5, I dropped face-down on a ceramic toilet rim. Oops.)

All I can do is guess why that might be the case, but there are some factors that seem likely to be contributors:
• Much, much higher power draws. Modern mobile devices are hard on their batteries, running them hotter and draining them faster than devices ever did in the past. There's gotta be a reason the other big epidemic of battery failure was with "hoverboards", which also have insanely high power consumption.
• Internal, non-removable batteries' "soft" shells are poorer protection from the environment. Your typical Nokia 3310 had a 900-1000mAh battery (!!), encased in a hard plastic shell of its own, and its connection to the phone consisted of a few flat metal pads. It didn't get hot (even if the phone did), it didn't get wet (ditto), its chemistry wasn't subject to being screwed up by exposure to the elements.
• Fast-charging systems likely tax batteries more than older, slower chargers. Being "designed" to accept higher charging currents doesn't mean there isn't longer-term damage being done.

부풀어 오른 배터리를 카메라 플래쉬를 켜놓고 저절로 꺼질때까지 방치한후 휴대폰으로 부터 분리했습니다. 분리된 리튬이온 배터리의 비닐커버에 바늘등으로 구멍을 내면 어떻게 되나요?

I would like to add some point:
Simultaneously battery-charging whilst using the device: been safely doing this for years with laptops. Reliable electronics at work, but phones have limited space. Hopefully, not too compromising. Battery status is only an assessment. Demands very accurate monitoring during charging and discharging. Found only in quality products with quality design.
Battery life: Batteries die due to chemical deterioration of its anode. This is minimised when the battery is maintained at full charge. This has been for years in our cars with modern day alternator etc+electronics. Working a charge/discharge cycle between 80% to 100% capacity can many times increase the life cyle figure. As in electric-cars Lithium cell voltage is 3.6v. Phones are 4.0 to 4.2 to increase capacity but shortens its life if at 3.6v
Water: Lithium is reactive in water like but less than Sodium. Plunge in big bucket of water for a small battery. Problem becomes contaminated water. Please! NOT in sewer or land drain!!

Do you sell hp14-cf0013dx batteries
Debi Stevenson - 回复
I do not sell batteries ...but look at green cell on https://www.ebay.com/itm/325417297797 for your HP 14
I've used green cell's replacement battery for my old Sony laptop for a couple of years now and ... I am very satisfied with it.
