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。

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.

Iti Tech -
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.
Yannik -
Do not use water under any circumstances as the lithium could react with the water and cause a fire - this is misleading. While it’s true that lithium ignites on contact with water, there is actually very little elemental lithium in typical lithium-ion batteries and a sufficient quantity of water can put out the fire that water started.
For example, on board commercial aircraft if a passenger’s phone catches fire (which happens frequently when a phone falls down the back of a seat and the passenger adjusts the seat angle to get at the phone but in the process squashes it, puncturing the battery), the standard procedure is to use bottled water or soft drink to extinguish the fire.
Andrew - 回复
Thank you Andrew for commenting on the use of water to extinguish a Li ion battery. You are 100% correct. In fact, there is a lot of test data that has been produced by NFPA that shows water is the most effective (and safe) way to suppress a Li ion battery fire. Water also immediately cools down any adjacent cells to prevent propagation.
The heading that states “All Batteries are Hazardous Waste” is also wrong.
This website should be corrected ASAP.

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?
Lo chiedo perché ho portato il primo a farlo riparare (non funzionava più la scheda video) e dopo tantissimo tempo (oltre un anno) mi hanno restituito un computer mezzo distrutto con la batteria gonfiata….
Marco - 回复
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.

Reevaluate this for newer USB-C (Type-C starting at USB version 3.1 and up) which supports much higher Watts/Power than older USB types (A, micro, etc.). Non-compliant USB-C chargers have destroyed equipment.

Buonasera, ho un avviatore di emergenza per batteria dell’auto che dopo un primo utilizzo si è leggermente gonfiato. Le sue dimensioni, simili ad un HD portatile, prima lineari sulle due superfici, ora al tatto e visivamente appaiono leggermente rigonfie.
Cosa mi suggerisce di fare ? Grazie
Gian Carlo Guarente - 回复
Purtroppo gli avviatori portatili economici sono molto critici perché erogano correnti molto forti direttamente dalle batterie al litio interne. Per questo le celle al litio, che di solito sono 3 per realizzare i 12 V necessari, si scaldano molto rapidamente.
Tra l’altro le 3 celle sono in serie per cui se una inizia a danneggiarsi, aumenta la sua resistenza interna e si scalda mentre le altre due cercano di compensare l’ostacolo “pompando” sempre più energia attraverso la cella difettosa. Ne risulta una reazione a catena che può portare a bruciare la cella in brevissimo tempo. Quindi, al di là della pericolosità, c’è il rischio che l’avviatore si bruci ancora prima di aver avviato il veicolo.
Diverso il caso degli avviatori più raffinati, in cui l’energia di avvio è scaricata da un condensatore, caricato progressivamente in tempi dell’ordine del minuto, quindi tramite batterie più “tranquille”. In questo caso il funzionamento è più sicuro, simile a quello di un normale flash elettronico.

Hoi,
ik had een gezwollen batterij in iPhone se deze nu vervangen maar hij laad niet op… dus weer vervangen maar ook deze laad niet op….
enig idee wat er aan de hand kan zijn ?
John - 回复
Hey John! Onze tech-afdeling raadt je aan het volgende te doen: het lijkt erop dat er iets mis is in/met het oplaadcircuit of de aansluiting zelf. Plug daarom een Lightning-oplaadkabel in de iPhone en test dan eens of je iPhone met een geluid of een teken aangeeft dat er een kabel aangesloten is. Als je een teken ziet of geluid hoort, dan kan het zijn dat er iets mis is met het circuit op het logic board dat verantwoordelijk is voor het opladen van de batterij. Als je iPhone niet doorheeft dat er een kabel aan wordt gesloten, kun je dit eerst dubbel-checken met een andere kabel/oplader. Het kan zijn dat de Lightning-aansluiting kapot is. In dat geval kun je deze handleiding volgen om deze te vervangen. We hopen dat je er aan uit komt! Mocht het niet lukken, stel dan vooral je vragen en dan proberen wij je te helpen!
Groet,
Thomas

I’ve just had a Anker power bank bust open its case and the two batteries in side swollen as anything. Fortunately no fires or anything but, I took it outside straight away and dropped it into metal bucket full of water hopefully that should be enough for it to die down and do its thing. Nothing happened when I put it in but watching it for a while it would have a single bubble 5-10mm every 5 seconds or so which would pop as soon as it reached the surface.
Its funny in some ways as I’ve not used that power bank for quite a while it has been charged for a while either literally just sat on my desk with nothing plugged into it.

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?

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.
