| [title|What to do with a swollen battery] | |
| - | |
| - | [toc] |
| [summary]Removal and disposal of a swollen battery can be dangerous, but leaving a swollen battery inside a device can also cause serious harm. Read all warnings carefully and proceed at your own risk. All batteries are hazardous waste and must be disposed of properly.[/summary] | |
| == Fire safety == | |
| - | |
| + | ***If your device feels extremely hot, or smells awful, don't attempt to remove the battery. If your device is actively emitting smoke, clear the area of anything flammable and don’t breathe the fumes. Ventilate the area if possible as batteries contain a cocktail of chemicals that are harmful if inhaled.*** |
| - | If you cannot move the device, you can smother the fire with sand, an approved fire extinguisher, or cover it with a fireproof container, and then stand clear. '''Do not use water under any circumstances as the lithium could react with the water and cause a fire.''' If you can safely move the device, put it in a fire-safe or well-ventilated area such as one with a concrete floor—and then stand clear until the battery is cool. Once a battery catches fire, the reaction will continue until the fuel is exhausted. |
| + | If the battery catches fire, treat it like any other small fire. If you can’t move the device, smother the fire with sand, cool the reaction with a foam, ABC, or CO2 fire extinguisher, douse it with lots of water, or cover it with a fireproof container–and then stand clear. |
| + | |
| + | If safe to do so, use fire-resistant tools like a metal spatula to push the device onto a fire-resistant surface like a metal baking sheet or concrete floor. Move the device outside to a safe location where the battery can burn itself out, while monitoring from a safe distance. |
| == WARNING == | |
| - | |
| + | ***Whether swollen or not, lithium-ion batteries may catch fire or explode if handled improperly. Proceed with caution and at your own risk when removing a battery from an electronic device. If you have doubts about your ability to do so safely, power down and isolate the device, and consult a professional repair technician.*** |
| - | Removing a swollen battery can be hazardous, but leaving a swollen battery inside a device also poses risks. To prevent potential device and bodily harm, a device should not operate with a swollen battery. These guidelines offer best practices for removing swollen batteries, but cannot guarantee a safe repair. If you have doubts, power the device down, place it in a fireproof container, take to a repair professional and ask them to remove the faulty battery. Do not delay battery removal. If your swollen battery was purchased from iFixit, take photos of the battery before and after removing it, then [https://help.ifixit.com/|contact our customer service team] for warranty claims or replacement. |

| + | Lithium-ion batteries use a chemical reaction to generate power. As the battery ages, this chemical reaction no longer completes perfectly, which can result in the creation of gas (called outgassing), leading to a swollen battery. Additionally, if the battery’s internal layers don't maintain proper separation (due to damage or defect), outgassing, swelling, and even fire can occur. Other common causes of outgassing include flaws introduced during the manufacturing process, overcharging, and excessive temperatures - all of which can lead to unwanted chemical reactions inside the cell. |
| == How to identify a swollen battery == | |

You may notice a sweet, metallic, or acetone smell, which could be battery gas escaping a swollen battery. |
| === Inspect the battery === | |
| === Before you begin === | |
| - | |
| + | ***If you suspect your battery is swollen, don't charge your device.*** Run the battery down as low as you can—this reduces the risk of fire. |
| === Protect yourself === | |

Water isn't the most effective option, but [link|https://batteryuniversity.com/article/bu-304a-safety-concerns-with-li-ion|can be used in large quantities to extinguish] a small, cellphone-sized battery (less than 15 Wh). If you work indoors, have a clear path to a place outside where the battery reaction may safely run itself out. |
| === Remove the battery === | |
| == How to dispose of a swollen battery == | |
| - | Once the battery has been removed, it needs to be safely disposed of. '''Do not throw batteries into trash or recycling bins. Do not put/store the battery in water.''' If the battery is warm, smelly or smoking, put it outside away from flammable materials, or in a fireproof container, and wait for the symptoms to dissipate. When safe, take the battery to a local e-waste collection site; refer to our [[E-Waste|e-waste page|new_window=true]] to find one in your area. Do not mail the battery to an e-waste processing facility—there are strict regulations against this as the battery could cause damage in transit. |

| - | == All batteries are hazardous waste == |
| - | |
| - | Disposal of batteries requires special attention. In any condition, all batteries pose a fire and safety hazard and should be handled and disposed of properly. Batteries can not be placed in municipal waste collection, and must be taken to a hazardous waste collection facility. Find a hazardous waste collection facility through [https://search.earth911.com/|Earth911] or an internet search. |

| + | Batteries are consumable, and no matter how well you take care of them, they will eventually need to be replaced. That said, below are some best practices to help keep your battery healthy for longer. But, it is important to note that you cannot heal a swollen or defective battery; you can only remove it. These hints can only help ''prevent'' battery degradation. |
| - | Batteries do best with slow, controlled charging and discharging, use in moderate temperatures, and protection from shocks or damage. |
| + | Batteries do best with slow, controlled charging and discharging, use in moderate temperatures, and protection from shocks or damage. Though a phone or laptop battery isn’t usually being charged or discharged quickly enough for it to pose an issue, rapid charging and discharging ''can'' wear a battery out prematurely and result in some outgassing. Avoid using low quality or damaged charging cables or adapters as they risk uncontrolled, uneven, or excessive power management that can cause damage or even result in fire. Leaving your battery 100% charged or completely empty for a long period of time can also shorten your battery’s lifespan, so if you plan on storing your device without using it for a few weeks or more, charge/discharge it to about 40% and turn it off beforehand. High temperatures can also reduce battery efficiency, so try not to leave your phone in the car on a hot day. And most importantly, dropping your phone hurts your battery, too, not just your screen. Just like cars, phones are meant to flex during an accident, so even a glued-in battery can bump into nearby components when dropped, resulting in a puncture. Replace your battery if it’s damaged or no longer holds a proper charge. |
| TL;DR: be nice to your battery. Use it gently, and replace it if it becomes damaged or no longer holds a proper charge. | |
