My battery is swollen, hot or damaged. What should I do?

Stop using it and stop charging it immediately. This applies if the battery is swollen, unusually hot, smoking, leaking, has got wet, or has been dropped or physically damaged.

Move it away from anything flammable and leave it alone. Do not try to test it, discharge it or charge it to see what happens.

Then file a claim and tell us what happened. Mark it as urgent, because our team treats battery damage as a priority case.
