Will a hot charging battery explode?

[OBryce]

Battery heating during charging will not cause an explosion. It is normal for a car battery to heat up during charging. When the battery is charging, the electrolyte inside will be in a boiling state, so when you touch it with your bare hands, you will naturally feel the battery heating up, and theoretically, there is no risk of explosion. Below are some relevant details: 1. Abnormal heating: If the heating is abnormal, it may lead to thermal runaway of the battery, causing it to swell. This abnormal phenomenon occurs because the car battery has become severely sulfated and requires timely repair. 2. Repair method: The method to repair a sulfated battery is to discharge the battery, then pour out the original electrolyte, and charge it with a low current within a temperature range of 20 to 40 degrees Celsius. After the charging is completed, the sulfation phenomenon will be eliminated, and the battery capacity can basically be restored to more than 80%.
