Is It Normal for a Battery to Heat Up While Charging?

[LaJosie]

It is not normal for a battery to heat up while charging. Precautions for battery charging: Avoid storing the battery in a depleted state: A depleted state refers to when the battery is not charged in time after use. In this state, sulfation is likely to occur, where lead sulfate crystals form on the plates, blocking ion channels and leading to insufficient charging and reduced battery capacity. The longer the battery remains idle in a depleted state, the more severe the damage. If the battery is not in use, it should be charged once a month to extend its lifespan. Regular inspection is necessary: During use, if the electric bicycle's range suddenly drops by several kilometers in a short period, it is highly likely that at least one battery in the pack has issues such as broken cells, softened plates, or shedding of active material from the plates, leading to a short circuit. Battery charging duration: The battery typically requires 8 to 12 hours to charge.
