Battery swelling refers to the abnormal physical expansion of a battery, often caused by the buildup of gas inside the cell due to electrochemical reactions gone wrong, internal short circuits, or degradation processes. It is a sign of potential battery failure and can pose serious safety risks, including leakage, fire, or explosion.
Prevention Tips
Use certified chargers and BMS systems
Avoid extreme temperatures (both hot and cold)
Do not overcharge or over-discharge
Regularly inspect batteries in high-cycle or critical systems
