Understanding Battery Safety: The Consequences of Overcharging

In a recent demonstration, a battery expert illustrates the potentially dangerous effects of overcharging a cell, emphasizing the importance of proper handling and monitoring of lithium-ion batteries.

Visual Indicators of Overcharging

The demonstration begins with the presenter intentionally overcharging a single battery cell. As the process continues, the cell begins to bulge visibly, a clear sign of stress and impending failure. This physical deformation, often overlooked by novices, is one of the first warning signs that a cell is experiencing conditions outside its safe operational limits.
