Different types of cells, causing the expansion of the reason is not the same as for the expansion of rechargeable batteries because:

1. Battery Protection Circuit ill

2. Battery protection function does not increase battery

3. Chargers’ poor performance, causing the battery charging current is too large an expansion of

4. The battery through a process of continuous overload at high speed high current

5. The battery itself, the design problem may also occur

The general expansion of the battery cell is mainly due to:

A, the impurities of raw materials

b, electrolyte precipitation

c, stored in damp
