1、 During the battery manufacturing process, if the following problems occur, it may lead to battery leakage:

1. When welding the battery shell and battery cover, the welding is not firm, the sealing is not good, and there are problems such as missed welding, false welding, cracks and cracks in the weld seam

2. Steel ball sealing, improper size of steel ball, different materials for L-shaped steel ball and bottle cap

3. The positive pole of the cap is not tightly riveted, with gaps, and the insulation sealing gasket has inappropriate elasticity, corrosion resistance, and is prone to aging

II. Possible issues during use:

1. The battery is not original, with high voltage or current

2. The battery often bumps and damages the aluminum plastic film during normal use, resulting in insufficient internal strength of the battery
