If there is a leakage, the main reason is: 1. Excessive internal pressure; 2. Unqualified external packaging

1、 In the process of battery manufacturing, if the following problems occur, it is easy to cause battery leakage:

1. When welding the battery casing and cap, there are problems such as loose and unsealed welding, missed welding, virtual welding, and cracks and cracks in the weld seam;

2. When sealing the steel ball, the size of the steel ball is not appropriate, and the material of the steel ball is different from that of the cap;

3. The positive pole of the cap is not tightly riveted, with gaps, and the elasticity of the insulation sealing gasket is not appropriate, which is not corrosion-resistant and prone to aging

2、 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, and the internal strength of the battery is insufficient;
