Possible reasons for a zero or low voltage on the battery are:
1 The battery is subject to external short circuit or overcharge, reverse charge (forced over discharge);
2 The battery is continuously overcharged by high current and large current, causing the battery core to expand and the positive pole to directly contact the short circuit;
3 The battery is internally short-circuited or micro-short-circuited. For example, the positive and negative plates have burrs that penetrate the diaphragm paper and are short-circuited.
Improper, causing the contact of the pole piece to be short-circuited, or the positive electrode sheet is short-circuited with the steel shell, the negative electrode is dropped into the diaphragm paper, and the diaphragm paper itself is missing.
The trapped positive electrode tab is short-circuited to the negative electrode tab.
