What are the causes of self discharge of Panasonic battery?

Panasonic battery will discharge by itself in the process of use. Do you know what causes the battery to discharge by itself? Here is a detailed introduction:
1. A current path is formed between the positive and negative electrodes. The main reason is that the battery cover surface is polluted by the electrolyte and dust, so the battery surface should be kept clean.
2. The plate is damaged. Due to high current discharge or charging, the plate warps due to the expansion of active material, leading to the falling off of active material, or the partial short circuit caused by the damage of partition board, which will also cause the battery to discharge itself
3. When the battery is not used for a long time, sulfuric acid precipitates in the electrolyte, which makes the density of the electrolyte up and down inconsistent, forming potential difference on the electrode plate, and causing self discharge.
4. The electrolyte is impure or mixed with the metal conductor, which forms a circuit between the impurities or between the impurities and the electrode plate, causing the battery to discharge by itself.
