1. Reasons for the production process
Although the production process of the battery is relatively mature, the production process of some small and medium-sized manufacturers is still relatively backward. In the production process, there may be cases where the sealing is not strict and the crack of the outer casing is not detected. Such a battery with a backward production process has a large potential for leakage.
2, the cause of the collision
Whether during transportation, handling or installation, the battery may be cracked by collision, which may lead to leakage in the later stage. The outer casing material of the conventional lead-acid battery is mostly ABS material. Although the hardness is very good, the toughness is relatively poor, which is what we call relatively brittle. When a relatively strong impact is encountered, the impact force is greater than the ABS material itself. The outer casing of the ABS material may be cracked when it is able to withstand.
3. Reasons for long use time
When the battery is used for a long time, some seals reach the service life and are prone to liquid leakage.
Although the above describes the cause of battery leakage, in the actual use process, the above three are only the premise of leakage. Under normal circumstances, the battery in use, especially the battery in the charging process, will cause the battery to leak due to the above reasons. liquid. During use, the battery heats up and the liquid inside the battery expands, so there is leakage.
