What is the important cause of lead-acid battery fire

1) The separator is of poor quality or defective, allowing the active material of the electrode plate to pass through, resulting in virtual or direct contact between the positive and negative plates; 2) The active material on the electrode plate swells and falls off. , The lower edge or side edge of the negative plate is in contact with the deposits to cause the positive and negative plates to be connected; 3) The lead flow formed when the electrode group is welded is not exhausted, or there are lead beans between the positive and negative plates during assembly. The separator is damaged during charging and discharging, causing the positive and negative plates to be connected. 2. Abuse of the charger. Since the positive and negative poles of the charging port between different chargers are different, it will have reverse connection phenomenon. First, it will quickly charge your battery and damage it. Second, because the charger operates in a wrong way. , It will easily cause short-circuit and burning to the charger, so when charging, you should use the original or unified charger. 3. Overcharged lead-acid batteries will electrolyze the moisture in the battery electrolyte when they are overcharged. Hydrogen and oxygen will appear after being electrolyzed. These are flammable and explosive gases. When there is hydrogen in the battery or in the air When the accumulation reaches the explosive limit, it is very likely to burn or explode when exposed to an open flame outside. When you use electric vehicles and cars, you must pay attention to the usage of the battery, especially when it is charging, which is the most likely to cause accidents. I hope you will pay more attention to the maintenance of the battery to avoid potential accidents. Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
