What are the reasons for the swelling of the battery?

Reasons for the swelling of the battery 1. The vent hole is blocked. If the vent hole on the battery filling cover is blocked or not unblocked, the gas that appears when the charging time is too long or the charging voltage is too high will gradually accumulate, causing the pressure in the battery shell to increase. The bigger the increase, the battery will swell. 2. The charging time is too long. When the UPS battery charging current is too large or the charging time is too long, a lot of gas will appear. In addition, too much current or too long charging time will also cause the electrolyte temperature to rise rapidly, and this will easily cause the battery to swell. 3. Vulcanization of the battery plate If the plate of the UPS battery is vulcanized, the cell voltage and electrolyte temperature will rise rapidly during the charging process, the appearance of bubbles is early, and the reaction is violent, it is easy at this time Cause the battery to swell.
