Talk about why the battery "drums"?

It is mainly due to the increase in pressure of pressure in vivo, and the main reasons have the following points. (1) The safe valve opening is too high, or the safety valve is blocked. When the pressure in vivo increases to a certain extent, the valve does not open normally, and in this case, it is bound to deform. (2) The floating charge is too high, the charging current is large, resulting in acceleration of O2 on the positive electrode plate, and is not as good as the negative composite, and the temperature rise in the battery is also very fast, in the exhaust, the pressure is time, VRLA battery is deformable. (3) Especially in the series battery pack, the VRLA battery is charged, and if the battery pack is overcharge, the internal gas composites often appear in the battery pack, thereby occult occurrence. (4) Because the VRLA battery belongs to the poor design, there is a reserved protection against the gas, and if there is 'rich liquid', it will block the generated O2 diffuse to the negative electrode, reduce the composite rate of O2, in vivo pressure Increase.
