Why does the battery bulge deformation phenomenon?
1, the safety valve opening pressure is too high, or the safety valve is blocked. When the pressure in the body increases to a certain degree, the valve can not open normally, in this case is bound to cause the deformation of the bulge.
2, float charging voltage is set too high, charging current is large, resulting in the positive plate O2 precipitation accelerated, but not in time in the negative compound, while the temperature inside the battery also rises quickly, in the exhaust is not enough, when the pressure reaches a certain point, so that the VRLA battery bulge deformation.
3, VRLA battery charging operation, especially in series battery pack, if the battery pack is overcharged, if there is a poor quality of the battery often appear internal gas compound poor phenomenon, so that the phenomenon of bulging.
4, because the VRLA battery is a liquid-poor design, the gas combination of the reserved channel, and if there is a "rich liquid" phenomenon, it will block the diffusion of O2 to the negative pole, reducing the rate of O2 compound, the internal pressure increases.
