1. Relief valve pressure is too high, or the safety valve is blocked. When the body pressure increases to a certain extent, the valve can not open normally, in this case will cause bulge deformation.
2. Floating charge pressure set too high, charging current, resulting in the positive plate on the O2 precipitation accelerated, but not too late in the negative compound, and the temperature in the body of the battery rise also quickly, in the exhaust, pressure to achieve a certain time, so that the VRLA battery bulge deformation.
3。 VRLA battery charging operation, especially in the series battery, if the battery pack has been charged, if there is bad quality of the battery often appear internal gas composite undesirable phenomenon, and thus appear bulge phenomenon。
4. Because the Vrla battery belongs to the poor liquid design, the combination of gas reserved to avoid the road, and if there is a "rich liquid" phenomenon, will block the resulting O2 diffusion to the negative, reduce the O2 compound rate, the body pressure increases.
