阀控式密封免维护铅酸电池与其他电池不同，实际上它不可能完全免维护，只能减少维护工作量，电解液蒸发少，不漏液。由于充电器还没有达到完全理想水平，仍然避免不了水分的少量蒸发。对于稍懂一些电池知识的用户，而且容量明显下降，可自行考虑适当加水使电解液恢复原来浓度或适当低于原有浓度，对极板较有利。天力蓄电池
Valve controlled sealed maintenance free lead-acid battery is different from other batteries, in fact, it can not be completely maintenance free, only reduce maintenance workload, less electrolyte evaporation, no leakage. Since the charger has not reached the perfect level, it still can not avoid a small amount of evaporation of water. For the users who know some battery knowledge, and the capacity is obviously reduced, it is better to add water to restore the original concentration of electrolyte or lower than the original concentration.
