摘　　要：密封铅酸蓄电池内部失水是引起电池早期失效的主要原因。对造成电池内部失水的种种因素进行了分析,并提出了相应的改进措施。在改进电池板栅、密封及散热后,电池的使用寿命延长超过了50%。The premature failure in VRLA battery mainly attributed to the inner water loss. The reasons which made the inner water loss were analyzed and relevant methods were advanced. After improving the grids, sealing and heat dissipation, the VRLA battery service life was prolonged over 50%.
