摘　　要：阀控式铅酸蓄电池内部的电解液全部吸附在电池的隔膜中,没有游离的电解液.是一种典型的贫液式电池,如果浮充电压较高,或长期在温度较高的环境中使用,就会引起电池失水速度加快,造成干涸失效,通过实验证明:补加一定量的水分,可有效减轻充放电过程中的极化,恢复电池的实际容量,延长电池的寿命。The electrolyte of the valve-regulated lead-acid battery (VRLAB) was adsorbed by the dissepiment. The VRLAB is a kind of representative lean electrolyte battery. If the floating voltage,or the ambient temperature was higher,the [led warier vapour from the battery will be increase and the battery will be dry failure in the end. The results of experiment proved that injecting some water into the battery can decrease the polarization of charging and discharge of ihe battery, recover capability of the battery, extend life of the battery.
