影响VRLA蓄电池使用寿命的原因分析

Analysis on the causes affecting the service life of VRLA batteries

对现有通信基站用法空式铅蓄电池的维护方法提出质疑;现普遍使用的检测静态内阻、消除"硫化"、提高浮充电压等维护手段,对延长电池的使用寿命均无显著效果,分析了问题的原因;提出了提高通信基站备用电源使用寿命的电池维护方法。

The maintenance methods for VRLA batteries used in communication base stations were questioned in this paper. The existing maintenance methods, such as testing static inner resistance, elimilating the sulfuric acid salinization, increasing the float charging voltage, had no distinct effects on prolonging the service life of VRLA batteries. The causes were analyzed, and some methods to prolong the life of VRLA batteries for communication base station were given.
