通信用阀控式铅酸蓄电池供电可靠性的讨论

阀控式铅酸蓄电池（VRLA）是目前支持通信系统工作的主要备用电源。VRLA电池在浮充条件下的缺点已在国际会议上经过多次专题讨论。国内用户的反映是，当市电发生故障时，电池单体放电容量往往达不到设计要求。本文分析了一些影响电池可靠性的重要因素，提议在使用维护过程中改变充电方式，并在选购产品时要注重电池的基本性质。

Discussion on power supply reliability of VRLA batteries for telecommunication systems

VRLA batteries are main standby powers to support communication systems. The disadvantages of VRLA batteries under the float charging conditions had been discussed at many international battery conferences. Most domestic users said that the discharging capacities of cells often failed to reach design requirements when the main power was interrupted. This article analyses some important factors that have influence on the liability of batteries, and proposes to change charging methods during usage and maintenance, as well as to lay stress on the performances of batteries which are chosen by users.
