XU Man-zhen (Guangdong Postal and Telecommunication Technology College, Guangzhou Guangdong 510630)
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.
