Abstract

Because of the non-uniformity of internal resistance,voltage and capacity of single cell of the valve-regulated lead acid(VRLA) battery,the differences would be expanded in using and the cycle life of the battery group shortened.The reasons were analyzed.The charge performance of the slow pulse fast charge method was studied.The result showed that the method was hepful to balance charging of VRLA battery,reduced the non-uniformity of single cell,extended the life of the batteries to more than 700 cycles.
