Application of slow pulse fast charge in capacity restoration of VRLA battery

MA Yi-chun

Abstract

The capacity of the failed valve-regulated lead acid(VRLA) battery was restored by the slow pulse fast charge method.The results showed that the capacity of the failed VRLA battery could be restored to 90%～100% rated capacity.The(average) cycle life of VRLA battery after restoring the capacity reached 150 times and the life of VRLA battery was extended indirectly.
