Abstract-Dynamic Charge Acceptance (DCA) is an important consideration for battery performance, particularly when batteries are used as power buffers within larger systems. This paper presents an experimental analysis of the effects of cyclerelated degradation on the DCA performance of lead-acid cells. The
... esults show that capacity loss due to degradation does not provide a reliable indication of the cells DCA performance, in fact for the typical lifetime of the cell DCA performance remains broadly constant, independent of degradation. Only at very severe levels of degradation is DCA performance seen to appreciably reduce. The results show that the more rapid degradation of lead cells need not be such a concern in applications where DCA performance is key. The results also have implications for secondlife uses of cells in similar applications.
