Cycle life testing of a 24-V, 15-Ah sealed lead-acid aircraft battery

Abstract

This paper presents the results of cycle life testing of 24-V, 15-Ah sealed lead-acid batteries intended for use in the B-1B aircraft. Test samples were procured from two different manufacturers and subjected to cycle testing at 33% and 100% depth-of-discharge (DOD). The cycle life at 33% DOD ranged from 500 to 750 cycles. The cycle life at 100% DOD ranged from 160 to 260 cycles.
