The depth of discharge parameter determines the percentage of the energy storage system that be considered usable for the system design. The depth of discharge value chosen affects the capacity, cycle life, and cost of the energy storage system. Lead acid batteries are not tolerant of regular deep discharges, thus values between .4-.5 (40-50%) are typically used. A value of .5 is often cited as providing the highest number of cycles relative to cost, but there are additional considerations that should go into determining the depth of discharge value:
