"Discharge cycles" refers to the number of times a battery is fully used and then recharged. It represents how many times you can use the battery before its capacity to hold a charge diminishes over time. Full definition
The batteries would also need to have at least 1,000, and preferably 1,500 charge - discharge cycles without showing a noticeable power or energy storage capacity loss. (sciencedaily.com)
Not only did the batteries work and with a consistent capacity, but they were able to go through 60 charge - discharge cycles with just a small decline in capacity. (treehugger.com)
The cell chemistry and single, highly complex cooling circuit must cope with recurrent full discharge cycles. (automobilemag.com)
