The end of life is usually considered when the battery capacity drops to 80% of the initial value. For most lead–acid batteries, the capacity drops to 80% between 300 and 500 cycles. Lead–acid battery cycle life is a complex function of battery depth of discharge, temperature, average state of charge, cycle frequency, charging methods, and time.
The service life of a lead–acid battery can in part be measured by the thickness of its positive plates. During charging and discharging, the lead on the plates gets gradually consumed and the sediment falls to the bottom. As a result, the measurement of the plate thickness can be an indication of how much battery life is left.
The B (1) life of the lead-acid battery is calculated as 1157 cycles. It infers that when the lead-acid battery completes 1157 cycles, there is 1 % chance that the lead-acid battery fails. In other words, from a given lot of lead-acid batteries, 1 % batteries will fail at 1157 cycles, indicating an early failure.
Lead acid batteries typically have coloumbic efficiencies of 85% and energy efficiencies in the order of 70%. Depending on which one of the above problems is of most concern for a particular application, appropriate modifications to the basic battery configuration improve battery performance.
A true measure of a battery’s life-cycle performance is the amount of service rendered — in this case, lifetime kilowatt-hours delivered. For example, the total life-cycle energy of a battery (LCEbat) in a particular application is dependent on the expected lifetime service demand (kilowatt-hours) and battery properties. More specifically:
Even though the CTF is the appropriate way to measure the life of the lead-acid battery, it is a time-intensive test to get CTF data. In this view, a limited sample, four lead-acid batteries (namely B1, B2, B3, and B4) commonly used in e-rickshaws were tested on the fast-charging experimental setup.

What is Battery Cycle?
Generally, lithium-ion batteries, which are commonly used in smartphones and laptops, are designed to handle around 500-1000 cycles, while lead-acid batteries, used in automobiles, can handle around 200-300 cycles. As the number of cycles increases, the battery''s capacity to hold a charge gradually decreases, resulting in shorter battery life.
