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.
Such batteries may achieve routinely 1500 cycles, to a depth-of-discharge of 80 % at C /5. With valve-regulated lead–acid batteries, one obtains up to 800 cycles. Standard SLI batteries, on the other hand, will generally not even reach 100 cycles of this type. 4. Irreversible formation of lead sulfate in the active mass (crystallization, sulfation)
The Eq. (5) is used to describe the B (x) life of lead-acid batteries, where p is the failure probability and γ is the respective hazard rate . (5) B x p = γ + θ − ln 1 − p 1 / β The B (1) life of the lead-acid battery is calculated as 1157 cycles.
The lead–acid battery is an old system, and its aging processes have been thoroughly investigated. Reviews regarding aging mechanisms, and expected service life, are found in the monographs by Bode and Berndt , and elsewhere , . The present paper is an up-date, summarizing the present understanding.
One of the most important properties of lead–acid batteries is the capacity or the amount of energy stored in a battery (Ah). This is an important property for batteries used in stationary applications, for example, in photovoltaic systems as well as for automotive applications as the main power supply.
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.
