Glossary: Battery Cycle Life

Battery cycle life refers to the number of complete charge and discharge cycles a battery can undergo before its capacity significantly degrades.

Expanded Explanation

Each charge-discharge cycle contributes to gradual battery wear. Cycle life is affected by battery chemistry, depth of discharge, operating temperature, and charge rate. Manufacturers often define end-of-life when capacity falls to a specific percentage of the original rating, commonly 70–80%.

Why it matters

Understanding cycle life helps predict battery replacement intervals and total cost of ownership.
