High C-rate operation increases internal polarization, heat generation, and electrochemical stress, which directly shortens battery lifespan if used continuously. Battery capacity is usually measured under low discharge conditions (0. . For battery buyers, engineers, and system integrators, misunderstanding C-rate often leads to premature battery failure, unexpected safety risks, and rising lifecycle costs. This technical blog provides a deep, engineering-level explanation of how discharge rate affects battery performance, aging. . The depth of discharge (DoD) is a critical factor that significantly influences the lifespan of a lithium battery pack. Following battery manufacturers' recommended DoD limits and balancing DoD with battery cycle life is essential for maximizing the efficiency. . Every Li-ion battery has a manufacturer-specified maximum continuous discharge C-rate (e.
