78. Deep Discharge Of Lead-Acid Batteries Explained

Battery manufacturers specify the end-of-discharge voltage based on battery design and application. Any discharge below the end of the discharge voltage is termed a deep discharge. Deep discharges, especially when more frequent, lead to battery capacity loss and degradation of the active material. Batteries subjected to deep discharges fail prematurely. In the case of lead-acid batteries, deep discharges damage both the positive and negative electrodes. Sporadic and infrequent low volt...
