Base station lead-acid battery charge and discharge times

Base station lead-acid battery charge and discharge times

Simplified formulae for a battery cell discharge and recharge are: Discharge cycle. PbSO4 + 2H20 + PbSO4 → Pb + 2H2SO4 + PbO2. The lead acid battery uses the constant current constant voltage (CCCV) charge method. A regulated current raises the terminal voltage until the upper charge voltage limit is reached, at which point the current drops due to saturation. The charge time is 12–16 hours and up to 36–48 hours for large. . Sealed lead-acid (SLA) batteries are widely used in backup power systems, renewable energy setups, and more. With higher charge current s and multi-stage charge methods, the charge time can be reduced to 10 hours. . If we discharge the battery more slowly, say at a current of C/10, then we might expect that the battery would run longer (10 hours) before becoming discharged. [PDF]
