The 12V120Ah medium-low density energy storage lead-acid battery features a long cycle life and is suitable for solar energy storage and industrial equipment backup power. Maintenance is crucial for daily use. The operating environment must be dry and ventilated, away from moisture and corrosive gases to prevent internal short circuits. The discharge termination voltage should be ≥10.5V; over-discharge is strictly prohibited as it slows capacity recovery. Adopt two-stage charging: first constant current at 12-24A, then constant voltage at 13.5-13.8V, and float charge when fully charged to avoid electrolyte decomposition caused by overcharging. Regularly check for leakage or bulging, apply petroleum jelly to terminals to prevent oxidation. Store fully charged when not in use for a long time and charge every 3 months to ensure a 12-year float life (20℃).
