The charging method directly determines the service life of lead-acid batteries. Avoid overcharging and undercharging strictly in daily use. Use only dedicated chargers matching the battery’s rated voltage and parameters, and never use mismatched high-power chargers. Charge the battery in a cool and ventilated environment at 15-30℃, avoiding direct sunlight, high temperature and severe low temperature. The optimal charging time is when the remaining power is 20%-40%; do not exhaust the power to prevent plate sulfation. Cut off the power in time after full charging and avoid long-term floating charging. Do not overcharge overnight. Appropriately adjust the charging duration according to seasons to slow down battery aging.
