Abstract: A battery pacer apparatus and method are configured for extending the life of lead-acid batteries. A high current discharge is applied for a limited time of about 10-40 seconds to remove lead sulphate deposits on the electrodes. Following discharge, the battery is fully recharged. The pacing discharge is initiated at least about once daily by a timing circuit. During the pacing discharge, the battery voltage is measured. A decrease in battery voltage to below a preset non-steady state failure value is indicative of imminent battery failure, setting off an alarm enabling replacement or servicing before the battery fails in service.
