Abstract
A storage battery-based DC power supply system with continuous float charging adapted to automatic continuous recharging of storage battery connected to load is disclosed. Selective recharging at the full-charge voltage and float charging voltage is performed in response to the accumulated ampere-hour value of discharge current from the storage battery, when such value reaches a predetermined threshold value set to prevent excessive recharging, which can damage storage battery.
