Abstract
A battery charger charges a discharged battery and can be connected directly to an appliance where it serves as an AC adapter. The output of the battery charger automatically reduces to a trickle maintenance charge as the battery approaches a full charge condition. A Zener diode, used for overcurrent protection automatically turns off the charging function in the event of an overcurrent condition. The circuit automatically resets when the overcurrent condition is removed. A hinged section, when opened out, provides mounting for a battery to be charged. When the hinged section is closed, switches are operated, and electrical connections are made to permit affixing the charger, as an AC adapter, to the normal battery retainer of the appliance.
