ABSTRACT:
A battery charging circuit includes a thermostat for sensing the temperature of the battery as it is charged, a silicon controlled rectifier which when conductive enables charging of the battery and when non-conductive prevents charging of the battery, and a transistor for preventing the silicon controlled rectifier from returning to the conductive state after being switched to the non-conductive state. When the temperature of the battery reaches a predetermined level corresponding to complete charging, the thermostat switches the silicon controlled rectifier to the non-conductive state and enables the transistor to be turned on to prevent further charging of the battery after the temperature thereof falls below the preselected level.
