ABSTRACT:
A battery charger for charging a secondary battery has an infrared radiation sensor for detecting the surface temperature of the secondary battery while the secondary battery is being charged. A charging control circuit stops charging the secondary battery, typically an Ni-MH battery, when the surface temperature detected by the infrared radiation sensor has reached a predetermined temperature. The battery charger also has a potential detector for detecting an electric potential of the secondary battery. The charging control circuit stops charging the secondary battery, typically an Ni--Cd battery, when the electric potential detected by the potential detector starts dropping after the battery has fully been charged.
