ABSTRACT:
A test circuit for a back-up battery includes a main switch which connects a main power source to a load, and a diode which is interposed between a back-up battery and the load. The diode is reversed biased when the main power source supplies rated power to the load. To test the battery, the main switch is turned off such that the back-up battery supplies operating current to the load via the diode. During a test interval, the output voltage is monitored to determine if the battery is able to supply its rated voltage under load. After the test or if the battery fails to supply requisite voltage, the main switch is turned-on again.
