Abstract:
1. A battery test circuit, for testing batteries in a working circuit having a plurality of batteries and a load, said test circuit comprising: a DC step up converter having an input at a first voltage and an output at a second voltage higher than said first voltage, that may be selectively interconnected between a first one of said plurality of batteries and at least one second one of said plurality of batteries to cause said first battery to supply a defined test current and deliver a current from said output to said at least one second one of said plurality of batteries; an indicator output, for providing a signal indicative of whether said first battery provides said test current, substantially at the rated voltage of said first battery; a plurality of input switches, each one of said input switches for connecting a corresponding one of said plurality of batteries to said input of said DC step up converter; and a plurality of output switches, each one of said output switches for connecting a corresponding one of said plurality of batteries to said output of said DC step up converter.
