Abstract:
1. An arrangement for testing a battery connected to a battery charger and a work load, said arrangement comprising: first conductor means for connecting the battery to the battery charger and work load under normal operating conditions allowing the battery to drive the work load and the battery charger to charge the battery; second conductor means coupled in parallel across said first conductor means, wherein said second conductor means is nonconductive under normal operating conditions; user selectable means responsive to an input for initiating testing of the battery; and control/detection means coupled to said first and second conductor means and to said selectable means for conducting a battery test, wherein said control/detection means renders said first conductor means nonconductive and said second conductor means conductive during a battery test for isolating the battery from the battery charger while permitting the battery to continue to energize the work load during testing, and wherein said control/detection means applies a test load across the battery for measuring battery voltage during testing.
