Abstract
A method of testing the battery of an uninterruptible power system by changing the priority of the battery to make it a primary, rather than secondary, power source. This allows the battery to be tested in a fail-safe mode such that a battery failure during the test will not cause any interruption of power to the inverter and thus the load.
