Abstract

An automated battery test system determines the performance capability of an auxiliary battery used as a back-up power source for an electrically powered system in the event of a deficiency in a primary power source. The test system periodically isolates the auxiliary battery from the primary power source and tests at least one electrical characteristic of the auxiliary battery, without preventing the auxiliary battery from being immediately reconnected with the primary power source in the event of a need for a back-up. A multiple alarm arrangement generates audible and visual alarms in response to a detected failure of the auxiliary battery.
