Abstract
A process for performing an auto-test of a fully discharged battery () of an electronic appliance including a battery charger (), said process involving the steps of: performing () an initialization phase; charging () said battery () with a predetermined constant current during a predefined period allowing stabilization of said current (Icurrent); detecting () the voltage of said battery after said predefined period, said battery being still in charge; testing () whether said sensed voltage is comprised within a predetermined range of threshold values (V1, V2), and reporting a battery failure when said sensed value is outside said range. The invention is particularly adapted to the auto-test of a backup battery made of Electric double layer capacitors or any fully discharged backup battery.
