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), andreporting a battery failure when said sensed value is outside said range.
