Abstract

The invention relates to an entity (1) for testing a life-time of a battery (3) being an emergency electrical energy storage of an emergency lighting system (2), wherein the entity (1) is configured to perform the following testing steps: triggering charging of the battery (3) having a voltage smaller than a first voltage threshold (VT1), determining a time interval between a first point in time, at which the voltage of the battery exceeds the first voltage threshold (VT1), and a second point in time, at which the voltage of the battery reaches a second voltage threshold (VT2) being greater than the first voltage threshold (VT1), and determining a remaining battery capacity of the battery (3) using the determined time interval and an initial value of the time interval. Further, the invention relates to an emergency lighting system comprising such an entity and method for testing a life-time of a battery.
