A system for determining an indicator of an internal leakage current of a battery entity includes a voltage meter configured to be coupled to the battery entity and to measure a plurality of voltage values corresponding to the battery entity at a plurality of time instants. Further, the system includes an isolator configured to be coupled to each of a battery charger and an electricity consuming entity, as well as to electrically isolate the battery entity from each of the battery charger and the electricity consuming entity based on a control signal. Yet further, the system includes a controller electrically coupled to each of the voltage meter and the isolator the controller being configured to determine the indicator of an internal leakage current based on each of the plurality of voltage values.
