Abstract
A method and an apparatus for determining the battery level of a rechargeable battery used in a battery driven apparatus for driving a load and for indicating a low battery level; and a repeating measurement of the battery voltage and a determination of a threshold for indicating the low battery level. The running time of the apparatus while driving the load is accumulated since the last charging and is repeatedly stored as sequenced data-logger entries in a data-logger memory until a reset of the apparatus due to insufficient battery capacity or until charging of the battery. Threshold is determined after the reset based on the data-logger entries and a required remaining running time of the apparatus upon indication of low battery level.
