Abstract
The electronics comprises a load circuit, a power supply circuit having a rechargeable electrical energy storer, and a protection circuit. An input of the power supply circuit is adapted to be electrically connected with an external energy supply. Both the power supply circuit and the protection circuit have at least two operating modes. Additionally, the protection circuit is adapted in the first operating mode to monitor the cell voltage applied on the circuit input to determine whether its voltage level has exceeded a predetermined maximum value and, in given cases, automatically to deactivate the operating mode.
