Abstract (en)

[origin: WO9908360A1] The invention concerns a stand-by battery consisting of an accumulator for ensuring the standby supply of a circuit, in service voltage, coupled with an electrically irreversible element constituted by a fuse, to form a unit. If said irreversible element is its initial state at the time of query, it shifts to its irreversible state and said time is memorized. By fixing without ambiguity the first operating time of the stand-by battery, a change of battery which appears to be required for security reasons before the guaranteed lifetime expires, can be avoided. In a particular embodiment, the irreversible element indicates the time when the stand-by battery reaches the end of its lifetime.
