PURPOSE:To find how many times a battery charger is charged from the outside readily and to discriminate whether the fact is the repeating life or the fault other than the repeating life readily even if the fault has occurred. CONSTITUTION:A counting circuit 2 counts the signals inputted through a third terminal T3. The charge-completion signal is inputted through the third terminal T3 from a charging device 4 which is externally connected. Therefore, the counting circuit 2 accumulates and counts the number of the charging times of a battery charger 1. The counting circuit 2 has the reserve battery, and the counted result is maintained even if the battery charger is excessively discharged. The counted result of the counting circuit 2 is inputted into a display device 3, displayed as the number of the charged times and notified to an operator. |
