充電器。 A voltage detection control means is provided for providing a reference voltage for comparison with the charging voltage of the battery to be charged, comparing the charging voltage and the reference voltage, and controlling charging based on the comparison result, and adjusting the reference voltage according to the ambient temperature. The charger is equipped with a temperature-compensating temperature-sensing element for correcting temperature compensation, and the temperature-compensating temperature-sensing element is disposed in a storage section provided separately from the charger main body case, and the storage section is arranged in a storage section provided separately from the charger main body case. The battery is isolated from the main body case by a heat insulating material, and the temperature-compensating temperature-sensing element is disposed at a position where it is not affected by temperature changes inside the charger and is affected only by the ambient temperature of the battery to be charged. charger.
