PROBLEM TO BE SOLVED: To provide a battery charger which can watch a source voltage condition under charging and easily correspond to an overcharge and an insufficient charge and a battery forklift installed it. SOLUTION: The battery charger comprises a voltage sensor (12) which detects the voltage of the external power source and/or a current sensor (13) which detects the power source current and a battery charge control equipment (11) to which the detected voltage value and/or current value are inputted, and which can indicate the input data. The maximum and/or minimum value of the power source voltage and/or current under charging are obtained from the input data, and stored in the battery charger. The stored data can be also displayed. The generation time of the maximum and/or minimum value is stored and can be also displayed. The input data is stored with its time data, and can be also displayed after reading out the stored data by the external readout signal. |
