PROBLEM TO BE SOLVED: To provide a battery charger capable of completely charging a battery without danger of ignition and explosion when charging a sealed battery such as a lithium ion battery, resulting in a reduced cost load of a user.SOLUTION: The battery charger includes: battery charge means for charging a connected battery on the basis of predetermined charge algorithm; and signal analysis means for analyzing the battery on the basis of a charging signal transmitted from the battery charge means. The battery charge means repeats charging for a predetermined number of times while automatically switching the charge algorithm according to a battery state analyzed by the signal analysis means. |
