A method of charging a rechargeable battery, and a protection circuit for the rechargeable battery. The protection circuit perceives whether the battery is charged or not by sensing the voltage of the bare cell, changes the direct voltage applied between a gate electrode and a source electrode of a charging field effect transistor, which is installed between one terminal of the bare cell and one terminal of a charger in series, and controls the amount of the current flowing from the source electrode of the charging field effect transistor to a drain electrode at a low level, thereby to maintain a low charging rate of the battery. |
