PROBLEM TO BE SOLVED: To provide an electronic apparatus and a charging method that perform charging in safety even if an AC adapter is equipped with a charger of a secondary battery that has been equipped to the electronic apparatus. SOLUTION: A charging mode is falsely brought into a state of a pre-charging mode of the secondary battery E1 by a false battery circuit 5. If the AC adapter 1 is provided with a charging circuit, power corresponding to battery characteristics of the circuit is fed. An operation-confirming circuit 6 for the charging circuit thereby determines whether the power is suitable for charging the secondary battery E1, and only when the power is determined suitable therefor, a switch circuit 4 is turned on, thus charging the secondary battery E1.
