A charge control device has a full charge detection circuit for checking whether a secondary cell is in a fully charged state or not based on the charge voltage and/or the charge current of the secondary cell, a control circuit for controlling the feeding of electric power to the secondary cell according to the output of the full charge detection circuit, a storage circuit for storing control information, and a setting circuit for setting the level of the charge voltage and/or the charge current at which the full charge detection circuit recognizes the fully charged state according to the control information read from the storage circuit. The control information is fed into the storage circuit from outside. With this configuration, it is possible to accurately control the charging of a secondary cell by canceling the influence of stress occurring when an IC is packaged or mounted on a circuit board and other factors.
