A battery protection device may include a thermally responsive operating plate having two plates secured together, the two plates having different coefficients of thermally expansion, an electrically conductive member, and a stopper with which the thermally responsive operating plate can be interlocked. The battery protection device may have a recoverable region current cutoff state, where the thermally responsive operating plate is not interlocked with the stopper, and a contact and dissociation of the thermally responsive operation plate with and from the electrically conductive member can be repeatedly realized. The battery protection device may have an unrecoverable region current cutoff state, where the thermally responsive operating plate is interlocked with the stopper and the thermally responsive operation plate is unrecoverably dissociated from the electrically conductive member.
