Abstract
A battery includes a housing, at least one individual cell arranged in the housing and including at least one positive electrode and at least one negative electrode, a positive pole stud passed through the housing and electrically connected to the at least one positive electrode and/or a negative pole stud passed through the housing and electrically connected to the at least one negative electrode, at least one electrical switch which can be pneumatically operated and changes its switching state in the event of an increase in pressure within the housing beyond a threshold value and thereby interrupts the electrical connection between at least one of the pole studs and an associated at least one electrode, and a resetting device with which an electrical connection which is interrupted as a result of a change in the switching state can be re-established without the housing having to be opened.
