The present invention relates to a bipolar battery provided with a pressure sensor. The battery is provided with a housing 7 containing common gas space 97. The pressure sensor 10; 20; 50; 63; 80; 111 comprises: an actuator 3, 21; 31; 41; 48; 81 configured to transfer an internal pressure P within the common gas space to a reciprocal movement, and a switching device 5; 83 configured to generate a control signal indicative of changes in relation to an initial switching state generated by said reciprocal movement when the internal pressure exceeds a predetermined upper level. The pressure sensor further comprises a reset means 4; 32; 81 to automatically reset the switching device to the initial switch state when the internal pressure goes below a predetermined lower level, whereby said control signal is based on the internal pressure (P) within said sealed common gas space. The present invention also relates to a method for charging bipolar batteries.
