Abstract

The invention relates to a rechargeable battery with a battery housing having a rear wall with a recess which extends as far as an end wall of the battery housing and has a base side and narrow sides facing each other, the base side continuing via a step into the outer side of the rear wall, and a contact assembly which is covered by a cover extending from the step being positioned at the step. In order to further develop the battery so that when the battery is connected to an electrical appliance the contact assembly is protected against splash water, it is proposed, in accordance with the invention, that the cover form a contact housing which completely surrounds the contact assembly in circumferential direction and has on its side facing away from the step an insertion opening surrounded by a circumferential rim of the contact housing, which forms a sealing surface.
