Abstract

A rechargeable battery includes a housing, a plurality of cells within the housing, and a cover which closes the housing. The battery also includes a plurality of filling openings arranged in the cover separated from one another by a distance and a plurality of plugs. Each of the plurality of plugs is configured to close one of the plurality of filling openings. A flexible connecting element connects at least two of the plugs. The flexible connecting element is configured such that the distance between the plugs which are connected to one another can be variably matched to the distance between their associated filling openings by rotating at least one of the plugs connected by the flexible connecting element.
