Abstract

A lead accumulator has a housing with a frontside, a backside, a first and second end faces, and a bottom. The housing has a plurality of cells containing acid. A lid is provided for closing the housing. The lid comprises an upper lid and a lower lid spaced from the upper lid to define a space therebetween. The space is divided by chamber walls into a plurality of chambers such that each cell has a corresponding chamber within the lid. For each cell the lid has a fill and check opening closable by a stopper. Each chamber has guides for controlling the flow of acid. The guides comprise deflecting stays and an annular stay surrounding the fill and check opening, the annular stay having a degassing and return outlet. The lid further has at least one ignition protector. The guides are designed and arranged such that, in any position of the housing, when resting on one of the side walls, acid within the chambers remains below a level above which acid flows into the ignition protector.
