This invention relates to a multi-cell storage battery including a housing and, enclosing the housing in gas-tight fashion, a housing cover assembly having an upper cover panel and a lower cover panel with a degassing duct between the upper and lower cover panels which encompasses a multiple array of interconnected, mutually matched labyrinth chambers, fluidically links all cells, opens out at a forward end into at least one gas vent, and is closed off by a spark suppressor. To arrive at a storage battery in which adequate degassing is assured under all operating conditions while at the same time any leakage of acid accumulated in the degassing duct is largely prevented even when the internal pressure is high, the invention proposes a design whereby the gas vent is positioned at an essentially perpendicular angle relative to the direction of gas flow through the spark suppressor while in the area between the spark suppressor and the gas vent the degassing duct is provided with a widened section forming a collecting chamber which, when the storage battery is in its normal position, is situated underneath the gas vent.

Multi-cell storage battery with gas vent in a cover assembly

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.
