Several box-shaped receptacles (100a) form a perfect fluid-tight and gas-tight chamber when nozzles (108c) of a tubular pipe (108) are projected towards the inner side of the box-shaped receptacles. The tubular pipe crosses the ramp and communicates with inside of a battery through several plug units (104) that maintain sealing engagement with the openings of the battery top wall. |
