Information

State-of-the-art batteries have central venting -A- .
The gas generated during charging emerges centrally through an opening on the upper cover side. The backfire protection is integrated at the same position, which prevents the ignition of the combustible gas present in the battery.
For batteries with a hose/pipe -A- for central venting, check that the hose is not disconnected or pinched. Only then can the battery be freely vented.
