TT Quattro Roadster V6-3.2L (BHE) (2005)
Battery: Description and Operation
Central Venting System
Central Venting System
To prevent vapors produced by the battery during charging from causing damage or posing a health at risk, vapors are discharged centrally through an
opening on the top cover side of the battery.
-
Ensure the central venting hose or tube is always secured on the battery.
-
Ensure the central venting hose or tube is not pinched. Only then can battery be properly vented.
Note: Newer generation batteries have a fine mesh flame trap at the central venting exit point. The "flame trap" is a round fiberglass matt approximately
15 mm wide and 2 mm thick that works like a valve. On the one hand, it allows the gas formed during battery charging to flow out and on the other
hand, prevents the explosive gas in the battery from igniting.
