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 that the central venting hose or tube is always secured on the battery.
- Ensure that 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.
