Central Venting System

Maintenance-Free Batteries

Only maintenance-free batteries conforming to standards "TL82506 " (as of December 1997) and "VW75073" (as of August 2001) may be installed.

CAUTION!
Risk of injury due to contact with battery acid!

• Prior to handling or servicing batteries, read, understand and observe the Warnings and Safety Measures => [ There is a risk of injury from the battery
acid. ] Battery.

Risk of explosion due to the explosive gas that forms during battery charging.

• Observe warning notes and safety precautions => [ Risk of explosion due to the explosive gas
that forms during battery charging. ] Battery.

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.

• 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.
