Batteries with central gas venting system
Attention:
Batteries of latest design with central gas venting system are always to be fitted.
Always use genuine battery caps. The caps must be fitted with an O-ring seal.
There are two types of battery with central gas venting system:
◆ Batteries with hose/connection at central gas venting system
◆ Batteries with no hose/connection at central gas venting system
Notes:
◆ The latest generation of batteries features a central gas venting system and a fine-mesh flame trap.
Function: The gas produced on charging escapes centrally through a hole in the top cover. The fine-mesh
flame trap which prevents ignition of the flammable gas in the battery is also located here.
