Batteries With Central Gas Venting

Batteries With Central Gas Venting


WARNING!
New style batteries with central venting system must be installed.
Original battery covers must always be used. The plugs must be equipped with an O-ring seal.


There are two types of batteries with a central venting system:
- Batteries with a hose or nozzle attached to the central venting system
- Batteries without a hose or nozzle attached to the central venting system


NOTE:
- The latest generation of batteries has a central venting system and a flashback protector in the form of a so-called "frit". Function: Gas produced when charging leaves the battery through a central opening on the top part of the side covering. A flashback protector is also integrated at the same place to prevent the combustible gas in the battery from igniting. The frit consists of a small round fiberglass mat about 15 mm in diameter and 2 mm thick. It works similarly to a valve, i.e. it allows gas produced in the battery to flow out.
- Do not grease battery terminals.
- Put the battery terminal clamps on only by hand, without forcing them, to avoid damaging the battery casing.


Notes regarding function of the central venting system:
- For batteries with hose/tube for central venting system, make sure the hose is not kinked. Only in this case can the battery be vented freely.







- For batteries without hose/tube for central venting system, make sure the opening on the upper cover side (arrow) of battery is not clogged.
