Battery is inserted correctly when center cut-out in battery foot strip aligns with threaded hole in battery carrier -arrows-.

On batteries with a hose for central venting ensure that the hose is not squashed. Only then can the battery vent freely.
On batteries without a hose for central venting ensure that the opening on the upper side of the battery cover is not blocked.

NOTE: New generation batteries are equipped with a central gas venting system and integrated flame trap. Function: Gases produced during charging escape through a central opening on the side of the upper cover. The integrated flame trap prevents flammable gases in the battery from igniting. The flame trap is comprised of a small round fiberglass mat with a diameter of 15 mm and a thickness of 2 mm. Working as a one-way-valve, it allows gases produced during charging to vent.
