Battery Conditioning Question

[jez_anderson]

I have a battery conditioner from carcoon, but its basically the same as the rest. I have the lead that can be permenantly connected to the battery connected.

When I have left it on before I have fed the cable through a part open window and had no problem with the alarm going off.

Since a change of car and a change of immobiliser this no longer works as the alarm has gone off, I assume because of the open window and the alarm detecting something.

I thought of putting a small hole in my indoor car cover to pass the cable through to see if that would allow me to leave conditioner on without the alarm tripping. Obviously with the window being partially open under the cover.

But

Does the battery need ventilation whilst being conditioned? Will what I am suggesting be a problem in terms of the battery and no ventilation?

Or

Am I worrying about nothing? Any suggestions how to overcome the problem?



Thanks

Most modern batteries are sealed, so you don't need to worry about ventilation.

The 944 battery has a pipe to route any overflow or vapour out the bottom of the wheel-well. I don't know how thick the cables on the Carcoon one are, but my Halfords one with a standard sort of 13amp flex on it is quite happy being shut in the hatch seal.

I've got the Carcoon, the cables are really thin and have no worries fitting over the hatchback rubber seal. I just make sure I shut it in a different place each day to stop the rubber getting kinked

I used to shut mine in the bottom of the door when I had a 944. Likewise it used to fit through no problem.

In the centre just above the boot lock is where the two ends of the seal should meet, there is usually a small gap here that the cable can be passed through.

Although sealed they can still vent hydrogen under certain circumstances, We use very expensive (120each) sealed batteries at work and even those can vent hydrogen if too much current is applied.
