Our CM alarm goes off just in the van we have just bought Coachman (18 months old) but we have replaced the alarm with a new one assuming faulty and it is is going off again despite nothing that could set it off….

I have seen online that leisure battery issues can cause this ?

Anyone have experience of this ?

Not sure I like that idea Davy even if they are gels. Don't they have vents as well even though they don't need any maintenance/topping up?

Thank you for your suggestions

we have removed cm detector and it stops as soon as outside van so we know it’s something in van triggering it 

I think we need to check leisure battery health as this must be the source.

It may be the case that UK built vans are vented outside but the 3 german vans I have owned all have had the batteries installed indoors. Does the fact that they are gel batteries make any difference?

As far as I can see they are simply mounted below a seat. The current  van a Hobby has the battery in a plastic  box,certainly  not sealed or vented.  The Hymer didnt even have a box of any sort. If there is any ventilation it may be holes in the floor but I would assume the fumes rise.

Our last Bailey had the battery under the floor inside the van and was in a sealed box (well it had a rubber seal around the lid).  It was difficult to see, but there was, in fact, a small rubber pipe passing through the floor to the outside to vent it.

Mine is forever chirping at me to say it needs a new battery which never seem to last five minutes. Connecting to the 12v circuit would be nice instead of forever buying new Duracells.

David,  Your battery whether a basis wet, gel, or AGM must be vented to the outside world.  Normally if fitted inside they have a small tube fitted to one or more holes in the end of the battery venting to the outside.   

PS. who is Pedro 😁.
