I recently bought two new leisure batteries for my Autosleeper Kemerton XL. The existing batteries are located underneath the sofa/bed in the lounge , and are vented via a tube through the bottom of the van. The tube is connected to the battery with a L shaped plug (a bit like a jack plug) that is circular in cross section - so round peg in round hole.
My new batteries have a square vent hole, which the round plug won't fit into. I've googled extensively, but can only find round plugs, and no mention of anyone else having a similar problem. I know that I'm special, but I can't be that special!
The batteries are Numax CXV30HRMF Sealed Leisure Batteries, which I bought from Tayna (who can't offer any solution). I've also emailed the manufacturers, Ecobatt, but haven't had a response as yet.
Any thoughts appreciated. I've installed the batteries without the vent tube, but I'm obviously slightly concerned as they are sited in the habitation area. The vent hole is about 1cm wide by about 0.5cm high
