On my Hymer there are two leisure batteries, one under the passenger seat and one under the drivers seat... plus one I had fitted under side bench, all three bought together with the same output and fitted by a Hymer dealer in Huddersfield..
It would be strange for there not to be a habitation battery, maybe a previous owner took it out to save buying a new one, which would make him "daft like brush!"..
Maybe but he has left no sign of cabling or holes or ANYTHING
Think i will just use that space under the passengers seat and add a battery or two
Yes under the font drivers seat. (LHD) I think I will just do a fresh install. Take out the passengers seat and put them there. Have a 3kw Victron in the compartment through the wall so that is handy. Have looked everywhere for the second battery or signs as to where it EVER was. Nothing..Thanks guys for your help.
Well here is what I found .Can onlt assume they are well past being of any use as previous owner did not think it had any. Do those codes mean anything. Would be interesting to date them. Put two 120AH in there and they fit
