Leisure Battery.

Snailblazer

Hi, I've just spent a couple of days away in my 2003 Autosleeper Nuevo on a site with no hook up. Our leisure battery (85 amp/hr) is situated under the drivers seat and has a very small footprint, approx. 240 x 160 x 180cms high.  Having looked on the net,
I'm finding it difficult to find a correct size and capacity to replace it.  Has anyone else found a suitable replacement?
