Can you decipher this on my Leisure battery please?

To save on powering the fridge, we place a 2ltr container of ICE in it before a w/e away. There's often still ice in it when we come home!!

Also, I've inserted a small thermometer in the front of the fridge

 

Cheers for all your help Matty, I took the LB in today and the guy recons it's knackered. He's going to charge it on his machine for 48hrs but I've started looking for a new one.
Good tip about the wire size. I may get bigger wires from the battery to the fuse box as well while I'm messing about in that area.

 

I like the thermometer idea Mike. Unfortunately we're nowhere near organised enough for the ice trick. Most of our trips away in the van are pure spur of the moment ideas. Get milk, get bread, get going!
