On a Westfalia. I have checked the battery, and it is very low - 5volts or less. So I checked the charging using a draper tool, and charge is reaching the battery. The battery looks old, so I guess its knackered - could explain why the Eberspacher burner doesn't light, and why the fridge seems a little dead lets say.
So - I need to replace it - yes? Two questions:
1. Recommendations for a good leisure battery? (make and outlet?)
2. How do you remove it!! There is no way I can get it out because of the seat metal base, even swivelling the seat round. So I think the whole seat is gonna have to come out

. Looks like just four nuts to undo right? Can anyone give me a step by step idiots guide to removing the seat to get at the battery. You are dealing with a novice btw!
Many thanks
