2007 Van battery going flat after a week of no use. Is it normal or indicating new battery in order?

Battery isolator seems a good way to both stop wasting this electric and also doubling up as a security feature from what I am seeing, which is also something I had wanted to do as I have been getting big anxiety any time I left my van due to living in it so stakes are high.

This looks like what you should have? I don't know much about living in a van, but your battery is important.

EnPointe

2007   vehicle ? when was the Starting battery last replaced ?  if it's the original battery  it's likely   become tired, sulphated and all the  other age  related degradation you see with lead-acid batteries ? 

even if the battery has bene replaced once unless it  was replaced in the past  few years it may well have beomce degraded with age  ( if it was replaced at 7-10 years  it  between 7 -10 years old ) 

I note you say you are livign i nthe van  ., what is the arrangment of bartteries, charging  and  are the house batteries adeuqately isolated fro mthe Starting / vehicle battery ?   

is there a quiescent load on the starting  battery ?
