I say 10 days as op said 10 days
Have you an ampmeter? You could then test what amperage is being drawn with everything turned off. screwfix do one that is not too expensive
even new batterys can be faulty, had one a coupe of years ago from Halfords but they changed it no problem

Had the same experience. Yuasa battery failed after 10 months. Halfords replaced it after testing it under warranty. But I wasted a lot of time checking everything before I finally realised my 'new' battery was faulty.
