OK,
Before I go and spend £50 on an Optimate 4 I need to ask will it be worth it?
2 x 110 AH leisure batteries 3 years old, nearly always on EHU when camping. Now sitting in garage and will charge and be at 13v ish just after charge. Within 24 hours have dropped to 12.46 (50%?) and will stay at that for days on end. So it looks like all cells are OK, batteries DO charge so I'm thinking sulfonated, hence Optimate.
All your wise comments appriciated.
