Yep I feel like a complete idiot, thinking that all cells in my battery were linked I topped up one after the battery was acting weak and having to call the AA two weeks ago for a start, decided to check today and the other five cells were very low, so after 1.75 litres of distilled water later, looks like it's topped up again, zero maintenance batteries my ar$e!!
Don't forget to check em before the cold starts ladies n gentlemen.
