Have you load tested battery ? Have you checked altrnator output ? If so and all o.k , you will have to test for a parasitic drain .

Hi,yes ive had the battery,alternator and starter motor,tested.there all fine,whats a parasitic drain?

Parasitic drain is when something slowly drains the battery!!!!.
Have you checked to make sure all the lights go out, including the boot light and glove compartment light????...
