ive got a 75ah battery on it at the moment from a mondeo derv , although i think i may have accidently found the problem , ive used the car today in agin it was lazy to start but did. ive lent my head unit to a friend and it's flattened his battery on his scooby in under 6 hours all with the car sitting locked up . and lone behold the saph turns over really well, so i'll leave it out a few days and see how it goes . Cant understand why it's not showing a high drain on mine but it is on his ?
