You're sure that hubby's battery is ok? Borrow a bettery of a willing friend or neighbour and see if that's the same.

Check that the alternator belt is tightened to the right spec then, after that all I can suggest is that you go to an auto electrician to have your alternator checked and also check for any unwanted drainage issues.

hubbys battery was good the belt is nice and tight but will get the alt checked thanks for the help

Sounds to me like you have a power leak some where, does your boot light stay on when boot is shut, if the battery wasn't charging you would have an alternator lamp on on your dash so you basically have quite a current drain some where could well be a auto electrician job to find it I mention the boot as some of the early Renaults (Megane/Scenic) suffered this problem, electrics not my strong point but it looks to me car is ok whilst running but drians when left alone or over night so it looks like a power drain.
