Hi, I have just had a similar problem, i bought a brand new battery in jan 09, no problems until now, dec 09, went away for a week and left my car at the airport, got back, jumped in and dead battery, just a bit of clicking from the starter then nothing, it was cold the week i was away, -2 to +4deg, surely this shouldnt happen, could it be a duff battery or maybe the altinator isnt putting the correct amount of charge in when im driving, also somebody mentioned to me that i might have a drain on the system, ie. something not shutting down and using a small amount of power even when the car is off and locked, it does have dvd and tv in but only powered when ignition is on although they do have memory power, wouldnt have thought that would drain the battery too much tho, any advice would be very helpful, thanks
