After 6 months of using the carpc, my battery has taken a serious raping, to the point where the car wont start in the morning now, bear in mind the batteries cost 100 quid for the Audi.
I had a new battery fitted in june 2002 by the AA and paid the driver for it, all fine and worked well up till now, it just dies overnight, so I phoned the AA even though im no longer a member as my insurance at the time used AA I now use greenflag, after a convo with a women at breakdown she said " yes that battery has a 3 year warranty I will have an guy to you in an hour" and in 1 hour a guy came along with a brand new spanking 100amp battery, removed my old one, car starts on the button and everyones happy.
So even though i'm no longer a member they still warranty and fix on site all there faulty equipment, excellent service I must say.

PS if you use an invertor in your car make sure you buy a DEEP CYCLE battery, thats my next purchase
