I've had this checked this morning and a dud battery.
Charging fine but discharging really fast.
Only got it in October from Eurocarparts (Lion Battery (027 Battery - 3 Year Guarantee)
Phoned ECP and they say can't get refund/replacement without receipt even though I have order email
i had a new battery and alternator fitted around 6 months ago and car has been fine since (A3 TFSI 2.0 2006)
Today the car failed to start and no electronics would work
After jumpstarting and driving around 20 minutes everything seems ok but i want to know why this could happen.
