Just a quick one, I seem to have trouble with cold starting my S3, dont know whether it is just a weather thing or whether my battery is on its way out. Had it tested at Kwik Fit and they said it was fine and was charging, but the problem still remains. On a cold morning, it feels like the car has been sat for weeks. Was just wondering your thoughts on this or whether I should be changing the battery for somethign a bit more powerful? Thanks in advance.
