Right so it looks like I need a new battery on the S3. Over the last week or two I've had a few issue with the battery struggling to start the car and then this evening it wouldn't start. I've checked the battery with a voltmeter and it's ok when running, somewhere around 13.5-14 volts, but it dropped down to 9.7 volts when switched off.
So my question is, any recommendations on what to get and where from?
