I've been on holiday for a couple of weeks and have had the GTV tucked up on the drive. When I tried to start it up after I got home the starter motor turned over but too slowly to fire the engine. I figured the battery was low, so I put it on charge overnight using my CTEK smart charger.
Next day I saw the charger had got up to stage 4 and the error lamp had lit up. Reading the manual it says the charger is indicating that the battery will no longer hold a charge as well and may need replacing. I then unplugged the charger and tried to start the car. It did start but it still struggled to turn over.
So it looks like I will be needing a new battery. Do you have any advice on which one to buy, what capacity am I looking for? And as I will not be using the GTV as regularly over the winter would a bigger capacity be better?
