The battery for my 2002 C240 Petrol (W203) is knackered and I'm trying to source a new one. I've put the car reg onto various sites and they're throwing up all sorts of options. Unfortunately, the bonnet is stuck so I can't verify the correct dimensions to ensure the new one would be a perfect fit. I'll be grateful if someone could advise on the right battery dimensions, or even better suggest any known reliable replacements for this model. Much obliged!
