Hi im buying a new battery for my rs turbo and was wondering if anyone can tell me what model battery should be on the car? not bothered about the make, but think the difference is cranking power one is 300amps and the other 600amp will it make much difference if i get the 300amp one?

Is it an 085 or an 097?

Thanks

 

hope its 085 as thats what i was sold

 

I just got the biggest that would fit, mine is around 640amps.
