does anybody know where i can get a battery for a s1 turbo,tried local motorfactors,halfords etc,they all seem to be round terminal type,im after the square type,any sites reccomended,dont really want to change the leads to round,as the car is standard and all original,its been 4yrs since last battery change,it was difficult back then to get one,so any help would be greatly appreciated.......cheers
