Battery matching has become a game like any other IMHO. Although I admit I don't know everything about matching... differences in cutoff, etc affect the numbers you get. My best advise to people when they ask me is to find a reputable company and stay with them. This is more for the sake of true comparison. Regardless of the #'s, if you have a new pack matched by the same people on the same machines and it has higher #'s, its obviously better than the one you already have. There are plenty of very well established companies (both down here in the states and in the great white north...hey Danny) and I feel that consistancy answers this question better than anything. If you find a new company that sounds good however... what does it hurt to try them. Maybe you'll find someone your happier with. I've found two things when it comes to batteries. The company I've been using has continually kept me happy, and that batteries won't buy you laps.
