As I stated before, I've used this medium strand count cable before and found it to be the optimum combination of flexibility vs. working in regular connections without any special adapters.<div>I too have always wondered about the MTW cable listing of some other cables.</div><div>The problem I see now with the Copflex, though, is that it doesn't have a specific mention of Acid resistance, but since none of the cables listed in NEC table 310.13 mention acid resistance, I'm muddling forward. Forget what I said before about this being the "perfect" battery cable. Its still the best choice of what's available IMHO.</div><div>Once you strip and make a connection with this medium strand count cable, you won't want to go back to connections with the little fairy hairs of copper in the X-flex.</div><div><br><div> <br><div>
