I was going to explain in detail but i am afraid he just doesnt understand well enough.go do some reading then anything you dont understand you can ask me directly via pm and i will explain it thoroughly.
but dont waste money on an overpriced pos optima battery, for 120 shipped you can buy an hc600 that has more power than any optima does and optimas run upto 220 each depending where you buy.
i know I will prolly get flamed for calling Optimas a pos but trust me on it, i live right close to where they are made in aurora colorado and i know tons of people that work there and they would never buy 1 for many reasons.
