Another $50 Battery option

[Dezeez]

I needed a new battery and decided I wanted an AGM type. I take pretty good care of my batteries and usually get several years out of the lead acids. I thought about the Odessey but it would have to last for at least six years to pay for itself so I started checking around and found this alternative. Very similiar to the P680 specs and I got mine for $56 shipped. I've been using it for a couple of weeks now and it works great. The terminals are different from stock and only required that I twist the cables 90 degrees to get them on. It's also slightly wider and a little shorter but fits in the Max box without any modifications.
