Well, I'd love to be able to recommend my company's( Exide) Orbital
Deep-Cycle, but the hacks in Marketing haven't seen fit to give it the green
light yet, and knowing them, it may be quite some time while they argue over
"Demographic Based Colour Scheme Recognition Factors and Point of Sale
Vectors" and the like. So for now, I'd go with the Optima yellow top. Dandy
little batt. If you want to get real tricky, get two Optima 6volt yellow
tops, and wire 'em in nose to tail to get 12v. Gives you a much higher C/20
use time than the 12v. and might just fit the space you've got.
