wow - old thread!

FYI, I've become an Optima convert after I got acid all over EVERYTHING from that Wal Mart battery. It's damn near impossible to get that crap all cleaned up and neutralized.

The Red top is the right one for regular applications (yellow top is a deeper cycle battery - not quiiite as good for starting - but better for long term high drain devices like a lot of offroad lights, a competition stereo, or a winch). You can get 'em at Sam's Club for about $100.
