    Welcome aboard, greenemachine!

    I can't tell you much about the standups, but I'd recommend that you get a sealed battery. There are lots of brands and places to get them. The best thing to do to extend the life of the battery is to charge it when it's being stored. Plug the charger into a timer and only charge it about 15 minutes per day. I got NINE YEARS out of my original Yuasa battery in my Ultra by doing this.

    welcome to the hulk!

    like steve45 said, charge when its not in use. over the winter i like to put my battery on a trickle charger, keeps it charged but wont overdo it.

    I have a modded 1984 JS440 with 195 psi compression, faster than most 550s.
