I took my first ride of the season today, a 156 miler to Stockbridge, Waterloo, Chelsea and back. It was way overdue, but pressing family needs trump Grandpa's joyrides, and the Michigan spring weather has not been conducive to MC riding either.

My AGM battery has been great since I bought it in spring 2010. I haven't touched it since then: no tender, no trickle, no nothing after a six month park except beaucoup cranking power for the first start of the season
Xtreme AGM permaseal XTA14AHL-BS
2014 EDIT: The battery is now pooped out and wont hold a long term charge. Its on trickle, I'll replace it in the spring or try to nurse it through the season.
