[QUOTE="FastJoyRide, post: 797989, member: 289"] Not trying to go all NEPRT on y'all, but I think leaving a tender on the FJR battery all Winter will shorten its life (it did mine). These glassmat batteries do not respond to a constant trickle (even from the SMART chargers) the same as the old lead/acid ones did. That's what my local battery expert told me (after the fact - natch!) About 24 hours of charging per month of Winter storage will be tons to keep your battery in peak shape and will deal with the small parasitic drain mentioned above, and won't hurt your battery. I've been doing it that way for the last 3 Winters (since I fried my first FJR's battery very prematurely). YMMV ;) [/QUOTE]
