Swapped out the stock AGM lump for a Battery Tender LiFE unit. Dropped 6 pounds like a bad habit, and she's back to starting quickly again. Granted, that would happen just swapping in any new battery in place of a dead one, but given the size and weight of the new unit, I'm pleasantly surprised. No issues running the heated grips and seat, although I've taken to cutting both of those off when I'm 3-5 minutes from my destination, just so I'm not draining the battery unnecessarily right before shutting the bike off. Might help, might not, but it makes sense in my head, so I'll keep doing it.
Using the included foam wedges to make the new unit fit in the space for the old one was less than optimal. I don't understand why they don't just make a 'racing' version that is reduced size so you can eliminate the battery tray on a race bike, and a 'road' version that weighs maybe an ounce more, but comes in a plastic shell that is the same size as an original battery. Battery hold-down setups are built by the manufacturers for a given size, and swapping in an equally sized, but radically lighter unit would be easier for the consumer. Just sayin'...
