IMHO I think what warms up the batteries is a good amps pull on 'em, either headlights for a few minutes, or a quick start attempt for a few seconds.

Mark, mine hasn't been on the charger since install and I've been running a Gerbing heated jacket liner on full on the rides, no mercy. Still fires the bike right off. Above freezing it's usually first cranks and it goes, doesn't need the internal warmup. Good thing too, because with no kicker, and standard auto-clutch, there's no push starting it either. Your GG must be a tough one to get going.
these are notorious for killing even the best battery.. I still have a kick starter though, yeah, id say your battery better start, :)
