Why don't you get a battery charger (the kind that monitors the voltage and recharges only when it drops below a certain point)? Come spring, it starts right up. (Don't forget to unplug first.)
I've done this with my NSX for the past eleven winters. I have the 1.5 Amp Fully Automatic Onboard Maintainer/Charger, Item Number SE-1-12S, manufactured by Schumacher Electric Corporation. You can order it direct from their website for $32.99.
Superoir acura here in Kansas told me this is the reason they didn't want to remove battery to check for evap. leak via removing blower motor.they said I might as well remove dash to replace evap. and at that time they could get serial # off back of radio to call acura for code?
now I feel betrayed!
