Yup, battery tender and fuel stabilizer such as Stabile, Seafood, etc., and let it be. Not starting it up will avoid moisture build-up and associated problems. Make sure you DO NOT put a trickle charger on the battery. It will burn up your battery. Buying a smart-charger or Battery Tender is money very well-spent, as it senses when your battery is charged and shuts off, but monitors the battery's charge level. When it senses that it is below a predetermined level, it comes on again just enough to bring it back up to spec. A trickle charger will just stay on until the battery is overcharged/overheats, and then dies.
