Dave, I used to do that w/ my C3. I treated it like my boat, fogged the cylinders, sta-bil in a full tank of gas, and remove the battery & stored it a wood box...unless you use a charger that is not a trickle charger type....those will boil off all the electrolite....I believe the correct type of charger is called a "float" type, it reads the state of battery charge and only charges the battery when it goes below a certain voltage, brings it back up to spec and then shuts off.
