Parma OH is up near Cleveland, and it gets very cold there. Almost any battery that is left disconnected and unattended for more than a month or two will self discharge. Once there is no charge in the battery it will freeze and damage the plates. This will probably render the battery unserviceable and you'll need to buy a new one in the spring. You say that it will be unattended with no power from November until April. That's a 6 month period and your battery won't survive freezing weather for that long without having regular maintenance charges to keep it conditioned. I would suggest taking the battery out of the RV, take it home, store it in the garage or basement on wood or rubber if you leave it on the floor. Use a battery charger monthly to top it off or hook it up to a trickle charger (battery maintainer) and check the electrolyte level monthly.

Of course, you could drop it off at WalMart, get a credit and pick up a new battery in the spring. If you leave it in your RV in subzero weather for 6 months, that's what you'll be doing in the spring..... picking up another new battery.
