I am going to store the IM off site this year in a climate controlled airplane hanger. I usually trickle charge at home but cant do at the hanger. If I use the battery shutoff does the battery still drain? Or, should I disconnect the battery as well. Thanks.

I don't know how long you intend to leave it but a battery will drain even if left on a shelf. You could disconnect the battery and take it home and leave on trickle charge if you intend to leave for a long time.
It would be best if you could take it home and keep it charged. I love fall but hate winter. Putting the toys up is always sad.
I use disconnects for storage of six months and to date have never had a problem. That doesn't mean I won't...but until I do...I will.
As cold as it gets there - I'd remove battery and take it home for a trickle charge. Remember Bounce dryer sheets to keep mice from making a winter home. And Stabil in gas. I'll give it a winter vacation down here in sunny FL.
For battery questions, get in touch with Dick Trickle. I hear he charges up batteries.
Actually, Marty, I'll be doing the same in a little while. Winter is not kind to our cars, for sure. I store mine in my drive shed, which gives me easy access to it for inspections, etc.
Trouble it, it's too easy to go out there and look at it when the snow is three feet deep...
Hush this talk of three feet of snow right now!
MARTY IF U TAKE THE BATTERY HOME DONT FORGET TO TAKE IT BACK WHEN U PICK UP THE CAR 
Big "G":
I agree with the "take it home" wing. DON'T put it on a concrete floor, but set it on a wooden board. You could even put your trickle charger on it at home - great idea, actually.

What would I do without you? 
Ok, the Battery comes home to trickle.

That would almost be as bad as delivering a car to someone and forgetting the key at home.
Gordon,
I usually take your advice to the bank, but your "concrete floor" advice is at least a decade out of date. Modern batteries are housed in polypropylene and are impervious to the type of surface on they are stored. Plywood, concrete, tile, vinyl, or stone flooring doesn't affect the rate of discharge of modern batteries. The concrete advice was very true when batteries were cased in wood, and somewhat true when hard rubber compounds were used, but those have gone the way of 8-tracks. I had to do lots of battery research before I bought about $20K worth of solar batteries for my business, so I spent lots of time with the wheat and the chaff.
Sometimes we duffers repeat advice we learned as "young uns", which may have been somewhat useful those long years ago, but hasn't been true for a good long while.
Yeah, old habits die hard, and thanks for the update!

And glad I'm still just a "Duffer"........wouldn't want to be thought of as a "Geezer" just yet!
