That's the one I have one 3 batteries. One has to be 10 years old.

I always pull my batteries out of my race cars, offroad trucks, camper, etc. and use cheap Harbor Freight battery tenders on each battery while stored on the garage floor, on a rubber floor mat. So far, they have returned better in the Spring than they did when I pulled them. I've even brought batteries back to life with this method (granted, they weren't completely screwed at that point).
I would suggest pulling the battery and leaving it in the garage with a cheap-A battery tender. Worked well for me.
Careful. The cheap HF tender I bought last week already went tits up...
