I have parked my truck for the winter for 40+ years, it can sit there for 5+ months never going anywhere, never starting it, then in the spring I walk up to it and turn the key and wroom off it goes, usually starts like it did the day I left it... Now sometimes I do have to crank it 2X before it actually keeps running, but that's it... 5 +months of as cold as -20 to -35*C and no problem...
EDIT; And oh yea,they are about $200 for a real good one (battery)... WTF with this $900 or so for a BionX battery?
I think you should log your story with Guinniss World Records -seriously! They may laugh at you but its worth a shot!
If you are going to have a battery in storage for months at a time in a car, disconnect it from the car, it will reduce the discharge. Or, periodically charge the battery, maybe once every 2 to 4 weeks. If you have it in storage disconnected from the car, a charge every month or two will help keep the self discharge from draining the battery. You may also look for regulated trickle chargers that are designed for this type of application. Thanks to a former auto company engineer for this tip.
