I went 7 years on my 350z with the same original battery that came with the car when I lived up north storing it for 5 months during each winter
I had a religeous schedule for prepping for storage. It worked for me
1. Change oil
2. Fill tire pressure to 38 psi in all
3. Put in gas stabilizer (amsoil) with a full tank of gas
4. Wash car/wheels and dry to ensure no bugs or dirt is left on the car
5. Start the car once a week and let it run for 15 min each time
6. Roll car forward or backwards a couple inches each week to prevent flat spots in tires

For 7 seasons I didn't have one problem with battery, performance loss or any other significant issues that you can run into while storing.

Now that I'm down south I only put my car up for the 1 cold month we have and still run an amsoil gas stabilizer and start up once a week while rolling the car either forward or backwards to prevent flat spots in the tires.

I hope this helps gentlemen.
