I'm storing mine in a friend's lake house garage next weekend and am going to skip the battery tender this year and just try unhooking the negative battery cable.

Will also run the A/C prior to storage; wash/wax exterior; treat conv top, leather & all rubber trim; park it on a plastic sheet with tranny in neutral/chock wheels with handbrake off; car cover on; tennis ***** in exhaust tips & dcon at each end (mice); overinflate tires; add Stabil & top off tank; prop windshield wiper arms away from windshield (per Owner's Manual).

Other than skipping the battery tender, been doing this routine for 9 years without a Spring start-up problem yet. Will drag it back out into the light of day April 1st.

P.S. Snow flurries in Michigan today .......BUT pushing 70 next week
