Were the doors locked or unlocked during its slumber. On my original factory battery, I stored it every winter w/o starting it or having it on a trickle charger for the first 5-6 years and it started like a champ in the spring. Some others had similar experiences whereas others did not. The only possible common thread might have been the former folks leaving the doors locked vs the latter not.
That said, I do keep it on a trickle charger now. I have only had an issue starting the car if my phone was plugged in the charger prior to starting the car...which is still weird to me.
