90 days is perfectly safe except perhaps in the desert.
Yes, I've been to Maine and it isn't the desert. It stays much cooler through the summer months and much colder in the winter months - all excellent temps for protecting lead acid batteries, as I stated in my last post. Just one example of the average temps at Ogunquit: Average Weather for Ogunquit, ME - Temperature and Precipitation
If the battery in that link is supposed to still be used, it never should have been tested down to 10.5 volts (0% SOC), which has done permanent damage.
You must recharge overnight every 30 days, unless it is mid-winter... or you live in Maine.
