I live in New England so the salt is heavy and do not want to drive it until March. I do not have access to using a battery tender so what’s the next best thing? Can I leave the terminal off? Or do these cars needs constant power.

I can’t get a battery tender. No outlets.
Will be your car be stored in a garage or somewhere Inside? If so, I'm sure an outlet with an extension cord helps.

Just disconnect the battery if you are that worried about it. If super worried about it, take it out and set it on a tender in your home. BUT this is my car when the vehicle goes in its sleep mode, after 30 mins being left alone.

.009 was sometimes going to .010

And from what i can gather a 105ah battery will last.... 1year 4 months ....

Your draw on the battery is very very little. I wouldn't worry about 3-4 months myself if i had no way to get a tender on it. At most id disconnect the neg lead and leave it at that myself.

Edit: had the mA selected giving the 1100+ years of battery life, i thought that seemed off. Needed to correct myself.

I’ve got a car outside covered but have a 30ft extension on the tender hooked up and works great.

Store your vehicle somewhere other than a damn Amish paradise
I saw an Amish kid using an iPhone... isn't that illegal? Was about to call ICE.
