    My 2010 will have been unused for 2 months. The 12v battery was replaced about a year ago, but I'm still expecting it to be pretty well discharged.

    If it doesn't start, I plan on using my Noco Genius 10 charger, set to AGM mode, to charge the 12v battery overnight (connecting via the fuse box). Is there any reason not to do this? Calling AAA for a jump would be the fall-back plan.

    Thanks....

    no reason at all. just make sure you make contact with the metal side of the jump point.

    the fall back plan could be to crawl in the hatch and use the emergency hatch opener, then put the charger directly on the 12v.
    it is unlikely that it won't charge after 2 months. if it won't you're gonna need a new one anyway, unless you have no way to get to the store.
    consider a jump pack as well.

    Why not just put the battery charger on it now? Charge it every couple weeks to keep it from dying

    If you have the time, it's probably best to simply charge up the battery all to way to max charge before bothering with starting up the car.

    Good suggestions, thanks.
    I live 8hrs away from where the car is stored, and I'm heading there today.
    Good suggestion to just charge overnight, and not bother trying to start it first.

    Just make sure you're using a legitmate charge because those cheap trickle chargers are always failing at charging up any meaningful amount of discharge.
