Just remember the ol timers battery formula:
States other than N. Dakota, Alaska & others that get frigid regularly: 250cca + 1cca for every cubic inch of engine displacement.
Frigid states, start at 500cca, then add in 1cca for cubic inch of engine displacement.
I guarantee it'll be larger than stock, but try to find one that'll fit in the tray. You'll only need a jump if the alternator goes out and you leave the lights on overnight accidentally.
Now for wx: getting freezing rain. Heavy at times. Calling for snow later that'll make the roads even mote fun. Stay safe out there ya'll.
