QSilver7 as always has the info at his finger tips.

In your area the temps drop to ZERO frequently in the winter. That temp is what drives batteries to die. In AZ the opposite end of the temp scale happens, 100 degrees is normal in the summer. In these two examples you should always get the biggest, baddest, highest COLD Cranking amps (when measured at ZERO degrees). Buy the 95R (H9).

Now you get the wrestle that 64# into the spare tire well and the old one out. You will enjoy that experience. Don't for get to vacuum when you in there and check all the electrical connections as all the expensive electronics are in there along with the air suspension pump.

Now go out and save up for that garage home where the heat of your vehicle will warm up the space all night and you will be toasty in the morning, instead of freezing your butt off.
