What would be a replacement battery better than oem in cranking power and longevity?
The AT-equipped '07 was fitted with a size 75D23L battery ("12V, 52Ah"), and the MT version was fitted with a size 55D23L ("12V, 48Ah"). See OM page 12-3. You may want to look for the larger battery (assuming the mounting hardware is compatible).
Our original '07 cranks slower than I like on a cold start and winter is coming.
Considering your location, you may want to look into "North
" versions of candidate batteries (i.e., various DieHards, or Everstart MAXX-35N). Batteries available in "temperate" locations are labeled "South" (i.e., various DieHards, or Everstart MAXX-35S), and batteries intended for use in both regions don't carry such labels (i.e., Interstate).
I am wary of the Walmart, Autozone and Advance Autoparts products since I had a terminal break off a brand new battery for another vehicle from Autozone a few years ago.
Many car batteries are manufactured by Johnson Controls; check the label(s) on the battery. We live in a mixed-bag climate (avg Jan low = 25F, avg July hi = 89F; don't ask about the records!), and our 00 pickup and our 06 Accord are presently both fitted with Interstate batteries. I've had good luck with this brand, and their local dealer is close by.
has published results and ratings from their extensive testing of car batteries.
