Just bought a Costco Interstate Group 48 H6 battery yesterday for my 2015 Equinox. Looks identical to the battery in post #36, with the exception that it has a 12/24 date sticker on it. $129.99. 36 month prorated warranty (which doesn't bother me at all.) Walmart Everstart Maxx was going to be $149. Costco was more convenient, and I have heard that Walmart these days is an absolute nightmare to deal with for the core exchange. Costco was quick and easy and returning the core a couple of hours later was no hassle.
The new battery replaces an Autocraft Silver from AAP from 12/19 (that was less than $100 back then.) The battery casing on the outgoing Autocraft was literally identical to the new Interstate battery. Most likely made by the same manufacturer (assuming JC/Clarios). The Autocraft had a 3yr warranty and lasted 5 years. It was still starting the car, but was only holding 12V overnight then dropping to 11V when unlocking the car with the fob, and dropping to 9.0V while cranking (and cranking was getting noticeably slower.) 5 years is my personal limit with a car battery, especially with winter getting ready to set in. Could the old Autocraft battery have made it through the winter? Possibly, but better safe than sorry. Replacing a battery on a 2nd gen Equinox is an absolute pain and better done when the weather is still somewhat decent.
