Costco, currently in both our vehicles and I've used then in 4 others over the years without a failure. The price is tough to beat and 3yr replacement warranty is solid.
Costco was my top pick, but they don't carry them in my area for some reason.

Well, Weider has been making fitness products since 1936, been sued (and lost) for false advertising on a grand scale numerous times and has been making absolute garbage equipment since at least the 80s - but they're still here 86 years later. A longstanding business is the result of management and marketing, not an indication of a quality product. As for the batteries, it seems like a crapshoot these days. I'm satisfied to get 3 years and if I get more, great.

Suppose in many cases the same can be said of Ford, Chrysler, GM, just about any company these days. Even the awesome ones out there (like Optima back in the days), sell out and become crap, but the many of the reviews from East Penn were decent or better, given the price delta between say that and a Bosch, which I couldn't get in my state, it was worth it.

Make sure it is an AGM battery (Absorbed Glass Matt)
Regular lead acid batteries won't last very long

My local Costco now carries the Interstate Group 94R H7 AGM for $184.99. When I checked last November they did not carry it.

My Motorcraft batteries have all failed prematurely, so I gave up on them years ago. I was buying Autocraft Gold (Advance Auto house brand, made by Johnson Controls), but neither the house brand nor JC is still in existence. Clarios has taken over the JC operation though, so I suppose I'll give them a shot next time around.

Just a couple of comments - I use the largest group size that will fit in the battery tray and I have many CTEK battery tenders on all my vehicles. The AGM charging profile is different than a normal flooded acid battery - get the charging profile from the manufacturer and charge accordingly. The CTEK does have an AGM charging profile. I have AGM's lasting 10 years................

Lead acid and AGM batteries have different service voltage requirements. When I switched to an AGM from a lead acid battery on my Toyota Tundra, I had to add a voltage booster (resister) to trick the alternator into outputting ~14.6 volts. Are the AGM folks doing anything to their Expys to accommodate the voltage the voltage discrepancy?

The owners manual for my 2019 specifies the model for the battery as BAGM-94RH7-800 which is already an AGM battery.
