A new car spec'd for AGM can only use an AGM... Put a lead acid into a vehicle spec'd for AGM and watch it burn out the battery and maybe the alternator.
Yep! Although you can usually re-code the car for lead-acid.

The Walmart MAXX everstart and the Orilly Superstart premium are high rated batteries according to consumer reports. Dont cheap out always buy the premium of the brand . the warranty is longer it it is always heavier the the cheaper counterpart

I’ve had the Maxx batteries last years my my old truck that only gets a 600-700 miles per year, probably less and started once every couple weeks if I happen to remember but often goes a month or more. Really surprised me.

A lot of shops need to up their game then :laughing:
If my cheap Foxwell can do it, a pro-grade scanner definitely can.

I can't argue that, especially since stuff is getting cheaper (or was, no idea how The Coof effected mechanics tools prices this year)

I knew a bunch of old school shops that had pretty ancient scanners, and one mechanic that refused to get one. He specialized in old stuff, and didn't *need* it, but it meant that he only did certain repairs on modern cars. Was the best damn mechanic for real old school cars - carburated stuff - in the Portland area. Then the bastard had to up & die! (He'd appreciate that sort of dark humor)

Before jumping out of battery service and moving to Texas, I was testing out a super cheap Hobo-Freight scan tool that could do resets on certain makes & models. I think I paid $150 for it something, it wasn't their top-tier version of that (yes, I laughed at "top tier" and "hobo freight" being used together too) it was I think more of the mid-range in their scan tool selection. I couldn't re-program a car for lead-acid if it was spec'd AGM, but I could do battery registration at least for the ones we'd run into that required it.

Never buy a cheap battery! Lead acid batteries life is dependent on the PURITY of the lead!

New lead is very pure, and a LOT more expensive than recycled lead. Recycled lead is what is used in short warranty batteries.
While I agree, I had an anomaly. Bought a cheap 6 month warranty recycled battery for my Craftsman riding lawnmower at a local service station when I was in a bind. The battery was 6 years old and still running when I sold it. Mower sat in the garage and I would start it or trickle charge maybe 2 times during the off season of Nov - Feb. I should have load tested it to see where the numbers fell but I never did.

Diehard Platinum/Advanced Auto Parts AGM (Same thing). I run those in all of my vehicles and they have been great. Last one lasted 7 years!

At my shop we sell AC Delco. Personally I despise a sealed battery because I like topping electrolyte and peak charging on occasion. However, we have had most of them make it past the 3 year mark and sadly regardless of brand that's all as long as they last.

I'd go with convenience. Local with a decent warranty.
