COSTCO sells “standard”and AGM lead acid batteries and offers them as performance upgrades with “superior technology.” I just checked their catalog and they still offer both types for my vehicle. I purchased one for my Honda Ridgeline a couple of years ago knowing the charging profiles were different but neither COSTCO or any written source I could find at the time said this would be would not be a good thing to do. The only guidance I could find was to periodically connect a battery maintainer. I then checked and found that the Battery Tender battery maintainer I have does not seem to care what kind of battery you connect it to (there is no battery type setting). I believe they somehow automatically detect and adjust their voltage but I’m really not sure what they do or how they do it. This article did not help in that they did not specifically say it was bad to upgrade to an AGM but they didn’t say it was good either. I couldn’t find any info on whether my vehicle’s charging system was designed to work with either battery type. I’d appreciate hearing any wisdom that anyone has to share. I’ve had the COSTCO AGM battery in my car for several years now and all has been good so far.

ANY of the Victron chargers (Orion, Multiplus, Mppt, or Smart chargers) are infinitely adjustable to whatever profile you want using a very user friendly App.

This gizmo is just a advertisement that is a bit exaggerating.

I have a 2025 Ford Super Duty pickup. They do have adjustments for the battery type in the BCM (Body Control Module). This can be done by the owner if you have Forscan or a two way scanner. You can also have the dealer make the change if that is your only option. You should also do a battery reset when installing new batteries in the Super Duty pickups. I do not know if the other brand of vehicles have this option.
