Great move on going with an AGM! That's the only way to go on these newer trucks.
Believe it or not, the OEM battery was also an AGM, I was surprised. But yea, I put another AGM in as well.
I have a 2023 xl Denali.
Due ro stuff i have every so often when GM tries to send updates my truck goes dead. The first sign is the foot boards don't deploy. Just keep an 8mil socket in the truck undo the negative and wait 30 seconds. This erases any code in the computer. as i said not the trucks fault it the anti theft stuff i have. I can kill the truck anywhere when it stops moving for 10 seconds. It's worth the trouble. IMO
Strange you shouldn't have to do that. Maybe check your battery, i know yours is a 2023, but who knows maybe its bad. Also 10mm is the neg battery cable for clarification. I've put a nut driver in the glove box...just in case.
up my '21 YUKON SLT XL was giving me a 'no key' message, same thing happened to my Daughter in her Lincoln. I replace battery with Walmart's best battery and all that BS stopped. Great advice from the pro's here on TYF.com & everyday users. Thx. I put 'check Yuke' battery on annual reminder in my phone.
Right on! Good idea to check the battery on a yearly schedule, can't hurt I guess.
On a side note, IDK how much stock this holds, but I purchased a couple of Faraday pouches for the key fobs to be stored in when they aren't being used in the truck. I ready somewhere that if the key fobs are within a certain distance of the truck, it will continually "check in" with them, and that could cause some parasitic drain. We store the fob within about 10' of the truck, just inside the door to the garage. Again, dunno how true that actually is, but the Faraday pouches were cheap, and it blocks the key fob from communicating with the truck when it's parked and not in use in the garage.
These are the ones I bought.
