2023 GV70 2.5T Prestige
Update:
A little late as I have been busy.
Let me begin by saying.....I'm an idiot.
So, after installing the Energizer, I decided to put it on the NOCO to slow charge to max. Then I noticed that the NOCO was set to standard 12v, not AGM. So changed it but it got me thinking, when and how did it change. I had unplugged it but it should retain last setting. That's when the lightbulb went off. What if I had been trickle charging my OEM in stnd rather than AGM mode. Hooked it up and let it charge on AGM. Once charged, checked the voltage ...12.6v. Damn, that's voltage of a good AGM battery. So, for sh!ts and giggles, I decided to get it tested under load. Well guess what? Test came back...perfectly good battery. So, it seems that my OEM was never getting fully charged under stnd mode and with my limited driving and often shorter distances, battery could never get fully charged..
Long and Short...put OEM back in and it has been perfect. Energizer (never left the garage while in the car) went back to Costco today.
Moral of the story...don't do dumb sh!t like I did LoL.
