I have a 2022 Sahara 4xe with 44k miles. Original 12v battery. It's been problem free but today after parking it for about 2 hours, it would not start. When starting, the dash lit up with a check engine light, the charging cord symbol in red, and service charging system flashed. I assumed it was a bad 12v battery. I jump started it and it started fine. Drove it straight to the auto parts store and had the 12v battery tested along with the charging system. Everything tested out fine, and it's been problem free the last 3 times I went to drive it. Is it likely a bad 12v battery and I should change it out even though it tested out fine? Or is this hinting at something bigger with the hybrid system or something?

Your run-of-the-mill auto parts stores like Autozone, Advance Auto, O'Reilly's, etc. will only test the battery for surface voltage. They won't test for the actual state of health (SoH) or even perform a proper load test.

I should have noted when I got home I ran it through Jscan and everything appeared normal. It had a bunch of low voltage codes but I cleared them and they haven't come back.
