Here's a weird one for you guys and TLDR: New battery, voltage is 12.5 and radio glitches with headlights OFF and 13.8-14.2 and works OK with headlights ON
2015 Camaro V6 6 speed manual
The car was taking awhile to crank, so a few weeks ago I got my battery tested at AutoZone and they replaced my 3 year old battery under warranty (cool!). It's a Duralast Platinum EFB.
After getting replaced, I now have a problem: When my car is running and headlights are ON, the battery voltage readout on the dash is good - 13.8-14.2 and no issues (for the most part, will get to below)
As soon as I turn my headlights off or it's light out and they auto turn off, the voltage shoots down to 12.5 over a few seconds and the radio glitches out and starts popping through the speakers until I turn the car off, open/close the door and the let the computer kill the power. A few times, the radio has glitched out when the headlights are on at 13.8. I can turn the lights on/off and watch the battery voltage go up-down. When driving with the lights off, the battery will just stay right around 12.5 indefinitely - the battery won't actually die
Is this a bad battery, or did something happen during the battery change that caused some kind of electrical issue? A side note: when bolting on the positive terminal, the socket fell off the ratchet and sparked on the terminal/some kind of metal bracket. Everything else in the car works perfectly except what I described above
