I decided to go to Autozone and get my battery testest, so did the first cold start, drove 2 miles and had them test the battery with the car shut off.

Their tester shows "good battery" but with only 50% Charge at 12.24V. This was done directly on the battery posts.

I'm not experiencing any common issues with a bad battery but chasing others and just trying everything I can.

Should I replace it with an AGM? Battery is only little over a year old, Exide Extreme L5/49.
