Is my battery over charging? - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

It's about 40 degrees out here and I was driving my camaro ss. I let it warm up a little and I noticed for the first time I noticed the battery gauge was right in between the 12 and 19 volts. It has never been like this and nothing has really changed. I drove it for about 30 min and it didn't change. Is this normal or is something wrong? Everything electronically works fine and there's no check engine light. Thank you in advance!

your fine man, batteries fluctuate with heat and cold. and actually heat is the enemy of your battery over cold

You can check the battery voltage on the display screen too, which will tell you exactly where it's at since some of those gauges are not always evenly spaced, coolant and battery voltage almost never is.

My stock 2013 LS radio is going crazy. It runs between 15.1 and 15.2 volts. I ran the car for over an hour and this voltage was constant. I soon as I got home I checked the battery. It read 12.63 volts. I started it and it read 14.9 volts, but after 60 seconds or so, it went to 15.1, 15.2 again. The radio works fine in accessory mode. Also works fine with the engine running but the alternator disconnected. The dealer swapped out the alternator but that didn’t fix it. Is it overcharging and could the new alternator (voltage regulator) be bad?
