Hi again,
i’m going to replace the car battery and see how things go for the next few days since the voltage is too low to start. If it’s still draining then I’ll bring it in for service to my Chevrolet dealer.I’ve watched a few videos and looked that information on how to replace the car battery ( I’ve replaced many a car battery over the years).Is it simple enough to basically replace the car battery which seems simple and straightforward for me or do I need to reset some computer software, which I have no way to do that unless it’s without a Diagnostic Scan Tool?
thanks

According to the service manual, the battery monitor in the car needs to be re-calibrated. To do that, after you install the battery (and it does not have to be right away) you let the car sit for at least 4 hours off and undisturbed. This will happen while it sits overnight, so no action is really needed for it. Just put it in and drive if you want. When you are done for the day and shut it off it will calibrate overnight.
The battery is covered under the three year B2B warranty if that is still in effect.

No special tools needed. You won't lose our memory settings. You will or may need to re-index your windows, no tool required for that.

I have a '23 too in Long Island with the original battery. I kept the tender on it during the blizzard for about 2 weeks. Since then, when driving, I notice sometimes the DIC reads 12.5 volts, other times it will jump to 14.5. I know the voltage reading can vary quite a bit and its not a good sign of a good or bad battery but I think im on borrowed time and I may need to just replace it.

What you are reading on DIC voltage display is charging voltage. Most of the time, when the battery as reached 80% state of charge (SOC) it will go into fuel economy mode - and the voltage will be 12.5-13.1 volts. However, in "Headlamp" mode it will be between 13.9-14.5V. Just after start up it will be 14.5V. It has a Battery Sulfation Mode periodically and this causes it to enter "Charge Mode" for 3 minutes, during which it can be between 13.9V and 15.5V. It will also enter the Charge Mode if the wipers are on, or if HVAC fan is on high. Like you said, the normal range is 12.5 to 15.5 volts and depends on a variety of factors. Bottom line is that you could easily see 12.5V and jumps to 14.5V and the system is perfectly normal.
I personally think the voltage reading is one of the most useless of the available info tiles, and I never display it.
