The "battery fully charged" alert is one of the more annoying features I've come across. If I walk away from my computer after locking the screen or even put it to sleep, the stupid thing chirps away every 30 seconds telling me that it's fully charged. It annoys me and the people around me.
How do I make it stop?
MacBook Pro 13″, macOS 11.6
OK, problem solved thanks to Apple Support. They were very stumped by this one, but the senior support engineer had the idea that maybe it was a hardware issue with the charger. I swapped out the block and cable with a new one, and poof! No more problem.
FWIW, the faulty charger was also preventing me from being able to shut down the device completely. I would select Shut Down... from the Apple menu but could only get the device to go to sleep, not shut down. It woke back up with any keystroke or trackpad click. The same was true when trying to shut down using a hard reboot by holding the power key down.

This sounds like third party software you have installed.
To trouble shoot further you can:
—Try a SafeBoot https://support.apple.com/en-us/HT201262
Takes noticeable longer to get to the login screen, does a 5 minute disk repair before it fully boots up, and certain system caches get cleared and rebuilt, including dynamic loader cache, etc.
Login and test. Reboot as normal and test. Caches get rebuilt automatically.
In Safe mode third party system modifications and system accelerations are disabled, it removes malware, etc hampering smooth operation, however a reboot will put it back to normal mode.
This test will tell you if third party interference; extensions etc are not loaded in safe boot mode.
There are some ideas here, that may include 'how to stifle an annoying notification' that one certainly is.

Ask someone who's very savvy and knows command-line or terminal well.
Mine, are older and don't voice their opinions very often.
I didn't know the MacOS could/would do that. It never has on my computers. I believe there are third party apps that might do that. Have you installed such a thing?
I've never heard such an alert. But, I always close my computer when I walk away from it. Especially if there are other people around.
To my knowledge, no, but maybe my company installed something that I don't know about. This is the sixth MacBook I've had and the first to have this annoyance.
The alert happens even if the laptop is closed. If it's plugged in and fully charged, it chirps unless I'm actively using it.
One way to see what is installed at various levels is to run EtreCheck. You could post the result here and someone might spot the culprit.
