Why did I suddenly start getting battery needs service messages on my 2017 Macbook Pro after installing Monterey?

sounds like a service recommended message...there is just two conditions (Normal and Service Recommended).

If the battery is working well enough to meet your needs you can ignore it, otherwise take it in for replacement.

Seems Apple fine tuned their battery management system.

But, depending on the use of your MacBook Pro, it could really be time to replace the battery.

I did get this message in Mojave after 8 years of use, but my MacBook Pro has been connected to the charger most of the time.

Getting it replaced by visiting an Authorized Apple Service Provider was an easy process.
