Your post says you have a 2nd gen Google Nest Doorbell, but your subscription seems to be referring to the problem in 1st gen Google Nest Hello Doorbells where, if the internal battery fails, the doorbell goes offline for a minute whenever the doorbell button is pressed. That issue is tracked in this now-locked thread with over 1,000 replies:

That has happened to all 3 of our Nest Hello Doorbells. The simplest workaround is to turn off the "Indoor chime" option (in which case the doorbell and its camera no longer go offline when the doorbell button is pressed), and rely instead on "Visitor announcements" (https://support.google.com/googlenest/answer/7672451) on your Nest Hubs and Nest Minis and Nest speakers. That's what we've done for about a year.
For many (most?) customers, Google Nest has said it "cannot" replace Nest Hellos with this defect if they are past the 1-year warranty.
Some customers have endeavored to pry open their doorbell and replace the battery:

If this is happening with your 2nd gen Google Nest Doorbell, it would be the first case I've seen reported in this forum.
Is your issue something else?
