We're sorry to hear about your low battery issues! That's definitely concerning to have your device drained. Let's see what's going on here.
Due to the nature of your issue, I will be reaching out to you privately. Be on the lookout for an email from Google Nest Support with your specific case number in the subject line. Thank you so much for your patience!

Interesting, I just had exactly the same thing happen with mine. It's from 2015 and I think it has lasted this long on the original set of batteries: they're marked "Not for retail trade" and have an expiration date of 2035, which given the 20 year shelf life suggests they were from 2015.
I finally got a low battery warning, so I put in a set of new Energizer Ultimate Lithium AAs. When I took the old ones out, it chirped once, and when I put the new ones it is now completely dead. It's not the batteries; I tried changing them again. I also tested the new batteries and they are all ~1.8 volts.
I have 10 of these Nest Protects and I hope they don't all have a failure mode where they die after changing the batteries. They're supposed to last 10 years but only have a 2 year warranty, so that's over a thousand dollars if they all fail.
I'm back a minute later to report that I seem to have solved my own problem. I was thinking about my limited experience with electronics as a hobby and I thought "maybe there's a capacitor or something that needs to discharge completely in order to reset properly", so I left the batteries out for about 5 minutes while I was writing the above post. I just put them back in and it came back to life.
So if anyone else sees this and has the same issue - try giving it a little break between removing the old batteries and putting the new ones in and see if that helps.

Glad that everything has been sorted out here. It looks like we can consider this one complete. I'll be locking this thread if we won't hear back from you again in 24 hours. Should that happen, feel free to create a new one if you have more questions or have other concerns in the future.
