Troubleshoot when Nest Protect batteries are low out of the box

If Google Nest Protect chirps or notifies you in the app that the batteries are low after initial setup it's possible that the batteries’ voltage has temporarily dropped. This can sometimes happen when it takes longer than expected to connect your new Nest Protect to your Wi-Fi network and add it to your account. There are a couple of solutions depending on what you see and hear.

If you get a low-battery message in the app but Nest Protect doesn't chirp

If you get a message in the Nest app right after you've added your Nest Protect to your account, but you don't hear a chirp, you can just mount it and wait a day or two and see if the issue resolves itself.

If you hear a low-battery chirp from Nest Protect

If your Nest Protect chirps right after you've added it to your
account in the app, follow these steps to get the batteries back up
to a full charge:

  1. Take the batteries out for about four hours

  1. Once you put them back in, connect your Nest Protect to Wi-Fi
    by pressing the Nest button.
  2. Check Battery in the Nest app. It should have a green
    checkmark next to it, indicating that the battery charge is back
    to normal.

Note: If you don't see a blue light or hear the welcome message after removing the Nest Protect battery tab, it may seem like the batteries are dead. However, it's more likely they have come loose in shipping and only need to be pushed back in. Check out the article below to learn more about fixing this issue.
