Brand New Nest Protect chirping

[TRDGUY]

I just installed a brand new wired nest protect. It had been beeping every minute and complaining about low batteries even after replacing them with new L91’s. I also made sure the firmware was updated to the latest. This is so frustrating.

Hello TRDGUY,

Thanks for posting in the Community.

I’m sorry to hear that you’re having trouble with the Nest Protect. I appreciate you sharing all the steps you’ve tried to fix the issue. Let’s check it out.

After Nest Protect is paired or processes a software update, Nest Protect will calibrate its sensors and battery level over the next 24 hours. Leave the original batteries in the Nest Protect for now. If the low battery alert ceases after 24 to 48 hours, it’s expected behavior.

If the issue persists, please follow the steps below:

1. Go to your Nest Protect and press the Nest button on it once. It should say, “Ready. Press to test."
2. Press and hold the button until it chimes and says “Version number...".

To further assist you, please provide the Nest Protect’s software version.

Looking forward to your response,

Lance

I’ve done the factory reset a few times and it still beeps with messages with a low battery warning. With known good batteries. I wound up exchanging it for a new one and it works fine.
