We apologize for the trouble this has caused you. The recommended battery for the Nest Protect is Energizer Ultimate Lithium AA (L91), which is included in the box. Don’t use rechargeable or alkaline batteries. If you do, they will quickly drain and will need to be replaced soon after installing them.

Same problem here. From a search of the threads it looks like this is a common issue, and the threads keep getting locked with the suggestion to use Energizer Lithium (with zero indication that was not being used). I've replaced the Nest Protect batteries (using Energizer Ultimate Lithium) at least 3 times this year so far. I was not expecting $20 upkeep in batteries every 3 months with this. Is there a known problem and solution?
I am having the same exact issue. I have used the proper batteries and one of my Nest Protects is chirping after just a few weeks. This is one I have had since 2016, was fine up until a few months ago when I changed the batteries for the first time after several years, and now this. Google, what is the issue??
I do have the exact same issue with one out of four units purchased in 2019. It got so bad that I now have that unit on a permanent USB power supply, which seems to work.
That whole picky thing about batteries is bollocks; it really doesn't matter if I throw Energizer or Duracells at it, that unit drains them in no time (to test, I put new Duracells in one of the other units, which is still using them trouble free).
The Energizers are relatively hard to get in Europe.
Is there a definite explanation for this phenomenon? Because I find a lot about this issue, but no technical explanation or solution.... 🙄
Same here. The batteries started draining a few months ago (around September of last year like a lot of people in this group). Never had a problem before that and mine was bought a little over two years ago, same as some of the responses here. Sounds like an update issue that is causing the batteries to drain. I'm also suspecting that the batteries are fine because I put new ones in yesterday that are showing up in the app as low today.
I have the same problem - was great for many years on the same set of batteries, now i have to change all the batteries EVERY month. it's so terrible (and expensive) that I have to stop using the smoke detector and look for another solution. maybe Google/Nest wants us to buy the wired model and not use the battery version.
i have the same problem. mfg 12/2018. i have to replace every 3 weeks otherwise, it goes beeps during my sleep and i woke up open the door and i thoguht it was the door bell, i suddently realized it was the **bleep** NEST smoke detector. it was not like this in 2019 and 2020 and 2021 i had to replace every 3 months and now every 3 weeks, i am sick and tired of it....i am planning to use an Amazon styrophone attached to the ceiling and get a usb line 10 feet rolling down and connect to the plug or just buy another smk detctor for $19.95 from H Depot.
I have the same problem with a unit purchased in October 2021. Purchased two, 1 works fine, 1 drained two sets of batteries in two weeks. I'm shocked at the lack of response from Google on this thread/issue. Very damaging to the Nest brand. I planned on purchasing three Nest combo outdoor, wired sensor lights with cameras but will switch to a different brand based on this product and customer service experience .
I’m too experiencing the same issue..
1 of my protects is just eating these Energizer battery’s. (Every couple weeks its drained again…) My other nest works perfectly.
I bought both of them in 2017.
Google/Nest should step up and help us out… this is really annoying that we are all here with the exact same problem..
You must not have a "C" wire or Nest Power Connector installed with your 3rd gen learning thermostat. Every time your nest thermostat runs your hvac it uses the battery and recharges when the hvac system is off. Those discharge/charge cycles degrade the battery just like in you cell phone and over time it adds up and the battery won't hold as much of a charge......when you have a "C" wire the nest never needs to power itself from battery so it never discharhes.
One of three Nest Protects reports (chirps) that batteries are low even when they are fresh. Going with Energizer Ultimate Lithium makes no difference. Google, this problem was reported years ago... and is still not fixed. Why? I will be calling tomorrow to return my Protects and go with a more reliable system. These units are WAY too expensive to be having this problem, and it's just a matter of time before a Class Action forms. Please wake up!
I have 8 nest battery units in my house. 4 of them go through this same exact issue.
Every month, got to replace 24 batteries? 65 bucks. for 24 of these Lithium batteries.
Send me the sign up on the Class Action.. Spent way to much $$ on these Smoke detectors and now, im looking to get all smoke detectors replaced by another Brand\type...
I have 8 as well and none of mine need batteries replaced every month.
Mine get replaced about every 4 months it seems but I do keep the path light on and set to high and it gets activated alot because there is lots of activity at night.
That is a bit expensive for batteries.....I buy these ones they are 24 for $36 currently Voniko AA Batteries, 24 Pack 1.5V Lithium AA Batteries—High Performance Double A Long Lasting Battery for Camera, Flashlight, Toys, Remote Control, Alarm System (Non-Rechargeable) https://a.co/d/3l4jIhh
