The product, in the report: Google Nest Protect smoke detector

One of my Nest Protects chirped, and the app said I had a low battery. When I removed the batteries, one of them was very HOT to the touch.
UPDATED ON 1/8/2025: [Description of Risk of Harm: the battery became so hot it burned my fingers. Someone changing the batteries while on a ladder could lose their balance and fall off because of the burning. Left in place, I wonder if the battery could have continued to overhead and start a fire.]

The product, in the report: Google Nest Protect Smoke Detector

Google Nest protect smoke detector gave a warning that battery was low and to replace them. When I went to replace the battery one of them was extremely hot. Ive now read online that this has happened to others as well. These seems like it was an overheating lithium battery and seems like a potential fire hazard.

The product, in the report: Google battery operated photoelectric smoke alarm

Google Nest Protect - Smoke Alarm and Carbon Monoxide Detector - Battery Operated Model Topaz-2.9 started to chirp early in the morning. Got an alert the batteries were low. Took the smoke detector down and went to take the batteries out. One of the batteries was extremely hot, so hot I couldn’t take it out without burning my fingers. Had to wait for it to cool down. I did an internet search and saw this is a common problem. Called Google and they wanted me to replace the batteries and see if it happened again. I said that seems unsafe and didn’t want to risk that happening again. I am waiting for a return phone call from them.

The product, in the report: Google Nest Protect - Battery operated

I have 8 Nest Protect generation 2 in the house. One of these just started chirping and indicating very low battery. I went to replace the batteries with new [REDACTED] lithium cells (manufacturer recommended) and found that one of the old batteries was very hot. I measured the exterior temperature at 135 degrees F. What is causing this? I don’t want my smoke detectors to cause a fire.

Nest is committed to designing safe, high quality, and effective products that help people in their homes. When customers have an issue with one of our products, we ask that they contact Nest to provide us with information and the opportunity to retrieve and examine the product. This provides us information that helps us continually monitor the efficacy of our products and identify opportunities for quality improvement or required corrective action. The user describes that the batteries were hot to the touch. The customer also expressed a concern that the batteries might be hot enough to ignite materials. However, there are safety features built into our product and the recommended batteries that are designed to eliminate any such potential hazard, for example the type of materials used and electrical fail-safe features that respond to high temperature. As the customer described, the smoke alarm alerted the user of a problem with the supply of electrical power from the batteries, which is consistent with the product’s design. We are trying to contact the customer to help resolve their issue.

The product, in the report: Google Nest Protect models Topaz-2.7 and Topaz 2.9. Software version 3.4rc6 Smoke alarm

Google Nest Protect smoke detectors are not sounding the alarm at every smoke detector when smoke is detected. Google’s specifications, as well as fire/building codes in California and other states, require smoke detectors to sound an alarm at every detector when any detector senses smoke.
This is a serious safety hazard. This functionality is required to ensure that everyone in a house is alerted when a fire is detected somewhere in the building.
Details: My home has 7 Nest Protect smoke detectors. I have tested the system using a blown out match as well as canned smoke at multiple different detectors. In each case, the individual Protect detected the smoke and sounded its alarm (an actual “emergency” alarm--not a “heads up”). In addition, I receive an “Emergency: There is smoke” notification on my phone. However, the alarm did not sound on any of the other 6 Nest Protects. Nest’s built-in test shows that all 7 Protects are correctly interconnected and operating properly.
I have reported this issue to Google’s support on 3 separate occasions with no response: 1) On 10/27/2021, I reported this to Google’s chat support. After escalation, Google told me they do not recommend testing the Nest Protect this way and disconnected. 2) On 10/27/2021, I reported this to Google’s phone support. The support rep agreed this was an issue, escalated the incident to the Nest safety team and told me I should hear back within 24 hours. I have not yet had a response. 3) On October 31, I posted this incident on Google’s Nest Community. The Product Expert there agreed this was an issue and escalated it to the Google team. I have not yet had a response.
