Scalding hot battery in nest protect

[jmd23]

I believe my Google Nest product to be faulty.

I have installed the recommended Energizer Ultimate Lithium batteries in my 2x Google Nest smoke alarms.

I have one alarm upstairs and another downstairs. They both contain fairly new batteries. The downstairs alarm was beeping every 60 seconds - as if the batteries were low - so I went down to check it but the batteries were scalding hot. They burned my finger while removing them - some were hotter than others. This seems really dangerous to me - the level of heat was way beyond normal. This is the second time it's happened - the first time was a few months ago and I replaced the batteries, but now it's happened again I know it can't be the batteries at fault - I think the unit is at fault. I searched the forums and was dismayed to find that this is a surprisingly common occurrence and many other people had experienced the same issue.

I already filled in the form that was available on one of the other forum posts, 
If someone could come back to me as soon as possible I would appreciate it. Many thanks

This is a serious safety issue! Scalding hot batteries in Nest Protect units are unacceptable and clearly indicate a defect in the device, not the batteries. Multiple users have reported identical problems, suggesting a potential manufacturing flaw or design failure. Google should urgently investigate and recall affected units. **Stop using these alarms immediately** and contact Google Support for a replacement or refund. Safety first!"

**Key Points:**
- **Risk**: Overheating batteries can lead to fires or burns, defeating the purpose of a safety device.
- **Pattern**: This is a recurring issue (as seen in forums), not an isolated incident.
- **Action Needed**: Google must acknowledge the flaw and proactively replace faulty units.

**Advice for Users:**
1. Remove the batteries and unplug the Nest Protect (if wired).
2. Report the issue to Google Support directly [here](https://support.google.com/googlenest/contact/alias_emergency).
3. Replace with a temporary smoke alarm until resolved.

Hope Google addresses this swiftly! 🚨🔥

Thanks for your message SeoBlogs. Appreciate your support.

I'm afraid the link you've posted isn't working though - is there any chance you can double-check it's correct and if not, repost it?

I'd really like to flag it with Google as a safety concern straight away.
Many thanks

Hi there!

Thanks for posting in the community. I understand that one of your Nest Protects beeped every 60 seconds as if the batteries were low. It's concerning that after you replaced the batteries a second time, the batteries were scalding hot. That's definitely not the experience we want you to have. I appreciate all the efforts you've made to resolve this issue. No worries, help is here!
