Chirping even after new batteries

[augustberkshire]

My Nest smoke detector is 5 years old but it’s supposed to be good for 10 years. It has started chirping occasionally. The batteries checked out as still good but I replaced them anyway. The chirping continues. Even when I remove the unit from the ceiling there is still chirping from the base in the ceiling. What’s wrong?

If the replacements are energizer lithium, you've exhausted your troubleshooting. Request a warranty replacement, but be prepared to wait months if anyone actually responds. 

In the meantime, Report this issue to the Consumer Product Safety Commission as it is a commonly reported issue that Google has failed to address or acknowledge internally. https://www.saferproducts.gov/IncidentReporting

It turned out not to be a problem with this product at all. It’s fine.

It wasn't the Nest that was chirping after all. It was another nearby sensor that's hidden so we had forgotten about it. I wish I could delete my original post.
