6x AA (lithium)
I first purchased one of these when the Nest Protect 2 was first released in 2015 (imported from the U.S). I was very impressed with the complete lack of false alarms and the fact it give you a "Heads up" warning if it detects anything. Great for the Kitchen. The batteries supplied with this device are very high quality and after 2+ years the original batteries are still fine. I have since purchased a second device.
The main downside is the cost - very expensive but recommended for the Kitchen at least.
Needs the App and Wifi to set up.
Yes, I recommend this product.
