It sounds like there was a bit of confusion earlier, so let's clear that up about the battery life of the Google Nest Protect.
For the battery-operated version, the manufacturer says the batteries can last up to 5 years, using six AA lithium batteries. But keep in mind, actual battery life can vary depending on factors like how often it's used, its Wi-Fi connection, and how many alarms it triggers.
If you're thinking about the wired version, it has a battery backup. The manufacturer mentions that these batteries last for several years under typical conditions because they're used mainly for power outages.
Based on our research, most folks seem pretty happy with how long the batteries last, even if they use the device a lot. Plus, the Nest Protect will alert you through the app and give a little chirp when it's time to change the batteries, so you don’t need to worry about forgetting to check.
The convenient notifications sent to your phone also help as a reminder when a battery replacement is needed, integrating well with the smart features of the Nest Protect.
It's a good idea to use high-quality lithium batteries for longer-lasting performance and reliability, especially in different temperature conditions.
Regular checks through the app will keep you informed about the device’s status without much hassle.
