Summary:
The Nest thermostat comes with a rechargeable lithium-ion battery backup that kicks in when the power goes out. However, this battery backup only lasts for a couple of hours before the thermostat shuts down completely. The thermostat uses 2 standard AAA alkaline batteries which need to be replaced when they are low. The battery power level can be checked on the thermostat or in the Home app. Recharging the Nest thermostat usually takes around half an hour, but it can take up to 2 hours if the battery is fully drained. When the Nest battery dies, the thermostat will turn off Wi-Fi, the display, and other features to preserve battery life, but it should automatically turn on once it’s connected to the system and powered up or if new batteries are inserted. With the power on, the Nest will typically charge itself, but it may take several hours if the power has been off for a day or two. If the power goes out, the Nest thermostat may not turn on and the batteries could have drained. If the battery of the Nest Detect starts getting low, the Nest app will notify you, and the Nest Guard’s Info button will light up and make an announcement. You can also manually check for a low battery status using the Nest app. Some common symptoms that indicate a replacement may be needed for the Nest thermostat include system malfunctions or abnormalities, which may require professional maintenance.
