Nest Thermostat Batteries (All You Need To Know).

Author Adam B Published on 3 min read

The Nest thermostat allows you to control your HVAC system via your mobile phone, offers features to help reduce energy consumption, lets you set a schedule, and programs the temperature as you like.

This thermostat relies on batteries to get a sustainable amount of power to run your HVAC system year-round and your device’s battery life varies depending on which model of thermostat you’re using.

In the following sections, we’ll learn more about Nest thermostat batteries and discuss things like lifespan, type of batteries, how to replace them, and best practices for getting the most out of them, so keep reading.

What type of batteries does the Nest Thermostat use?

The Google Nest thermostat mirror version uses 2 standard 1.5 V AAA alkaline batteries as a backup, or to supplement if your HVAC system can’t deliver enough power (so it’s a secondary power source).

According to some sources on the internet, These AAA alkaline batteries can last from five to ten years and you’ll need to replace them when you receive a notification telling you that your batteries are low (You can also check their levels on Google Home app or directly on the device).

And if you’re using Google Nest Thermostat E or Google Nest Learning Thermostat it’s different because they use a Lithium-Ion rechargeable battery.

Unlike an alkaline battery, lithium-ion cannot be replaced by the user and it is designed to continually charge and discharge as needed throughout the life of the thermostat (According to some sources, the typical estimated life for a lithium-ion battery is about two to three years or 300 to 500 charge cycles).

The lithium-ion battery is charged from the thermostat’s wire, so make sure the wires are installed correctly (turn off the power when checking the wires to avoid an electrical shock), or the battery won’t get enough power and the thermostat will stop working.

Tips to get the most out of your Nest thermostat batteries.

No matter the version of the Nest thermostat you have there are always tips and best practices to reduce the consumption of your battery, avoid fast drains and make it last longer.

The following instructions will help you achieve that goal.

  • Boost Wifi Signals: When your Nest Thermostat is too far from your router, Wi-Fi signals will be weak and it will use more battery resources to maintain a good connection.

    So be sure to boost your Wi-Fi signals to provide a stable connection and improve your battery life.
  • Operating temperature: The thermostat batteries are affected by ambient temperature, so make sure the temperature in the area where the thermostat is installed is neither too low nor too high (also make sure the device isn’t exposed to the sun).

    Also, a high level of humidity allows moisture to enter the gadget and damage the battery.
  • Use batteries from good brands: When it’s time to replace the batteries, I recommend buying new ones from a reputable manufacturer because poor-quality batteries won’t last long.
  • Track battery usage: Checking the level of your battery periodically is a good step to do in order to treat the battery in a good way, make sure to not overcharge the thermostat, and do not wait for the battery to reach 0% before charging it.
  • Update the firmware: Old firmware can drain your battery faster due to errors and low performance, so updating it will enhance the performance of the thermostat and make it work smoothly without high energy consumption.

How to change Nest Thermostat batteries?

When the moment arrives to replace your batteries on the Nest thermostat, you won’t need a technician to do this because it is easy to do this yourself, all you need to do is to follow the instructions below:

  1. Pull the thermostat off the base.
  2. Remove the old batteries from the back of the thermostat.
  3. Insert the 2 new AAA alkaline batteries (Put the batteries in the correct positioning).
  4. Push the thermostat display back onto the base until it clicks into place.

Note: These instructions do not apply to the “Nest Learning Thermostat” and “Nest Thermostat E” because their battery is not replaceable.

Conclusion.
