How To Change Batteries Honeywell Thermostat

If your Honeywell thermostat is having trouble starting up, or if the display is flickering, it may be time to change the batteries. Here’s how to do it:

1. Turn off the power to your thermostat at the breaker box. This is an important step because you want to ensure that you don’t accidentally short-circuit anything while changing the batteries.
2. Remove the faceplate from the wall. For most models, you will need to gently pull the bottom of the faceplate away from the mounting plate. If your model has screws, unscrew them first before removing the faceplate.
3. Locate the batteries inside the thermostat. There will typically be two AA or AAA batteries inside. You may also see a wire connected to one of the batteries – this is normal and is used as a backup power source in case of a power outage.
4. Remove the old batteries and insert new ones in their place, being careful to observe correct polarity (positive + and negative -). If there was a wire connected to one of the old batteries, simply reconnect it to the new battery in the same spot.
5. Replace the front cover of your thermostat and reattach any screws that were holding it in place. Once everything is back together, go to the final step.
6. Turn the power back on at the breaker box and test your thermostat to make sure it’s working properly.

Replacing Your Honeywell Thermostat Battery Tips:

1. Know that some newer WiFi-enabled thermostats do not require batteries as they are powered by a C Wire. Check your model’s documentation to see if this is the case for you.
2. If your Honeywell thermostat runs on AA or AAA batteries, we recommend using alkaline batteries as they tend to have a longer lifespan than other types of batteries.
3. Be sure to write down the current settings on your thermostat before you remove the faceplate. This way, you can easily reset them after changing the batteries.
4. Gently pull the bottom of the faceplate to remove it from the wallplate. Be careful and watch to ensure you are not also pulling the wallplate away from the wall.
5. If you need support, contact Honeywell US Customer Care at 1-800-468-1502.

When Should You Change the Honeywell Thermostat Battery?

Most thermostats will display and flash “Lo Batt” or “Replace Batt” 60 days before the batteries run out.

The general rule of thumb is to change your batteries once per year, but this may vary depending on the model of your thermostat and the type of battery it uses.

If your thermostat uses AA or AAA batteries, you will probably need to replace them every 1-2 years. If your thermostat uses a lithium battery, you may only need to replace it every 3 years.

You can check your owner’s manual for specific recommendations on how often to change the batteries in your model of the thermostat.

What Type of Battery Does a Honeywell Thermostat Use?

The type of battery your thermostat uses will depend on the model. Some models use AA or AAA batteries while others may use a lithium battery.

If your thermostat uses AA or AAA batteries, you can purchase these at most hardware stores or online. If your thermostat uses a lithium battery, you may need to order it directly from Honeywell or a similar manufacturer.
