Honeywell Thermostat Battery Replacement- A Complete Guide to Replace

A Honeywell Thermostat Battery replacement requires a new battery once a year, and you'll begin receiving notifications 60 days before the battery needs to be changed. You have ample time to change the batteries.

The LED panel on the thermostat begins to display Low Batt or Replace the battery. You receive this first notification approximately 60 days before your battery dies. A different warning, though, is the black screen, and your thermostat ceases functioning after such warning.
 
You might not be concerned about changing the batteries in your thermostat if it merely uses batteries as an additional backup. You still need to replace the battery, though, as this could cause modifications to the Honeywell thermostat's Date and Time settings. But trust me, even your thermostat uses batteries for the backups.

What kind of Battery is Used by Honeywell Thermostat?

Nowadays, AAA batteries were required for the majority of Honeywell Thermostat models, however, some versions still require AA batteries. Therefore, before beginning the process of changing the batteries, always be sure of what batteries you require.

Another drawback is that while a few of the newest thermostats include sliding battery compartments, some do not, necessitating the opening of the cover plate in order to access the battery pack. You can accomplish this by carefully pulling the cover plate away from the base plate of the thermostat.

You might have to remove a few screws if necessary. Additionally, be careful to switch off the electricity before you begin changing the batteries to avoid coming into contact with any live wires.

How to Check the Model Number on a Honeywell Thermostat

Step 7: These thermostats are simple to replace because the battery compartment slips out.

Step 8: Switch off both the thermostat and also the circuit breaker.

Step 9: To replace the battery holder, push then pull the bottom cover.

Step 10: Place some AA batteries inside the battery compartment after sliding it out.
