Programmable thermostats run on batteries, and one way to make them last longer is to stay mindful of this fact. Changing the batteries on time and using high-quality ones are the best ways to keep your thermostat in top-notch condition.

Here’s everything you need to know about maintaining your thermostat’s batteries:

When is the Right Time to Change the Batteries?

Warning Display Sign

In most models, the display on the programmable thermostat indicates that the battery is low. It is displayed in the form of a sign or a flashing light on the unit. This sign is shown as a forewarning that within a month or two, the batteries will die.

This means you don’t have to run about panicked, trying to find batteries for your thermostat immediately. The warning usually shows weeks before. It’s best to change the batteries before they completely deplete.

Dead Batteries

You should know that your battery has died when your thermostat’s display goes from running just fine to completely dead, with a blank screen.

It goes without saying that by this point, the thermostat will stop controlling the HVAC system and can lead to muddled-up temperatures around the house. You can end up experiencing either excessive cooling in the home or excessive heating.

It might even end up turning the system off, and you would be left without any heating or cooling.

With these signs, you’d know that it’s time to change the batteries of your programmable thermostat.

HOW TO CHANGE THE BATTERIES OF A PROGRAMMABLE THERMOSTAT 

Changing the batteries of a programmable thermostat is very easy and can be done at home. You can usually figure it out by yourself; however, the method of changing batteries differs from model to model. It is better to refer to the manual and follow the instructions given.

In most of the models, the process is pretty straightforward. You’ll either need to remove the battery compartment or remove the thermostat from the wall first to access the battery compartment easily.

Some Tips to Maintain a Long Battery Life

  • Make sure you replace all the batteries at the same time. Old and new batteries shouldn’t be used in one device.
  • Whether it is AA batteries or AAA batteries required by the programmable thermostat, you have to make sure only to buy alkaline batteries.  
  • Use the same kind of batteries and do not mix batteries of different types in your programmable thermostat.
  • Heavy-duty batteries are often not suited for programmable thermostats. 

Follow the tips above and enjoy a long battery life, as well as the long life of your programmable thermostat.
