Devices that run on batteries often need a replacement depending on how you are using them. If you use them on a daily basis, then the batteries will run out much sooner but if not, the batteries may last.

Do you use your thermostat on a daily, weekly or monthly? Your answer will determine how long the batteries will last. The good news is that you only need to replace the battery once a year for most Honeywell thermostats.

So, when is the right time to replace the batteries on your thermostat? Just 60 days before the battery runs out, you will start receiving notifications on the LED display of the thermostat. It will show “Low bat or “replace the bat” on the screen. This is to notify you that you need to replace its batteries as soon as you can.

Once the display goes blank or black, then the batteries are completely dead and your thermostat will not work anymore until you replace the batteries. If your thermostat uses battery as the only backup then its time and date settings will change once it goes off.

Thus, you need to get new batteries for your Honeywell thermostat as soon as you receive the low battery notification 60 days prior. Soon after you replace the batteries, the notifications will automatically disappear.
