Generally, once a year is enough if you're using high-quality batteries that are the correct type and voltage. This also applies to thermostats hardwired into your home's electrical system but use a battery as a backup power source.
Replacing the batteries of your thermostat is a simple and easy home maintenance task you can carry out yourself when necessary. As a rule, thermostat batteries will need to change about once every year. If you periodically change them, you shouldn't have any problems maintaining control of your thermostat.
The most obvious sign that you need to change your thermostat batteries is when the thermostat literally tells you the batteries are about to die! Most programmable models will now flash a low battery warning, usually about a month or two before the battery completely dies.
A: Research has shown that Duracell AA batteries can power a device for approximately 100 hours when they are in normal use in items such as flashlights and small toys.
Use High-Quality Batteries: Choose high-quality alkaline batteries for your thermostat. They tend to last longer and provide more consistent power than cheaper options.
Do Duracell Batteries Really Last Longer Than Energizer? In a battery life test conducted using non-rechargeable C batteries from the two brands in a flashlight, Duracell outdid Energizer. However, when a similar test was done using AA batteries in clocks, the Energizer AA batteries outlasted the Duracell AA batteries.
Increased Energy Bills: A malfunctioning thermostat due to a low battery can cause your HVAC system to run inefficiently, leading to higher energy bills. Inability to Adjust Settings: If you're unable to adjust the settings on your thermostat, it could be due to a low battery.
The following circumstances are common reasons why thermostats need to be reset: There has been a power outage. The batteries have been changed. HVAC filters have been cleaned or replaced.
The battery in the thermometer is almost consumed. If batteries are low on power, the display may show errors.
A thermostat can drain batteries if the unit is old or faulty. The temperature settings programmed into a digital wall thermostat don't impact battery usage (if you turn down the air conditioning in the summer, it won't save the thermostat's battery life; it will just reduce your energy bills).
The Lifespan of a Thermostat
On average, most thermostats last about 10 years, depending on the model, usage, and proper maintenance. However, many people decide to replace their unit sooner to take advantage of new energy-saving technologies.
Having a low battery can cause all kinds of bad readings on the thermostat, which means the thermostat may kick on when it's not supposed to, the room temperature may be incorrect, and the central system may not work at all.
Depending on your model of thermostat, most use AAA or AA batteries. We are now recommending switching to lithium batteries if possible, as they corrode less than standard alkaline batteries.
Instead of replacing batteries after 24 hours of use, you're always replacing them after only 12 hours. Some devices are sensitive to voltage. By combining an old and a new battery, the voltage will be lower and the device will be less effective.
It's always a good idea to have backups on hand, although it's best to change the batteries once a year.
If your thermostat is still turning up blank after inserting fresh, new batteries, then it might be time to check your heat and air conditioning systems. Sometimes, the transformer will stop sending voltage to run the thermostat. Start by checking the air conditioning safety switch, which is in the drain pan.
Locating the Reset Button
Remove the thermostat cover by either snapping it off or unscrewing it, depending on the model. Most modern thermostats will have a clearly marked reset button inside the panel. It's usually small and recessed, so you might need a pointed object like a paperclip to press it.
There are several tell-tale signs that your thermostat may be in need of a battery change. One of the most obvious is when the display becomes dim or unresponsive, meaning there is low battery power. This can also signal a dead battery.
That's a question we're asked often.
Generally , thermostat batteries last 8-12 months & help retain settings during power outages. Low batteries in digital thermostats are a common cause of issues preventing the heating and cooling system in your home from running.
Switch the batteries.
Remove the batteries, then install them backwards. Leave them that way for at least five seconds, then take the batteries out and put them back in the correct position. Close the battery door and check if the display is back–if it is, then you've just reset the thermostat successfully.
A bad thermostat can be detected when your AC or furnace is not turning on, your HVAC systems are not turning off, the thermostat not responding, your HVAC system is short-cycling, the room temperature not matching the temperature displayed on the thermostat, and the programmed setting resetting themselves.
Duracell AA: Highest price per unit, but the second-best performer and a close contender for the best pick. Rayovac AA: Second most costly AA battery with moderate performance. Not necessarily the top option available. Amazon Basics C: Lowest price per unit among C types, significantly cheaper than the competition.
The long-lasting performance of a Duracell battery is possible due to the modern technologies inside the battery. The primary technologies are: Duralock and High Density Core. Duralock keeps active materials inside the robust case and prevents leakage.
The Energizer® Ultimate Lithium™ batteries are the #1 longest-lasting AA batteries – complete with leak resistance and performance in extreme temperatures (-40ºF to 140ºF or -40ºC to 60ºC).
