What Type Of Batteries Does The EcobeeThermostats Use?
Ecobee thermostats use a single 3 Volt CR-2032 battery. It is a common non-rechargeable coin cell battery that uses lithium chemistry. The CR means lithium-ion chemistry ( C ) and rounded shape ( R ), and 2032 shows a diameter of 20mm and a height of 3.2 mm. The newer models of Ecobee thermostat batteries use CR 2477 batteries.
- Panasonic CR2032 batteries are engineered to provide reliable long-lasting power
- Reliable even in a wide range of operating temperatures (14°F to 140°F)
- These Panasonic CR2032 batteries and packaging meet or exceed IEC 60086-4 2019 ANSI c18-3m part 2-2019 and UL 1642 compliance standards
- Long shelf life of up to 8 years
- 3. 0 V nominal voltage
They are both small coined shaped batteries with the CR 2477 slight batteries. They are non-rechargeable and should be properly disposed of after use, preferably recycled.
How Long Do Ecobee Thermostat Batteries Last?
The 3 Volt CR-2032 lasts up to two years, and the CR 2477 batteries last longer for up to five years. They are not rechargeable, so you cannot reuse them when the power is completely expended.

How To Fix Your Ecobee Thermostat When It Is Not Cooling
- Confirm the settings
- Check for a blown fuse
- Inspect the wiring
- Inspect the AC filters and drain lines
- Check if the coil is dirty
Confirm The Settings
Confirm if the thermostat is set to cool mode or not. It may have been a pure case of omission. You can confirm from your phone or tab with the Ecobee app to see if it is in cool mode. If it is correctly set but does not respond, have a technician check it or follow all the steps below before you do so.
Check For A Blown Fuse.
Fuses protect the device from a power surge, preventing fires or explosions. To check the fuse, turn off the breaker to the house and check if it is a blown fuse. If blown, it is easy to replace, so discard the bad fuse and replace it with a new fuse.
Inspect The Wiring
Wear and tear on the wiring can affect the connection, impeding response to command due to difficulty in the current flow. Unmount the thermostat and call a technician to handle it.
Inspect The AC Filters And Draw Lines
Running your HVAC system will make dust accumulate in the filters. The AC filter is located on the unit, so you might want to leave checking and replacing it to technicians. Drain lines can also collect moisture and clog it up. Use distilled vinegar to clear the debris by pouring it down the drain pipe. Reattach the clean drain pipe and test the thermostat to see if it works.
Check If The Coil Is Dirty
Copper is a conductive metal prone to rusting, so it is expected to rust in contact with moisture. Corrosion on the copper coils could be a reason the cooling setting is inefficient. Get help from a technician to clean or replace the coil.
Final Thoughts
Ecobee thermostats are the recent, sleek, and tech-savvy thermostats of the modern time. Investing in an Ecobee thermostat is a great idea. It is a good investment and reduces how much work you must do to keep your home in a balanced climate.
