How to Replace a Thermostat Battery

The digital display on most modern thermostats is powered by replaceable batteries. Some units have a low battery indicator to let you know when to replace the batteries, but it is a good practice to replace the batteries once a year to insure the thermostat will not malfunction due to low battery power. Replacing the batteries more often also prevents older batteries from leaking and damaging the thermostat.
