What type of batteries do thermostats take

What model is my Honeywell thermostat? Flip the thermostat itself over and look for the model number, which should be printed somewhere on the back of the case. How do I change my thermostat battery? General steps are as follows: Flip up or pull off the thermostat housing this is normally the hardest part. Locate the batteries. Take out the old batteries with your hand.

Digital wall thermostats are programmed to display a low battery warning one or two months prior to the battery going dead.
