I went through my house and changed all of the batteries in all of the thermostats and some of them are already showing a low battery message and the heater doesn't seem to be working. If I take out the battery pack and immediately put it back in it acts like its working for a few minutes but eventually goes back to reading low battery. Any ideas?
thermostat always show low battery

The thermostat is pulling excessive current from the batteries and that lowers the battery voltage and so gives you a false "low batt" reading?
Check the current draw from the installed batteries with a multimeter or
have the batteries that read low checked in a hardware store or drug store battery checker.

Here's one version of a tester

Could also be corrosion on the battery terminals in the 'stat, causing high resistance.
