Radiator thermostat battery information :

When the time comes to replace your batteries in your Wiser Radiator Thermostat you may find that the batteries removed from the device are not fully depleted. The Wiser Radiator Thermostat requires a certain level of power to ensure that the motor operation is successful, when batteries deplete past a certain point there will not be enough power to drive the motor and the thermostat will show a low  battery symbol within the app.

However, the batteries removed from your radiator thermostats can still be used in other items which require a lower level of power, some examples of such are : TV remotes, clocks and even the Wiser Room Thermostats which can run until they are fully depleted.
