Can I use re-chargeable batteries in my Wiser Radiator Thermostats and Wiser Room Thermostats? Follow
We advise against the use of re-chargeable batteries in the Wiser system, and recommend only the use of standard AA Alkaline batteries - non-rechargeable. This is due to the nature of re-chargeable batteries not being optimised for Wiser device system use.
Most standard rechargeable batteries have a lower starting voltage than conventional disposable batteries, which means the Wiser Radiator Thermostat will not get the voltage required to drive the motor as designed, leading to a system potentially behaving at sub-optimal levels.
