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 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.

I'm looking to buy this system but only if I can use rechargeable batteries. Is the cut-off voltage really around 1.2v? If this is the case then they are going to be pretty wasteful on standard alkaline batteries too.
They do work but I find the standard rechargable NiMH batteries don’t last long. I’m thinking of either buying some non rechargeable lithium AA or rechargeable LI-ion AA (but these ones require a different charger).
The only way (I suppose) is to find and use rechargeable batteries that are 1.5V - that's the voltage per AA batteries.
Not good Tado have addressed this issue to some degree a long time ago
I'm trying them as an experiment - I'd rather recharge every month than keep buying disposable. When fully charged they register as low, but as a low reading battery can last for months anyway I'm going to try it out.
Same here, I'm still using rechargeable batteries but they won't last long, I would say 2 weeks at max during winter/heavy use.
So my brand new, fully charged Philips batteries managed 2 hours....
I ended up buying the non rechargable lithium AA’s 5 months ago and still showing fully charged on each thermostat.
