Smart Rads power by rechargeable lithium ion AA batteries
I bought some Kentli brand it it does the job.
It is still in the early days to see how long it last before indeed to recharge them. But I am hopeful that we could all contribute to save the planet.
This should be an absolute must. Any rechargeable batteries with do for me.
Don't treat this as gospel but I believe that due to the different way Alkaline and Lion batteries discharge fitting a Lion battery to a device designed for an Alkaline would 'confuse' its ability to report how much capacity is left.
I would not expect this to prevent using them but you might have to ignore its estimate of charge left.0
thx Mytada for bringing up the lithium discussion. I was thinking myself about it too. I mean 1.5 Volts, same as the alkaline batteries, but rechargeable!
However Jelockwood brings up a good point with the discharge current. Tado gives only the advise to take "any" alkaline batteries, but I couldn't find anything about an appropriate discharge. But as there are Lithiums out there with 1.180 mAh as well as up to 3.000 mAh, it should be possible to find a suitable option, shouldn't it?
I would love to hear new insights about your test run, Mytado.
Kind regards, Mark0
The battery I am using is still working, no problem. A single charge has been running for 6 months now. But I have decided to recharge it as Tado will not warn me of a cliff edge voltage drop (a feature of the technology and battery). I recommend anyone to use it as it works and reduces the amount of waste to the planet!!0
How did anyone get on with Lithium Ion rechargeables for TRVs? The only thing I am not sure about is how it knows when they are running out, since they sustain a full 1.5v over use. I have just installed Tado but may try it on one TRV to see.0
I use rechargeables across the board and the workaround for me is basically just to have a reminder every 6 months just to recharge every battery in the house. Most of the time tado is reporting that the batteries are low when in fact they're working fine. A real oversight from their side because most people have no intention of filling landfill with dead batteries.0
I have just started going the same. NiMh work but they don't last long (probably a combination of current drop off and Tado reporting them low to early) and also they are often to thick to fit properly.
So I got these:
which promises 1.5v steady voltage, as much capacity as a good non-rechargeable, are nice and thin so fit properly.
I'll see how long they last and then, as someone else suggested, just recharge them on a fixed schedule.1
Tado seems to have updated the software and now the App will notify me that the battery is low on the lithium Ion battery.0
Hmm that is very interesting as I had first notification on normal batteries pack supplied with trrmostat after week of use so I decided to use Bonai HR6 Ni-MH 2800mAh, which I successfully was using in my camera flash.
As I was typing this decide to look closer on spec and found those are 1.2V rather 1.5V which would explainwhy I had messages 3 times from same unit.
I think I need to look for 1.5V set... 🤔0
