C cells seem a bit OTT

Why does it?


Because C cells were for larger short curent usage, those and D cells were standard in the days you had to drive a mechanical a solendiod that hit two bells alterantively.


Bing bong!

That doesn't indicate recharchable cells are required.


Correct.

Cs & Ds were used for long life with interminatend discharge.


Correct.

It just seems a bit of a waste to use C recharables that's all.


You sound like a Brexiteer ... jumping to conclusions without any idea
of the facts (it seems). ;-(


I have the facts and those are that rechargable battereis arenl;t really an effcicinet power source for door bells it overkill it's like building a nuclear generator in yuor home to recharge the batteries. Can be done of course but not very logical.



you could use rechargble AAAs

I don't need to, I can use the rechargeable C cells?


OK for me they'd have seemed a bit pricey for the use they are put to.


Pricier than multiple alkaline cells?


YES. about 10X partly because you need 2 sets one in use the other being charged.



We have over a dozen DMMs we stopped using partly because they used 6 X C cells.
C cells are about 4x the price of AA/AAA.


And one set of alkaline can be more expensive than the same in Ni-Mh.


I've never seen that price structure of course if you order your alkaline AAs gift wrapped from harrods you may well be paying more than most do for their rechargable Cs but most won't be doing that.



you could also use a solar panel to recharge the batteries.

I could, but it's much easier just recharging them as required than
buying, fitting and wiring a solar panel.


So you need 4 in the bell unit


Correct.

and 4 on charge


'On charge'? No, charged when taken out and re-charged just before
they replace the old ones.


soi two sets as I said.


that's about £30+ worth of batteries just seems a lot to me.


Yes, it would be at your prices.


Well where do you get 8 recharble C cells from .
