Hello all NG

I am looking for a fake AA battery, i.e. a conductor of the same size,
so that I can put it in an AA battery holder and have a lower voltage
(N-1 x 1.5V) . Actually I want multiple of them so that I can make a
"configurable voltage" battery.

I have looked around but I can't find it. Does anybody know any?

Alternatively I could look for a battery which can be charged at various
voltage levels, but it needs to hold a significant charge at any voltage
level. I don't think it exists.

Thanks for any help

How about this:
