Smallest Rechargeable Batteries

[Richb007]

Hi experts,
Can you advise and point me in the direction of the smallest rechargeable battery available.
I am trying to make a devise and need them to power a LED and bluetooth module.
Many Thanks

What sort of voltage and current are we talking?
If you want REALLY tiny then there's THESE but not really practical. Take a look at the RS web site and use the pull down menus to narrow your selection down.

My MIL has some rechargeable hearing aids that must use a tiny battery, that might do?

You could take apart some rechargeable earbuds.
