I have an LED torch that gets its power from being wound up. It has died, a=
nd now won't charge up by winding, well winding produces voltage, but it wo=
n't retain charge. Had a look inside it, the generator produces about 12V w=
hen wound, but the capacitor looking piece immediately drops back to about =
3V when you stop winding.

Does anyone know what is used for energy storage in these? The device in it=
 looks like a capacitor, marked=20

3.6V 80mAh
12hr 8ma

>From the way the voltage across it drops back to almost nothing I'm guessi=
ng it has gone AWOL.
