I have a solid state "gizmo" that is producing 2.250 volts DC and is lighting (dimly) a LED. But the unit is "floating" on a rechargeable battery. (It's been running for months under a Faraday Cage) See attached diagram.
The LED goes out when I try to remove the battery.
I calculate that the gizmo is producing 4.5 milliwatts based on the voltage x .002 amps minimum to keep the LED lit.
Question: What size capacitor do I need to replace the battery?
Thanks!
