How to Use a Charged Capacitor to Light an LED
When the button is pressed down, closing the circuit, the battery does two jobs: it charges the capacitor up with voltage and it gives power to the LED, lighting it. Once the battery is on for enough time for the capacitor to be fully charged up to 9 volts, the capacitor cannot retain any more charge. This happens in a matter of seconds.
How to Quickly and Safely Charge Supercapacitors
as previously discussed. Li-ion batteries are recommended to have charge termination and not be continuously topped off, for example, not be recharged until the battery discharges by a nominal amount (at least 200 mV). Supercapacitors typically do not need
