Capacitor Battery Charger Circuit. Capacitance is a measure of how much energy can be stored in a capacitor. A rule of thumb is that your charge current in amps shouldn t exceed the capacity in ah of the battery you are trying to charge.
Set the voltage divider potentiometer to the highest resistance. We then use a lm317 to regulate 5 5v to charge our capacitor. The reason for the input capacitor is to ensure that the chip is stable and doesn t oscillate.
Never touch the charger circuit the battery terminals or the charge leads once it s plugged in to the mains supply.

Capacitors have two storage variables. In other words the ground symbol is the negative common wire for all of the circuit blocks.
