6 FAQs about [How to use capacitors to repair batteries]
How to reform a capacitor?
The better way to reform such capacitor is by giving a controllable voltage at its rating point with a resistor in series. Then we can see the current movement inside the circuit with a Volt-meter across the resistor. Off course the best way is to use specific reformer device, like Sencore LC-102 (which I’m too lazy to power her up).
How to charge a capacitor?
The laziest way is by giving the capacitor a voltage (good if you can source an exact voltage with the capacitor’s rating). If not, using a lower one should be fine. I use 9V battery pack to charge the capacitor. My capacitor is rated at 25V though. Then we have to discharge the capacitor. You can use 100-220K resistor across the capacitor.
Should I use a battery or a capacitor?
It depends on the expected lifetime you need. If you are going to have more than tens of thousands of power fail events, then capacitors would assure you of a longer life, useful if it was an unattended situation like a remote island. However a battery would be so much smaller, cheaper and easier to use, that's the way I would go.
What happens if a capacitor has never been in a circuit?
Say you have a fresh capacitor that has never been in a circuit. When a voltage is applied across the capacitor's terminals, current will flow into one of the capacitor's plates, creating a build up of charge, and flow out of the other plate, creating a negative charge.
How many volts should a capacitor be rated for?
According to this answer, you'd want to use capacitors rated for 400-450V, since per unit volume they give you most energy stored. You'll want to charge them up to 95% of the rated operating voltage, and discharge them down to 50-100V.
Why are capacitors important?
That's where capacitors come into the picture. They are components that we make to give us a certain ability of charge storage so that we can better manipulate the transfer of electrical energy. Capacitors let us have better control over the storage of electrical energy. Capacitor Symbol
