There are many different ways to test capacitors. Using a capacitance meter, using a DMM and an analog meter. In general, is it safe to assume that a capacitor is considered functional if it''s capacitance measurement is +- 20% of it''s declared value without doing the ohm/voltage test? Are these test overkill after the capacitance value has been verified?
What is "activate" mode on a 12v deep cycle charger?
Only place you hear the term Activate is in a good high end Deep Cycle Battery is when the batteries are shipped dry, and the acid is shipped in a different container. So in order to ACTIVATE a dry charged battery is to put the acid in, and then charge at 16 volts until charge current stops to Activate the battery. They do that mostly with Dealers.

But I wanted to know whether we can charge a capacitor while it is in use. If, by "while it is in use", you mean while the capacitor is discharging, i.e., energy is flowing out of the capacitor to some load, then the answer is no since, by definition, if a capacitor is charging, energy is flowing into the capacitor.

What is the difference between a battery and a charged capacitor?
A battery generates a voltage by a chemical reaction. There is a class of chemical reactions called redox reactions that involve the transport of electrons, and you can use the reaction to drive electrons through an external circuit. This is the basis of a battery. The battery will continue to provide power until all the reagents have been used up and the reaction stops.
6 Frequently Asked Questions about “Is it feasible to activate the battery with capacitor”
Does a capacitor help stabilize voltage?
The effective internal series resistance of a normal capacitor is much greater than the effective internal resistance of an automotive battery in good condition. That means that the capacitor will not help stabilize the voltage. But if the battery is an older second battery powering a high powered sound system then there may be a benefit.
What happens if an uncharged capacitor is connected directly to a battery?
In my understanding, theoretically, when an uncharged capacitor is connected directly to a battery of, let's say, 9 volts, instantly the capacitor will be charged and its voltage will also become 9V. This will happen because there is no resistance between the capacitor and the battery, so the variation of current by time will be infinite.
What happens if you put a capacitor on a battery?
This will happen because there is no resistance between the capacitor and the battery, so the variation of current by time will be infinite. Obviously, this is true when talking about ideal components and non-realistic circuits. I thought that doing it in real life would cause sparks, damaged components, explosions, or whatever.
Can a battery be connected directly to a capacitor?
However, I saw some videos and people usually do connect batteries directly with capacitors. Also, the current that flows from the battery to the capacitor is somehow of low magnitude, since it takes some considerable time to make the capacitor have the same voltage as the battery. I would like to know why this happens, thanks.
Why is the current flowing from a battery to a capacitor low?
Also, the current that flows from the battery to the capacitor is somehow of low magnitude, since it takes some considerable time to make the capacitor have the same voltage as the battery. I would like to know why this happens, thanks. This is an example of the circuit I talked about: Both the battery and the capacitor have an internal resistance.
Why does a capacitor take a long time to charge?
The reason it now takes time, is that when the capacitor charges, the voltage across the resistors decreases, so the current decreases as well, so the voltage on the capacitor will increase more slowly, and so on and so on, so it will actually approach the battery voltage slower and slower.
