How to charge a battery capacitor
That fact that the battery may also store that much energy does not mean that there is a capacitor equivalent to a battery. While an ideal battery maintains the voltage across its terminals until the stored energy is exhausted, the voltage across an ideal capacitor will gradually approach zero as the stored energy is depleted. - Download [PDF]

How to Charge a Capacitor
This may be a battery or a DC power supply. Once the capacitor is connected to the DC voltage source, it will charge up to the voltage that the DC voltage source is outputting. So, if a capacitor is connected to a 9-volt battery, it will charge up to 9 volts. If a capacitor is connected to a DC power supply outputting 15 volts, it will charge ...
Charging of a capacitor by battery
Since the initial voltage across the capacitor is zero, no work is initially required to move the charge. As the voltage increases, the work required increases. But the maximum work per unit charge the battery can do is its own emf, which is why charging stops when the capacitor voltage equals the emf of the battery.
How to Charge Capacitor Without Resistor?
The easiest way to charge a capacitor is by using a battery.
