A Capacitor stores charge using a pair of parallel plates with an insulating material known as the dielectric separating them. When a current is applied to the capacitor, the electrons can't cross the dielectric so they build up on one side and leave the other, meaning the plates become charged. When the current is removed, the electrons flow back and the charge is reduced. The speed at which they do this is dependant on the size of resistor in the circuit.
A Battery (Cell) creates its own current through chemical reactions. There are two parts to a cell, each known as a half cell. Each half cell consists of an electrode, which is immersed in a solution. Copper and Zinc are common metals used for the electrodes. The solutions are usually made of the same substance in a compound which dissociates; the copper electrode would be immersed in, for example, a copper sulphate solution. An equilibrium is then established between the copper electrode and the dissociated copper ions, with the electrons flowing into the other half cell, creating a potential difference. This circuit is completed by a link between the two substances known as a salt bridge.
Capacitors are useful for fast charge storage over a short time period, though the rate at which they discharge is exponential. Batteries are useful for providing a slow, steady flow of electrons for much longer periods of time.
Hope this helps!
The charge in a capacitor is between the plates. The dielectric is only an insulator that allows the plates to be very close without touching and discharging the charge. There is no battery in a capacitor.
If the capacitor is charged then the battery will explode.
the charge on the capacitor had increased.

A car battery does not need a capacitor as it's regulating capacity (when in good condition) is well above any capacitor you can fit into your car.
when a capacitor reaches it, it acts as a battery
When a stereo system drains too much battery power, it is time to add a capacitor. The capacitor will not increase the battery, but instead will modulate it allowing for additional stereo usage.
The capacitor in a disposable camera fills up with power from the battery. It is then used to very quickly pulse the stored energy through the xenon flash tube bulb. The capacitor is capable of discharging all of it's energy almost instantly. A battery on the other hand can only discharge it's power slowly by comparison. So for the high power flash, we use a capacitor to give it that large jolt of power to produce the very bright flash. The "slow" battery then takes it's time (a few seconds) to recharge the capacitor for the next picture.
A capacitor that is suddenly connected to a battery will charge to the battery voltage. The time to do this is dependent on the current capacity of the battery and wiring, and the capacitance of the capacitor. This represents an instantaneous short circuit, which lasts for a (usually) very short time - but damage could be done if there was no resistance. A charged capacitor that is suddenly disconnected from a battery will hold that voltage. The length of time it will hold is dependent on how much leakage current there is.
For a long time, The capacitor will be charged to the voltage of the DC battery, the positive side of the capacitor touching the positive terminal of the battery. Not much DC current will conduct, except for some tiny leakage current due to imperfection of the cap. The battery will be drained eventually.
Capacitor
Depends on the size of the battery and the capacitor. If both are small enough to fit in your hand, then some fraction of a second.
