Charge and Discharge
Once the battery and capacitor voltages are equal we can say that the capacitor has reached its maximum charge. If the battery is now disconnected by opening the switch, the capacitor will remain in a charged state, with a voltage equal to the battery voltage, and provided that no current flows, it should remain charged indefinitely.

It does not mean, it can hold a fixed voltage against any external force. In fact a capacitor does in no way keep a voltage. The voltage of a capacitor reflects its current charge! And it reflects it linearily: $ U=q/C $ How does charge change? A current flows through the terminals of a capacitor, and the charge changes. Hence the voltage ...

How to Discharge a Capacitor
To calculate one time period for charging and discharging capacitors, you use the formula: τ=RC, where R = Resistance (Ω) and C = Capacitance (Farads). When you see a capacitance with a "µF" rating, understand that it represents microfarad. 1µF = 0.000001F.
Can a capacitor charge and discharge at the same time?
No, the charge on a capacitor is increasing (charging), decreasing (discharging) or remaining the same. There are no other possible states (assuming an ideal capacitor with no leakage). When the capacitor is charging or discharging, there is a potential difference between the two terminals and apparent current flow.
