when a capacitor reaches it, it acts as a battery
If you use AC components (i.e. inductor or capacitor ) on DC circuit, they will initially behave different than at steady state. Steady state is the state in which the behavior is not changing with time. (theoretically after infinite time, practically within small time any ckt reaches steady state)
ideally there will not be any resistance to the capacitor,so at this condition it should not not discharge the stored energy. but practically small resistance will be there in the capacitor so the energy stored by the capacitor will be discharged through resistance.
To evaluate the transient response of an RC circuit, you start with the steady state just prior to the transient, i.e. just prior to the switch being opened or closed, or just prior to whatever transient event you are modeling. Since you are steady state, assume that capacitors are not present, i.e. they are resistors with infinite impedance. Calculate the voltage and current at each node, using Ohm's law and/or Kirchoff's law and/or Norton/Thevanin equivalents as necessary. Remember that capacitors resist a change in voltage. The equation is dv/dt = i/c. At t=0, assume that each capacitor has the voltage calculated from the initial steady state condition. Initiate the transient and calculate the voltage and current at each node using the initial state differential equation. You can do this analytically, or you can model it in software. If you model, pick an appropriate delta-T, and do a step wise evaluation until the voltages and current settle to their new values. Adjust delta-T to make sure that you are getting consistent results. Just don't go too short, as truncation error can bias the results.
A resistor or an inductor. The inductor limits transient current, not steady state current.
A resistor is used to limit current flow through a capacitor.If you did not use the resistor, you could potentially create large currents through the capacitor, damaging it. Capacitors do have current limit ratings - check the specification sheet for the capacitor.Also, in the case of an electrolytic capacitor, if it is generally in a discharged state then it is necessary from time to time to reform it. That process involved slowly charging it, i.e. through a resistor, and then letting it discharge by itself with no or little load. The resistor protects both the capacitor and the voltage source in the case that the capacitor might be shorted.
It then declines

An inductor looks like a piece of wire to DC. It will thus look like a resistor, and inductor properties do not apply.
-- If the excitation source is AC, then the steady state of the circuit depends on the voltage, frequency, and waveform (harmonic content) of the source. -- If the excitation source is DC, then the steady state current in a series circuit is zero. DC doesn't pass through a capacitor.
A change of state will occur.
ideally there will not be any resistance to the capacitor,so at this condition it should not not discharge the stored energy. but practically small resistance will be there in the capacitor so the energy stored by the capacitor will be discharged through resistance.
Steady state gain,
Capacitors do not get "full" like a glass of water. The current into a capacitor is the rate of change of charge, so it's equal to C * dV/dt or something. If the voltage is constant, there's no current. If the voltage on both sides of the resistor is the same, there's no current through the resistor and hence into the capacitor, so that's the steady-state - what you call "full" - the capacitor charged to the supply voltage.
Yes, capacitors can be, and often are, used in DC circuits. At steady state DC conditions, the capacitor has near infinite impedance. Its value is in its ability to resist changes in voltage, so it can serve as a transient filter. There is almost always a small ceramic capacitor connected between VCC and ground next to IC's in a digital circuit, for that exact purpose.
steady state is a condition when the temperature neither increases nor decreases.....
what is steady state flow process in fluid dynamics
The steady-state theory is obsolete - it is now known that the Universe does change over time (the Steady-State Theory states that it doesn't). According to the Steady-State Theory, the Universe has no beginning and no end.
