The problem is that you can not connect an ideal voltage source of a given voltage in parallel with an ideal capacitor that has some initial voltage different from the source voltage. Once these two are connected, our definitions of "ideal voltage source" and "in parallel" demand that the voltage across the capacitor instantaneously changes.
Capacitors in Series and in Parallel. Multiple capacitors placed in series and/or parallel do not behave in the same manner as resistors.

Current can only flow in a closed loop, so a series capacitor cannot keep reactive current from flowing through the distribution grid, which is the very thing that power factor correction seeks to avoid in order to avoid the resistive losses of that current travelling long distances through practical conductors.

The charge stored in a capacitor is: W = 1/2 * C * V^2. For a capacitor in parallel with a 12V battery the total charge in the capacitor would be: W = 1/2 * 88 * 13.4^2 ---> 7900 Joules. But since the lowest voltage is the fully discharged level of the battery you can only access a portion of the stored energy:
2 · Capacitors in Parallel . Capacitors can be connected in two types which are in series and in parallel. If capacitors are connected one after the other in the form of a chain then it is in series. In series, the capacitance is less. When the capacitors are connected between two common points they are called to be connected in parallel.
