Upon integrating Equation (ref{5.19.2}), we obtain [Q=CV left ( 1-e^{-t/(RC)} right ).label{5.19.3}] Thus the charge on the capacitor asymptotically approaches its final value (CV), reaching 63% (1 -e-1) of the final value in time (RC) and half of the final value in time (RC ln 2 = 0.6931, RC).. The potential difference across the plates increases at the same rate.

batteries
In charging mode, after the cell has reached 4.2 V, the charger goes to CV mode, and after this, charging ends (based on cut-off current). As I understand it: in CV mode the battery chemistry stabilizes; due to this we may get good capacity and life cycle.
At what current should I charge a LiPo battery?
2000 mAh battery charging @ 2c = 4.0 A charging current; 2000 mAh battery charging @ 0.5c = 1.0 A charging current; Charging at higher currents ... 1c.

And there''s not really any reason to do this, but ...
Battery not charging with shore power
It''s kind of intuitive that if 14.4V is 100%, 13.8V is well short of 100%, but unfortunately that''s not how lithium charging works. Pushing the battery to 14.4V is done only to quicken the charge. I.e., get the current up to 40-50 amps (in the case of the 8955) for faster charging. Then when voltage hits 14.4V, voltage is dropped to 13.6V to ...
batteries
In your particular case, the reason there were no "dramatic effects," is that the battery and the capacitor have internal resistance. Therefore, the capacitor will not instantly charge up to the battery voltage. It will "slowly" charge up at the "normal" rate specified by the product of Rint and the capacitance C.
