While bounty farming for the last CG, my Python (6A shield, 3 A-rated boosters) had the shields down to this point:
So I always wondered, how slowly DO shields actually recharge? So started recharging. I also wanted to know, how fast is the power drained from the SYS doing this, and how many pips I needed to keep it charging.
The answer was simple. 1 full pip was enough to keep the SYS bar fully charged. 1 half pip very, very slowly drained the SYS.
It took this much on half a pip to drain the SYS to 1 bar
I refilled the whole thing again and started over. Finally, we reached the point where even half a pip did not drain the shields anymore - 100% reached
Now, everyone take a guess how long this took.
The last time I've seen this type of downtime was 15 years ago when playing EverQuest. I honestly don't think shields should recharge this slowly. Another observation I made was that it takes 3:20 to rebuild the collapsed shield. That puts it right at 50%. It also drains more power from the SYS, needs more than a full PIP to stay full. The other 50% then take 5:15? It would make more sense when your shield almost failed and you ended the fight to turn off your shield and turn it on again. Feels a lot like MS windows.
Why does a collapsed shield restore faster to 50% than a non-collapsed shield? In my opinion, shields should drain what's in the SYS capacitator and the recharge rate from there on out depends on how many pips you put into it. It should not drain around 15% of the full capacity of the shield. That's a massive bottleneck on shield recharge.
Ironically, shield cells used to be good for keeping your shield up out of combat, but since the ammo reduction on shield cell banks, you don't carry enough of those anymore.

10 minutes, 30 seconds. Also means the capcitator on 1/2 pip lasted for more than 3 minutes.
