Edit 1530 Eastern: OK, first runs: Tench boat
Ahead Flank at 0900 hours Day 1
Boat slowed to 2knots @ 1300
Battery discharged to 4% at 1600
Surfaced and begin charge at Ahead Standard
Battery charged to 50% at 1030 hours Day 2
Battery charded to 75% at 2300 hours
Battery @ 100% 1430 Day 3
Gato boat
Ahead Flank at 0900 hours Day 1
Battery 4% discharged at 1600 hours
Surfaced and Ahead Standard @ 0600 hours Day 2
Battery re-charged to 25% at 1430
Battery charged to 50% at 0115 Day 3
Battery charged to 75% at 1345
Battery fully charged at 100% 0515 Day 4 Now, I never did get either boat to fully discharge, not for lack of trying. With the Tench, I didn't try very long. With the Gato, I did, hence the difference between the 4% charge, which is where the game states "Battery fully discharged" at 1400, and not surfacing until 0600 hours the next day, and we were still on a 2% charge, boat still doing 2 knots, telegraph still on Ahead Flank...
Charge times for Tench 18 hours to 50%, Gato 18 hours and 45 minutes, which could well be a function of the TC used, and the fact that the Gato battery was taken down to 2% for a much longer period of time than the Tench boat's was. the 75% to 100% figures are Tench at 15 and a half hours, Gato at 14 and a half hours. Again, could be the TC used - OR - horrors, my math... as a little side-note, I almost did not graduate from high school... 'Course, that was a little something more than just grades  ... Anyway. There are my first runs. I am in a bit of a hurry, with several more things to do today, so it will be a while before I re-visit this.

Thanks propbeanie, as usual you've outdone yourself!!
So, if
MY math is right. The Tench took 46:30 hours to recharge from a 4% capacity battery, @ an "Ahead Standard" speed. The Gato took 47:15 hours to recharge from a 2% capacity battery, at the same engine setting. That sounds about right since both subs have the same propulsion setup.
I just finished monkeying around with some figures and did a test with a Porpoise. I went down to 10% battery capacity, then began my recharge with an "Ahead 1/3rd" engine speed. At the more conservative engine speed, I was able to get 100% recharged after 24:00 hours flat.
So, three things....we need to be on the same page regarding what recharge speed we should use.
Second, I think my tweaking may have produced
some of the difference between your recharge time and mine. Although my "Ahead 1/3rd" producing a 3 kt travel speed was putting more energy back into the batteries than a 11 kt "Ahead Standard" speed would.
Third, make sure you've got the Option "Limited Batteries" checkmarked.
I'll "tweaked" some more and will test again.
