For those of you who might be interested in this offering from Battery Hookup.
The Battery Hookup Ad says (in part): "MOST CUSTOMERS REPORT THAT THEY SALVAGED OVER 95% OF THE CELLS. SOME CELLS MAY BE LOW VOLTAGE BUT MOST WILL TAKE A CHARGE. WE HAVE BEEN BREAKING DOWN AND TESTING TOOL BATTERIES FOR A LONG TIME. MOST CELLS TEST BETWEEN 80-100% CAPACITY AND A SMALL PERCENTAGE OF CELLS WILL BE BAD BUT NOT MANY AND THE CELLS THAT ARE LOW VOLTAGE YOU CAN APPLY SMALL POWER TO WAKE THEM UP AND MOST WILL RECOVER. CERTAINLY BETTER RESULTS THAN TESTING DEAD LAPTOP PACKS."
I purchased 20 lbs. of these "Mixed Tool Batteries" and here are my initial results.
Of the 21 battery packs they sent me:
(15) - Ryobi 18V (5 cells per pack)
(1) - Makita 18V (5 cell)
(1) - Makita 18V (10 cell)
(1) - Ridgid 18V (5 cells)
(1) - Dewalt 20V (5 cells)
(1) - Interstate 18V (10 cells)
(1) - Hoover 18V (5 cells)
TOTAL - 115 Cells
Of note, all of the Ryobi packs had the outer case screws removed.
Not sure why as all of the other packs had their screws intact, but it was nice to not have to remove them.
VOLTAGE RESULTS: (Fluke 117)
Ryobi Pack #1 LGDAHA11865 (0.581V) (0.607V) (3.429V) (3.285V) (0.599V)

Ryobi Pack #5 INR18650-15M M (-0.015V) (-0.001V) (0.000V) (1.118V) (1.171V)
Ryobi Pack #6 The inside of this battery looked like it had spent time in the bottom of a lake and was so corroded that I did not even bother with it.
Ryobi Pack #7 INR18650-15M M (0.000V) (0.000V) (0.000V) (0.733V) (0.769V)
Ryobi Pack #8 INR18650-15M M (-0.030V) (-0.020V) (0.021V) (0.527V) (0.800V)
Ryobi Pack #9 INR18650-15M M (0.000V) (0.000V) (0.000V) (0..877V) (0.930V)
Ryobi Pack #10 INR18650-13Q M (0.000V) (0.000V) (0.000V) (0.000V) (0.000V)
Ryobi Pack #11 LGDAHA11865 (-0.003V) (0.001V) (0.000V) (0.007V) (-0.004V)
Ryobi Pack #12 LGDAHA11865 (0.000V) (0.000V) (1.213V) (1.082V) (0.008V)
Ryobi Pack #13 LGDAHA11865 (0.008V) (0.009V) (0.016V) (0.010V) (0.013V)
Ryobi Pack #14 LGDAHA11865 (0.487V) (0.515V) (0.810V) (3.513V) (3.514V)
Ryobi Pack #15 LGDAHA11865 (3.565V) (3.554V) (0.519V) (0.734V) (0.653V)
Makita Pack #1 SE US18650VT (3.961V) (3.949V) (3.960V) (3.958V) (3.960V)
Makita Pack #2 SE US18650V All 10 cells were 0.000V and the positive ends were very corroded and a couple had holes in them.
Ridgid 18V SE US18650VT (3.930V) (3.938V) (3.930V) (3.937V) (3.934V)
Dewalt 20V INR18650-13B M (3.952V) (3.720V) (3.662V) (0.000V) (0.000V)
Interstate 18V INR18650-15K M (4.036V) (4.018V) (4037V) (4.038V) (4.036V) (4.038V) (4.036V) (4.036V) (4.036V) (4.036V)
Hoover 18V INR18650-20Q M (0.006V) (0.005V) (0.006V) (0.006V)(0.008V)
Of note: Not sure why some of the cells read a negative voltage. I had the leads on the correct ends.
Summary of cell voltages:
(10) > 4V
(18) 3V<4V
(0) 2V<3V
(15) 1V<2V
(52) 0V<1V
(15) Completely unsalvageable
I don't know if the (15) Cells that were less than 2V or the (52) cells that were less than 1V down to 0V will "wake up" or not or even if they do will they be worth anything but I will go through the process and find out and maybe I will come back and update this post once I do. Regardless I will not use them in anything important.
CONCLUSION: Even though these were only $12/lb (+ shipping), to only recover (28) cells that were in the proper voltage range is a bit disappointing.
