I am glad you posted this! I completely forgot I have a few 12DC PC fans. They are brushless, but it gave me something to try tonight.
The bad battery that I am using wouldn't take any thing more than 3.5V on my SSG, and as soon as I connected any load at all to it, even a joule thief, it would drop down to 1.5V or less, and die in a hurry.
when it is on the SSG charging, it would read 11-12V charge.

I hooked everything up as per Turion's first post (fan connected to pos of battery 1 and 3, neg of 1 connected to pos of 2, and neg of 2 connected to neg of 3) and the fan started right away, which I understand may not be a good thing, but oddly enough the bad battery (bat 3) is reading 17V and climbing at the moment when it is under load. when I remove the fan, I now get 4V and dropping, instead of the 3.5V I had seen on it previously as a high mark. Not sure what to make of it yet, but I am looking to connect a load to bat 3 and see what happens next
The fan is running, though no where near full power yet, and it has some LED's in it, which will flash off every few minutes. the fan doesn't seem to change speed when it happens, though it is hard to tell. Not sure what that means either. I will leave the test running for a while, monitor all three bat voltages, and post what happens.
Thanks for making that post FRC, you got me started at least!

I have connected a light bulb I pulled out of a drill press that stopped working to bat 3, to see what happens. With the bulb connected, The voltage on bat 3 drops to 14.5V and sort of stabilizes, though it does still show it climbing slowly. Batteries 1 and 2 don't seem to notice the extra load at all, and in fact, bat 1 gained a few mV after the bulb was connected. I do not get much light at all out of the bulb mind you, but it does glow ever so slightly...
Again, not sure if any of this even means anything, but I am trying to document it, in case it is helpful in any way
