Powerbook G3 Wallstreet Battery Option

[therieau]

Since this is absolutely the place to contemplate this question, I've been thinking about how to make my Wallstreet mobile again. I had a thought:

What if you took the innards out of an existing dead battery pack and installed a cheap USB power bank in the case and used it in the slot? Could you run the machine with just the power leads connected, or would it complain if it didn't see anything connected to the charging pins? Would the machine be able to tell the level of charge just from the power output?

Basically, does anyone have a schematic for the charging system I can review before I spend any money?

I look forward to hearing your thoughts.

EDIT: By the way, has anybody used these guys? http://laptoprescue.com/Powerbook-Battery/

Does anybody have an idea what voltages are expected on each of the battery pins?

Well, I'd imagine that the PowerBook is looking for far more than 5V, unfortunately. Couldn't tell you what the pinout of the battery connector is though.

Check the service source for it. Look for battery verification or something like that.

The only information I've found is from a third-party vendor selling replacement batteries for eleventy-million dollars. I'd rather be able to create a sled that I can slot a Bosch cordless drill battery into that will supply voltage to the machine and status to the indicator on the side. Maybe a mechanical button extension and optical fibers will do the trick there.
