Most USB charged modern devices use a USB charge controller in the device itself; I don't know about the T1. You are strictly on your own if you want to try a battery that is not a direct equivalent, and is not something that I would recommend trying at all with Li-Ion or Li-Poly batteries.

As far as I know the controller for the Li-Ion cells is part of the battery itself. The device only supplies the charge. The voltage of any Li-Ion battery is always the same, it comes from the chemistry of the cells. The charging voltage should be roughly the same, too.
So only the physical dimensions , the capacity and the connecting wires should matter....in therory, of course. I never would "touch" the battery itself. I solder the wires on and it either works or not.
A new Li-Ion battery with roughly the right dimensions and capacity costs around 10 EUR. I can risk that amount.
My T1 is one year out of warranty and a new original battery is way to expensive. If the home-made replacement does not work I have to by a new reader anyway.
