I have a cheapy trac-fone who's charger just broke. So instead of buying a new charger for the price of a new phone, I have soldered wires to the + and - leads on the phone.
The phone uses a 3.7v 800mah litium ion battery. I suspect the battery actually charges to 4.?? volts.
I don't know the current draw of the phone so I can't be 100% sure on what to put in series with 3 AA cells to limit the voltage/current.
Any help on how to proceed is needed. I have minutes on the phone and want to keep them!
