Cell phone battery
My friend gave me an old cell phone, with no battery. (No it does not have service). I don't know if it even works. It is a Motorola i860. Where the battery goes are four pins. How can I connect a AA, or AAA, etc battery to it to see if it works. The first time I tried it, it got real hot and then the battery smelled like it was burning. The second time it sparked. Is it even possible to do this? If it is, I need to know the voltage, polarity, and what pins to use.
