Does anyone know the battery pinout for Samsung SCH-U740 battery?
My wife picked up a used phone, Samsung Alias SCH-U740, for my 13 year-old son. It didn't have a battery so she bought a used battery and a charger.
The battery doesn't seem to charge and the phone won't power on. After being plugged in for about an hour, I checked the voltage on the battery with a multimeter. I can't get any voltage on any of the pins.
I'm trying to find the battery pinout so I can connect a power supply to test the phone.
There are 3 pins on the battery / phone. The battery shows a + sign next to one pin and a - next to the other side but what is the middle pin for?
