I have a Motorola Startac Li-Ion battery pack for my cell phone (no vibrator). I'd like to recondition and charge it on my Maha charger but I'm not sure which terminals to charge at. There are 4 terminals on the battery pack. Here are some voltage and resistance measurement's I took.
+ = positive probe of multi-meter
- = negative probe of multi-meter
Terminal
1 2 3 4| Volts | Resistance
--------|--------|--------------
+ - . . | 0.00V | infinite
- + . . | 0.00V | infinite
+ . - . |-3.56V | infinite
- . + . | 3.56V | infinite
+ . . - | 0.00V | infinite
- . . + | 0.00V | infinite
. + - . |-4.06V | -38.0 k-ohm
. - + . | 4.06V | infinite
. + - . | 0.00V | 12.5 k-ohm
. - + . | 0.00V | 12.5 k-ohm
. . + - | 4.00V | infinite
. . - + | 4.00V | -3.25 k-ohm
Questions:
1) what is the normal voltage of a single Li-ion cell?
2) can someone diagram what the internals of this battery pack looks like? complete with diodes, resistors or any other devices?
thanks for any help
