I just removed the Nokia Battery used for my mobile phone; it had 4 terminals, and i measured all the voltages wrt to grnd, and i found that all the voltages were negative.
And also the battery is charged with single constant voltage like 5.7V/ something...
What are these types of battery called? What is the requirement of 3 different voltages?
How does the different voltages in battery charged?
This is what in Nokia? when i look into Panasonic mobile, it had numerous pins in its adapter output, but the battery had only 2 terminals? Why is it like that?
