Battery 1691p specifications

Hello,

I'm a student on a technical college, and I'm doing some research about li-ion battery's..
I have a question about the li-ion 1691p battery module.
Can you tell me what the voltage and amperage is that the laptop gives to the battery-pack to charge, trough the connector?
And it would be super! If you can tell what each pin is for from the connector on the battery-pack.

I really hope you can tell me,

thank you very much for all the afford,

Etiënne Harberts
