Hello, 

I need to use this battery for another project( audio amplifier). I don t have the laptop. I manage it to unblock the output by adding the ground to the 4 th pin starting from the ground pin. But it is possible to charge it? And how?

This Dell battery requires some special commands to activate charging then apply voltage and current according to some SBS parameters.

not the best choice for this sort of application. Dell batteries could not be charged directly from Lab PSU. You will need at least additional Arduino pcb with "Dell Charge" sketch.

Me recommend you to find any Asus, Acer, HP, Lenovo, MSI battery to play with.

They are easy to charge with external current limited power supply.

This is typical "T54FJ line" battery with classic Dell pinout, nothing exotic.
