laptop battery charging (standalone)

[homefire]

Some Lap Top batteries look for a signal from the computer. Some go so far as to use that signal to Limit charge / discharge cycles. Set a Time Life on the dang things. I've had otherwise fine batteries refuse to charge even in the lap top. Dell did that.

It's a standard lithium ion battery pack from a samsung np270.

Hi,
I tryed to charge a laptop battery (11v, 4500mAh) with a 12v supply without succes.
I plugged in directly on the + and - (externals pins).
Maybe it lacks a signal to allow the charge ?
Does anyone tryed this with success ?

What are the other pins made for ?

Is it Lipo ?

every li-ion batt has protection board inside. so you maybe burned mosfets on it.

The battery's elements are good. The laptop says 7% and i measure 10,01v.
I don't have the charger but when i put 12v for few hours, i still have 10,01v so, it's not charging.
I thing i need a simple circuit is needed to charge with the use of the other pins but i don't know how to use them.
It's not like the ballance board i use for detectors.
I'm thinkinkg that a standalone charger would be great for using laptop battery on the detector rod.

open box and check every batt/element by tester.
