There are some dangers with extracting the 18650 Lithium cells from an old laptop battery pack. You cannot just treat lithium cells like you do any other battery type.
Of any failed 6 or 9 cell laptop battery pack there is at least one cell which might be dangerous to recharge and put into use.
Check the voltages on each cell and label them once you separate them from their series parallel interconnects, and be dang careful when separating them and monitor them for heat when charging them individually.
Try and Keep the plastic of the laptop battery casing intact, as they make a great holding case for all the extra cells you will have.

My extracted cells were only rated at 1900Mah. I have some 3400mAH panasonic cells, and honestly, I grab these first as their run times are significantly longer. The extracted cells are used when the task does not require full brightness of my light for as long.
