But if there is any lesson here it is to avoid non-maker batteries. I will not write again why.
I want to have a long play time out of doors. So I decide to buy a high capacity battery for my Apple Macbook Pro from http://www.brilliantstore.com/apple_laptop_batteries_dekcell_bl_5872_replacement.html. But my original battery is 3 cells and the voltage is 11.1V. Can I use 9 Cells battery to replace the 3 cells original battery.
