I've ordered 12 cell 7200mAh battery for my notebook HP HDX18t. When I received the battery it says 14.4V/7800mAh ( and not 7200mAh like it was stated).
1 - According to this site the number of cells in this battery is
7800mAh/2600mAh * 14.4v / 3.7v = 11.6 cells.
I installed BatteryCare program and this is what it shows
2 - According to this site the mAh of battery (converting from mWh) is
96768 / 14.4 = 6720mAh
My question is
a - Should I consider 11.6 that I got in (1) to 12 or 11 cells?
b - From (2) I didn't get neither 7800mAh nor 7200mAh but 6720. Does it means that the battery I got is not new or I should wait until I will recharge&charge it several times and after that it should increase the number in Total Capacity?
