Where are the batteries on a laptop battery?

Coming to the pinout of my laptop battery connector, the lithium-ion cells are arranged in ‘3 series 2 parallel’ configuration (3S2P), and the blades at both ends of the 9-blade/pin battery connector are ‘power’ terminals (Pin 9 and 8: Negative/Pins 2 and 1: Positive). The SMB is on pins 6 and 7.
