pack is made of multiple cells connected in series and in parallel based on the voltage and current requirements of the device. HP notebooks use 3 different types of Li-Ion battery cells: cylindrical, prismatic, and polymer. The cylindrical cells are approximately 18 mm (0.7 in) in diameter by - HP nx7000 | Lithium-ion battery technology: Getting the most from Smart Batterie - Page 3
