what type of battery is used in laptops
Lithium-ion battery For notebooks or laptops, lithium-ion cells are supplied as part of a battery pack with temperature sensors, voltage converter/regulator circuit, voltage tap, battery charge state monitor and the main connector. These components monitor the state of charge and current in and out of each cell, capacities of each individual cell (drastic change can lead to reverse polarities which is dangerous),[76][unreliable source?] and temperature of each cell and minimize the risk of short circuits.[77]
