The time, usually measured in hours (h) or fractions of an hour, is the charge or discharge cycle duration. The formula to calculate the lithium-ion battery capacity is: Capacity (Ah) = Current (A) x Time (h) If you have a lithium-ion battery that can provide a current of 2 A for 3 hours, you can calculate its capacity as: Capacity (Ah) = 2 A x 3 h = 6 Ah
