The charge/discharge rate is calculated as the charge/discharge current divided by the rated capacity of the battery. For example, with a battery rated at 200Ah, discharging at 100A would deplete its entire capacity in 2 hours, resulting in a discharge rate of 0.5C. in simple terms, is the ratio of its actual performance parameters to its
battery chemistries have different rated voltages; for example, Li-ion cells have a rated voltage of 3.7V, while alkaline cells have a rated voltage of about 1.5V. Higher voltages result in higher capacity and output power. • Capacity: A battery''s capacity refers to the amount of electrical energy that it can store and deliver.
