battery in 1 hour. For a battery with a capacity of 100 Amp-hrs, this equates to a discharge current of 100 Amps. A 5C rate for this battery would be 500 Amps, and a C/2 rate would be 50 Amps. Similarly, an E-rate describes the discharge power. A 1E rate is the discharge power to discharge the entire battery in 1 hour.
The C rating of a battery indicates its discharge rate relative to its capacity. To calculate it, use the formula: C rating=Battery capacity (Ah)/Time (hours). For example, a 10Ah battery discharged in 2 hours has a C rating of 5C. Understanding a battery''s C rating is essential for determining its performance in various applications.
Lithium Battery C-rate is a measure of the discharge rate of a battery relative to its maximum capacity. It is calculated by dividing the charge or discharge current by the rated capacity of the battery. For example, a charge current of 5,000 mA on a battery with a rated capacity of 2,500 mAh would result in a 2C rate.

Technological advances have come up with new alloys to substitute for lithium, making them a ''lithium equivalent'', therefore falling under the same rules and guidelines as lithium. The amount of lithium (or lithium equivalent) content in a battery or battery pack can be worked out as 0.3 x amp hour capacity.
Batteries 2016, 2, 17 2 of 7 discharging cycles; the greater the number of cycles the less the capacity due to a loss of active material within the cell and primarily loss of lithium inventory [15].
A deep-cycle lithium-ion battery is an electrical circuit that provides power to various essential electronics for off-grid use. These elements work together to provide a specific amount of power for various applications. To calculate the power of a battery, also known as watts, multiply the battery''s voltage (volts) by its current (amps).
To calculate the capacity of a lithium battery, you need to know its voltage and amp-hour rating. The formula for determining the energy capacity of a lithium battery is: Energy Capacity (Wh) = Voltage (V) x Amp-Hours (Ah) For example, if a lithium battery has a voltage of 11.1V and an amp-hour rating of 3,500mAh, its energy capacity would be:

A Lithium Ion battery''s published rated capacity is the capacity of the cell when the load current is one fifth of the rated capacity (the C Rate). When the current varies from C/5, the capacity will change due to chemical reaction rates including a chemical effect called concentration polarization.
Applying the formula I = Capacity x C rating, we can calculate that the continuous discharge current would be: I = 2Ah x 20C. I = 40A This means that our lithium-ion battery with a capacity of 2000mAh and a C rating of 20C is capable of delivering a continuous discharge current of up to 40 amps without experiencing adverse effects.

If the same battery were rated 0.5C, it would therefore, be considered to provide 500mA for two hours on end. On the other hand, if the same battery were, however, rated 2C, the 1000mAh cell would supply 2000mA for about 30 minutes or instead half an hour. Such capacity is typically measured using a battery analyzer.
