Discharge Rate (C-rate) The discharge rate, expressed in C-rates, is a crucial factor affecting battery performance. Higher discharge rates lead to increased internal resistance, resulting in more significant voltage drops. For instance, discharging at a rate of 2C can considerably reduce the battery''s capacity compared to lower rates. This
C-rate is a measure of the rate at which a battery is charged or discharged relative to its capacity. It is the charge or discharge current in Amps divided by the cell capacity in Ampere-hours. A 1C rate means that the discharge current will discharge the entire battery in 1 hour.
This article contains online calculators that can work out the discharge times for a specified discharge current using battery capacity, the capacity rating (i.e. 20-hour rating, 100-hour
For smaller batteries, you can measure the current during charging or discharging using a multimeter. By dividing the measured current (in amps) by the battery''s capacity (in ampere-hours), you can calculate the C-rate. For example, if a 2,000mAh battery is charging at 1,000mA: C-rate = 1,000mA ÷ 2,000mAh = 0.5C. Part 4. How does the charging
discharge current. The battery capacity also greatly depends on the discharge current. For example, compare a 20 hour and a 1 hour rate: For 20 hours, 0.05C (A) x 20 (h) = 1C (Ah) For 1 hour, 0.6C (A) x 1 (h) = 0.6C (Ah) This means that the capacity for the one hour rate is 60% less of the 20 hour rate. Evidently, increasing discharge current
Understanding C-rate in Lithium Batteries. When dealing with lithium batteries, the C-rate is a crucial factor that dictates how fast a battery charges or discharges relative to its capacity.If a battery with 1000mAh capacity takes one hour to charge or discharge completely, its C-rate is 1C; if it takes two hours, it''s 0.5C.
The charging/discharge rate may be specified directly by giving the current - for example, a battery may be charged/discharged at 10 A. However, it is more common to specify the charging/discharging rate by determining the amount of time it takes to fully discharge the battery. In this case, the discharge rate is given by the battery capacity
The battery discharge rate is the amount of current that a battery can provide in a given time. It is usually expressed in amperes (A) or milliamperes (mA). The higher the discharge rate, the more power the battery can provide. To calculate the battery discharge rate, you need to know the capacity of the battery and the voltage. The capacity is
The discharge characteristics of lithium-ion batteries are influenced by multiple factors, including chemistry, temperature, discharge rate, and internal resistance. Monitoring these characteristics is vital for efficient battery management and maximizing lifespan. By analyzing discharge curves and understanding how different conditions affect
C-rate is a measure of the rate at which a battery is charged or discharged relative to its capacity. It is the charge or discharge current in Amps divided by the cell capacity in Ampere-hours. A 1C rate means that the discharge current will
This article contains online calculators that can work out the discharge times for a specified discharge current using battery capacity, the capacity rating (i.e. 20-hour rating, 100-hour rating etc) and Peukert''s exponent.
It is defined as the discharge current divided by the theoretical current draw under which the battery would deliver its nominal rated capacity in one hour.[29] A 1C discharge rate would deliver the battery''s rated capacity in
The battery capacity also greatly depends on the discharge current. For example, compare a 20 hour and a 1 hour rate: For 20 hours, 0.05C (A) x 20 (h) = 1C (Ah) For 1 hour, 0.6C (A) x 1 (h) = 0.6C (Ah) This means that the capacity for the one hour rate is 60% less of the 20 hour rate. Evidently, increasing discharge current causes a decrease in
Discharge time is basically the Ah or mAh rating divided by the current. So for a 2200mAh battery with a load that draws 300mA you have: $frac{2.2}{0.3} = 7.3 hours$ * The charge time depends on the battery chemistry and the charge current. For NiMh, for example, this would typically be 10% of the Ah rating for 10 hours.
discharge current. The battery capacity also greatly depends on the discharge current. For example, compare a 20 hour and a 1 hour rate: For 20 hours, 0.05C (A) x 20 (h) = 1C (Ah) For
The discharge current of the battery: the larger the current, the output capacity decreases; b. Discharge temperature of the battery: when the temperature decreases, the output capacity decreases; c. The discharge cut-off voltage of the battery: the discharge time set by the electrode material and the limit of the electrode reaction itself is generally 3.0V or 2.75V. d.

The battery discharge rate is the amount of current that a battery can provide in a given time. It is usually expressed in amperes (A) or milliamperes (mA). The higher the discharge rate, the more power the battery
The battery cycle life for a rechargeable battery is defined as the number of charge/recharge cycles a secondary battery can perform before its capacity falls to 80% of what it originally was. This is typically between 500 and 1200 cycles. The battery shelf life is the time a battery can be stored inactive before its capacity falls to 80%. The
Discharge time is basically the Ah or mAh rating divided by the current. So for a 2200mAh battery with a load that draws 300mA you have: $frac{2.2}{0.3} = 7.3 hours$ * The charge time depends on the battery
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
Using a battery discharge calculator can give you a deeper understanding of how different battery materials affect discharge rate. Carbon-zinc, alkaline and lead acid batteries generally decrease in efficiency when they discharge too quickly. Calculating discharge rate lets you quantify this.
The discharge curves for a Li-ion battery below show that the effective capacity is reduced if the cell is discharged at very high rates (or conversely increased with low discharge rates). This is called the capacity

The lithium battery discharge curve is a curve in which the capacity of a lithium battery changes with the change of the discharge current at different discharge rates. Specifically, its discharge curve shows a gradually
In electricity, the discharge rate is usually expressed in the following 2 ways. (1) Time rate: It is the discharge rate expressed in terms of discharge time, i.e. the time experienced by a certain current discharge to the specified termination voltage ch as C/5, C/10, C/20 (2) C rate: the ratio of the battery discharge current relative to the rated capacity, that is, times the rate.
The discharge curves for a Li-ion battery below show that the effective capacity is reduced if the cell is discharged at very high rates (or conversely increased with low discharge rates). This is called the capacity offset, and the effect is common to most cell chemistries.
The battery discharge rate is the amount of current that a battery can provide in a given time. It is usually expressed in amperes (A) or milliamperes (mA). The higher the discharge rate, the more power the battery can provide. To calculate the battery discharge rate, you need to know the capacity of the battery and the voltage.
From the above equation, the variation of discharge time is dependent on the discharge current. The battery capacity also greatly depends on the discharge current. This means that the capacity for the one hour rate is 60% less of the 20 hour rate. Evidently, increasing discharge current causes a decrease in the apparent Ah capacity.
This is known as the "hour" rate, for example 100Ahrs at 10 hours. If not specified, manufacturers commonly rate batteries at the 20-hour discharge rate or 0.05C. 0.05C is the so-called C-rate, used to measure charge and discharge current. A discharge of 1C draws a current equal to the rated capacity.
However, it is more common to specify the charging/discharging rate by determining the amount of time it takes to fully discharge the battery. In this case, the discharge rate is given by the battery capacity (in Ah) divided by the number of hours it takes to charge/discharge the battery.
The most common unit of measurement for discharge rate is the amp (A). The faster a battery can discharge, the higher its discharge rate. To calculate a battery’s discharge rate, simply divide the battery’s capacity (measured in amp-hours) by its discharge time (measured in hours).
Maximum Continuous Discharge Current – The maximum current at which the battery can be discharged continuously. This limit is usually defined by the battery manufacturer in order to prevent excessive discharge rates that would damage the battery or reduce its capacity.
