Charging and Discharging Definition: Charging is the process of restoring a battery''s energy by reversing the discharge reactions, while discharging is the release of stored energy through chemical reactions. …
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 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). For example, if a battery has a capacity of 3 amp-hours and can be discharged in 1 hour, its discharge rate would be 3 amps.
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.
Batteries are seldom fully discharged, and manufacturers often use the 80 percent depth-of-discharge (DoD) formula to rate a battery. This means that only 80 percent of the available energy is delivered and 20 percent remains in reserve.
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.
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.

There is a logarithmic relationship between the depth of discharge and the life of a battery, thus the life of a battery can be significantly increased if it is not fully discharged; for example, a mobile phone battery will last 5-6 times longer if it is only discharged 80% before recharging. Special deep discharge batteries are available for applications where this might be necessary. Nickel ...

For a more accurate estimation, you can assume 80% efficiency for NiCd and NiMh batteries and 90% efficiency for LiIon/LiPo batteries. Then, the formula becomes capacity / (efficiency * chargeRate) or, to use the same values from above (assuming lithium chemistry), 100Ah / (0.9 * 10A) = 11.11 hours $endgroup$
A common way of specifying battery capacity is to provide the battery capacity as a function of the time in which it takes to fully discharge the battery (note that in practice the battery often cannot be fully discharged). The notation to specify battery capacity in this way is written as Cx, where x is the time in hours that it takes to ...
A Single Charge or Discharge method consists of a galvanostatic phase where the battery is charged (or discharged depending on the polarity of the current applied) followed by a potentiostatic phase where the current is measured versus a fixed
C-Rate of discharge is a measure of the rate at which the battery is being discharged when compared to its rated capacity. A C/2 or 0.5C rate means that this particular discharge current will discharge the battery in 2 hours. For example, a 50Ah battery will discharge at 25A for 2 hours. A similar analogy applies to the C-rate of charge.

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.
This assuming the battery is at 25°C. Formula: % Capacity = T a /T s x 100. Where. T a – Actual Test Time. T s – Rated Test Time. Battery Temperature is not as 25°C. When the battery temperature is not as 25°C, use a barely modified formula utilizing a temperature correction factor (K) from the corresponding IEEE standard.
