A battery’s capacity can be estimated relatively accurately using a set of measurements and some complex math, but the most simple way to measure a battery’s capacity is to measure the power going into or out of the cell. Power going into the cell would be charge testing and power coming out of the cell.

Customer ServiceC-rates are commonly used to describe battery power. For example, a 1C discharge rate describes the current at which the battery will discharge in 1 hour, while a battery with a 5C discharge rate, being 5 times faster, will discharge in 12 minutes (60 minutes divided by 5). The higher the C-rate, the more of a punch the battery can deliver.
Customer ServiceCapacity is the leading health indicator of a battery, but estimating it on the fly is complex. The traditional charge/discharge/charge cycle is still the most dependable method to measure battery capacity.

To test the capacity of a battery cell, you have to fully charge and fully discharge the cell while precisely measuring the energy in at least one direction.
Power capacity is how much energy is stored in the battery. This power is often expressed in Watt-hours (the symbol Wh). A Watt-hour is the voltage (V) that the battery provides multiplied by how much current (Amps) the battery can provide for some amount of time (generally in hours). Voltage * Amps * hours = Wh.
The battery energy calculator allows you to calculate the battery energy of a single cell or a battery pack. You need to enter the battery cell capacity, voltage, number of cells and choose the desired unit of measurement. The default unit of measurement for energy is Joule.
To test the capacity of a battery cell, you have to fully charge and fully discharge the cell while precisely measuring the energy in at least one direction. Also, being able to test a battery’s true capacity gives you leverage when buying battery cells.
The way the power capability is measured is in C 's. A C is the Amp-hour capacity divided by 1 hour. So the C of a 2Ah battery is 2A. The amount of current a battery 'likes' to have drawn from it is measured in C. The higher the C the more current you can draw from the battery without exhausting it prematurely.
