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.
Battery capacity is often measured in Amp-hours (Ah), which indicates how much current a battery can deliver over a specific period. Voltage, on the other hand, represents the electrical potential difference that drives current through a circuit. Together, these two metrics are crucial for evaluating battery performance in various applications.
Understanding Voltage Voltage is the measure of electrical potential difference between two points in a circuit. It influences how much current flows from the battery to the load. Higher voltage batteries can deliver more power to devices, which is essential for applications requiring high energy output.
Wh is calculated by multiplying the number of Amps with the battery voltage. For example, a 12V100 (a 12 volt battery with a capacity of 100Ah) has a capacity of 12 x 100 = 1200Wh. A 24V50Ah battery has a capacity of 24 x 50 = 1200Wh. So these batteries have the same capacity, only one works on 12 volts and the other on 24 volts.
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.
To measure a battery's capacity, use the following methods: Measure the time T it takes to discharge the battery to a certain voltage. Calculate the capacity in amp-hours: Q = I×T. Or: Calculate the capacity in watt-hours: Q = P×T. What is the C rating of a battery? The C rating determines the rate at which the battery discharges.
How To Calculate Battery Capacity?
The basic formula for calculating the capacity of a battery is to multiply the voltage by the current and then by the time. The formula is as follows: Capacity = Voltage × Current × Time Where: Capacity is the battery''s capacity in ampere-hours (Ah). Voltage is the battery''s voltage in volts (V).

Battery Capacity: Overview and Guide to Understanding
A battery''s energy capacity can be calculated by multiplying its voltage (V) by its nominal capacity (Ah) and the result will be in Wh/kWh. If you have a 100Ah 12V battery, then the Wh it has can be calculated as 100Ah x 12V = 1200Wh or 1.2kWh. Note that Watt-hours (Wh) = energy capacity, while ampere-hours (Ah) = charge capacity.
