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 energy stored in a battery, called the battery capacity, is measured in either watt-hours (Wh), kilowatt-hours (kWh), or ampere-hours (Ahr). The most common measure of battery capacity is Ah, defined as the number of hours for which a battery can provide a current equal to the discharge rate at the nominal voltage of the battery.
The term "capacity," which is used to refer to a battery's ability to hold and distribute electrical charge, is indicated by the letter "C". It is a key variable that determines how much power a battery can deliver. The ampere-hour (Ah), which measures how much electric current a battery can produce for an hour, is the common unit of capacity.
Battery capacity indicates how much energy a battery can store, while voltage determines the power output. Together, these factors influence the performance and longevity of batteries in various applications. What are watt-hours (Wh), and how do they relate to battery performance? What is battery capacity, and why is it important?
Capacity: The entire energy in a battery is measured here, and it is usually expressed in ampere-hours (Ah). It provides information on how much charge the battery can deliver at a particular discharge rate. Energy Density and Power Density: The quantity of energy stored per unit of mass or volume is measured by the energy density (Wh/kg or Wh/L).
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.
