Battery capacity is a critical metric that defines the amount of energy a battery can store and deliver, usually expressed in ampere-hours (Ah) or watt-hours (Wh). This measurement plays a vital role in determining how long a device can operate before needing a recharge.
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 higher the power, the quicker the rate at which a battery can do work—this relationship shows how voltage and current are both important for working out what a battery is suitable for. Capacity = the power of the battery as a function of time, which is used to describe the length of time a battery will be able to power a device.
In essence, the larger the capacity, the longer the battery can power a device, making it particularly important for applications where long usage times are crucial, such as in electric vehicles, smartphones, and renewable energy systems.
Battery capacity is conventionally measured using units such as ampere-hours (Ah), watt hours (Wh), or kilowatt hours (kWh), depending on the technology used. When it comes to the usage of battery, it can be described as the total power it holds, which, in turn, determines how long it can run without recharging.
Capacity = the power of the battery as a function of time, which is used to describe the length of time a battery will be able to power a device. A high-capacity battery will be able to keep going for a longer period before going flat/running out of current.
