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.
When the latter is expressed in hours, the typical unit for battery capacity is the Ampere-hour. The discharge capacity of a new battery (i.e., before the notable beginning of the battery degradation) is a function of the temperature and the discharge current profile.
The practical capacity is influenced by many factors, including the discharge rate, the cutoff voltage, the temperature, and the sample history. Finally, the term ‘state of charge’, which is closely linked to the term ‘capacity’, is defined. Angel Kirchev, in Electrochemical Energy Storage for Renewable Sources and Grid Balancing, 2015
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 that a battery can deliver in the discharge process is called the capacity of the battery. The unit of the capacity is “ampere hour” and is briefly expressed by the letters “Ah.” The label value of the battery is called rated capacity. The capacity of a battery depends on the following factors:
