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.
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
The higher the current, the more work it can do at the same voltage. Power = voltage x current. 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.
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.
The ‘theoretical capacity’ of a battery is often calculated using Faraday's law of electrolysis; but the ‘practical capacity’ is always less. The practical capacity is influenced by many factors, including the discharge rate, the cutoff voltage, the temperature, and the sample history.
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.

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. Since voltage is pretty much ...
In Fig. 5 b, we calculate the correlation between the battery capacity and the relaxation voltage at different cut-off times.

What is battery capacity, and why is it important? How do milliampere-hours (mAh) measure battery capacity? What are watt-hours (Wh), and how do they relate to battery performance? How does voltage affect battery capacity and performance? Why is the relationship between mAh, Wh, and voltage critical for understanding batteries?
Parallel connections provide an increased current capacity, making them suitable for applications that require higher currents. However, one disadvantage of parallel connections is that the overall voltage remains the same, which may …
The relationship between voltage and SoC is not linear. This means that a slight change in voltage can represent a significant change in SoC at specific points of the discharge curve. For instance, a battery''s voltage may remain relatively stable between 40% and 80% charged, but it can drop sharply as it approaches 20% or below. This characteristic is crucial …
Often referred to as the Ohm''s law equation, this equation is a powerful predictor of the relationship between ... The greater the battery voltage (i.e., electric potential difference), the greater the current. And the greater the resistance, the less the current. Charge flows at the greatest rates when the battery voltage is increased and the resistance is decreased. In fact, a …
