6 Frequently Asked Questions about “Capacity energy and power characterize the battery”
What does a battery's capacity mean?
In the simplest terms, a battery's capacity describes how many electrons it can store for later use. A battery's capacity does not tell you the amount of energy it stores or the driving range it can deliver. Even with good capacity, it's not possible to know how much energy the battery stores without knowing the voltage.
What is battery power?
Battery = Electrochemical cell or cells arranged in an electrical circuit to store and provide electrical power. Battery Power = The level of energy a battery can deliver. Battery Energy = The amount of energy stored in the battery. Examples... Memory backup, metering devices, remote sensing, and more.
