FAQs 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?

It is denoted Q and is given by: Q = xnF (6.12.1) (6.12.1) Q = x n F where x = number of moles of reaction, n = number of electrons transferred per mole of reaction and F = Faraday's constant
What does energy mean in a battery?
Energy or Nominal Energy (Wh (for a specific C-rate)) – The “energy capacity” of the battery, the total Watt-hours available when the battery is discharged at a certain discharge current (specified as a C-rate) from 100 percent state-of-charge to the cut-off voltage.
How do you know if a battery has a good capacity?
A battery's capacity does not tell you the amount of energy it stores or the driving range it can deliver.
