6 FAQs about [Battery capacity and battery energy]
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.
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. Even with good capacity, it’s not possible to know how much energy the battery stores without knowing the voltage. This is because a higher voltage will deliver more energy for a given capacity. The math is simple:
How do you know how much energy a battery stores?
Even with good capacity, it’s not possible to know how much energy the battery stores without knowing the voltage. This is because a higher voltage will deliver more energy for a given capacity. The math is simple: Energy (Watt-hours) = Capacity (amp-hours) x Voltage (volts)
