BU-105: Battery Definitions and what they mean

Batteries are specified by three main characteristics: chemistry, voltage and specific energy (capacity). A starter battery also provides cold cranking amps (CCA), which relates to the ability to provide high current at cold temperatures. The most common battery chemistries are lead, nickel and lithium, and each system needs a designated charger.

Battery rated energy vs. capacity

An amp hour (Ah) is a measure of charge and provides an estimate of how much energy a battery can hold. It is the amount of energy charge in a battery that will allow one ampere of current to flow for one hour. A watt hour (Wh), on the other hand, is a measure of power and indicates the equivalent to one Watt of average power flow over an hour.

6 FAQs about [The difference between battery capacity and power]

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 the difference between current and power output of a battery?

Current is expressed in Amps (A). It quantifies how many electrons are flowing per second. The capacity of a battery defines how much total energy is stored in each battery. The power output of a battery is how much energy a battery can give at a given time. This is a very important factor as it defines what you should use the battery for.

How do you calculate power capacity of a battery?

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.

How does battery capacity affect battery performance?

Battery capacity indicates how much energy a battery can store, while voltage determines the power output. Together, these factors influence the performance and longevity of batteries in various applications. What are watt-hours (Wh), and how do they relate to battery performance? What is battery capacity, and why is it important?

How is power capacity measured in a 2Ah battery?

The way the power capability is measured is in C 's. A C is the Amp-hour capacity divided by 1 hour. So the C of a 2Ah battery is 2A. The amount of current a battery 'likes' to have drawn from it is measured in C. The higher the C the more current you can draw from the battery without exhausting it prematurely.

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.
