How To Calculate Watt-Hours Of A Battery

Introduction

Estimating the Watt-Hours of a battery is crucial for understanding its energy storage capacity. Our online calculator simplifies this calculation based on the battery’s voltage and capacity.

Formula

The formula for calculating Watt-Hours of a battery is given by:

Watt-Hours=Voltage×CapacityWatt-Hours=Voltage×Capacity

How to Use

Follow these simple steps to calculate the Watt-Hours of a battery:

  1. Enter the voltage of the battery in volts in the “Voltage” input field.
  2. Input the capacity of the battery in ampere-hours (Ah) in the “Capacity” input field.
  3. Click the “Calculate” button to obtain the Watt-Hours.
  4. The result will display the calculated Watt-Hours of the battery with precision.

Example

For example, if a battery has a voltage of 12 volts and a capacity of 50 ampere-hours, the calculator would display “Watt-Hours of Battery: 600 Wh.”
