How To Calculate Watt Hours Of A Battery

Introduction

Estimating the energy capacity of a battery is essential for various applications, from electronics to renewable energy systems. Our Watt-Hour calculator simplifies this process by calculating the Watt-Hours of a battery based on its voltage and capacity.

Formula

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

Watt-Hours=Voltage (Volts)×Capacity (Ah)Watt-Hours=Voltage (Volts)×Capacity (Ah)

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 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: 600 Wh.”
