How To Calculate Watt Hours Of Lithium Battery

Voltage (Volts): Capacity (Ah): Calculate Watt-Hours:

Introduction

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

Formula

The formula for calculating Watt-Hours of a lithium 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 lithium battery:

1. Enter the voltage of the lithium battery in volts in the “Voltage” input field.
2. Input the capacity of the lithium 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 lithium battery has a voltage of 3.7 volts and a capacity of 10 ampere-hours, the calculator would display “Watt-Hours: 37 Wh.”
