Battery Duration Calculator

Formula

To calculate the battery duration:

\[ BD = \frac{C}{LC} \]

Where:

\( BD \) is the battery duration in hours
\( C \) is the battery capacity in mAh
\( LC \) is the load current in mA

What is Battery Duration?

Battery duration is the time a battery can power a device before it runs out of charge. It is dependent on the battery’s capacity and the current drawn by the device. Understanding battery duration is crucial for managing the energy supply of portable electronic devices and ensuring their reliable operation.

Example Calculation

Let's assume the following values:

Battery Capacity \( C \) = 2000 mAh
Load Current \( LC \) = 500 mA

Step 1: Calculate the battery duration:

\[ BD = \frac{2000}{500} = 4 \text{ hours} \]

So, the battery duration is 4 hours.
