# Battery
The **battery** widget can be used to display the battery level of a device, typically as a **percentage**, **Volts**, or **mVolts**. By monitoring the battery level, you can better understand how long you can continue to use the device before needing to replace or recharge the batteries.
In the **Widget options** modal box, enter a **name** as the label for your widget in the **Name** text box, and select the **data field** bound with the battery voltage from the **Data field** drop-down list.
To add a **color** to the **background** of the widget, click on the **Background color** box and choose a color from the **color picker**.
Click on the **Save** button.
The resulting **Battery** widget looks something like this:
