# Battery widget
Simple and easy-to-install widget for Awesome Window Manager.

This widget consists of 

 - an icon which shows the battery level: ![Battery Widget](./bat-wid-1.png)
 - a pop-up window, which shows up when you hover over an icon: ![Battery Widget](./bat-wid-2.png)
 - a pop-up warning message which appears on bottom right corner when battery level is less that 15%: ![Battery Widget](./bat-wid-3.png)
