The default battery monitor of Linux doesn't notify what is current condition of the battery juice but only when it is low. Battery Monitor comes in handy and keep you up-to-update about charging, discharging, not charging, critically low battery state of the battery. This utility is written using Python3 programming language and PyGtk3. It is available for Ubuntu and its derivatives via PPA but it can also be installed easily on any other distribution by pulling its source from github page.
You can set further warnings after notifications, it can warn you first, second and third time after the actual notification, and let you set notification stability time. These all can be changed from its preferences as well as set percentage to Low Battery and Ver Low Battery Warnings. Every time, you will start/restart your PC, it will run automatically in background. But as it’s your first time, let’s start it by yourself. Please, search for Battery Monitor launcher in your menu entries. Then simply click on it. You will get notified that Battery Monitor has started.
