Here is a simple script that can be used to get the Battery Status on laptop running ubuntu.

upower -i /org/freedesktop/UPower/devices/battery_BAT0

Just save the above into your /home/[user]/bin/ folder. I used BatteryStatus as the name, but any name would work. Run chmod +x BatteryStatus. And now you can just open a terminal window and type in BatteryStatus (or whatever name you gave the file) to get some details about the battery:
