How to tell the battery power
There are many different types of batteries, and you can test all of them to see if they're charged or not. Alkaline batteries bounce when they're going bad, so drop one on a hard surface to see whether or not it bounces. Take an exact voltage reading with a multimeter, voltmeter, or battery tester to get an exact charge. Windows offers you a quick view of your battery status in the Taskbar so you can see how much percentage and how much time are left on your current charge. [pdf]
