BatteryCare

One of the things that annoy people the most is when their laptop's battery suddenly says that it's low on power despite the fact that we barely used it at all and worse, there isn't a place where we can recharge it.

BatteryCare is the best program out there for those whose laptop's battery's performance seems to  decrease overtime since it's not only a excellent program, but also comes with a detailed website and written guide that helps configure your battery even without the program's help making it very useful for beginner's that don't know much about energy saving in laptop's.

After a quick and stress-free installation process, the application places an icon in the system tray; right-clicking allows you to instantly change the power plan you currently use, to others such as Balanced, High Performance, or Power Saver.

Hovering over the icon also allows us to consult things like the battery's charge level, CPU temperatures and general settings where we can alter the configurations of the program as well as those from the PC.
  
Finally, if you double click, you can access a more detailed display that includes battery status, discharge cycles and other details like tension and such.

This program may suffer from occasional glitches but with each update, they're solved one by one so if your laptop's battery is lasting less and less everyday, you should try this handy tool and while you're at it, you should try the guide as it can really help you with whatever problems your battery might have overtime.
