Laptop Battery Power Monitor

Laptop Battery Power Monitor is a simple-to-use program that enables you to monitor the lifespan of your notebook battery. It doesn't integrate complex settings and can be handled by all types of users, regardless of their skill level.
The interface is based on a very small frame that resembles a cylinder showing the battery's current capacity, along with the percent.
It stays on top of other windows and can be moved to any position on the screen, which comes in handy when you're working in multiple applications, since you can immediately get a glimpse of the battery level.
When hovering the mouse cursor over this small frame, you can view additional battery information, namely the charge status, remaining hours and remaining battery life.
By opening the right-click menu you can decrease the battery monitor size and adjust the transparency level. There are no other options provided by this tool.
Laptop Battery Power Monitor has a minimal impact on the system resources, using a low amount of CPU and RAM. It has a good response time and works well, without causing the operating system to hang, crash or pop up error dialogs.
Unfortunately, Laptop Battery Power Monitor has not been updated for a very long time, and some important features are missing (e.g. visual alerts and sound notifications for user-defined critical levels).
