Test your notebook's battery

Do you know how long the battery of your notebook lasts when you are running different tasks on your device?

You probably know that the manufacturer of the notebook claims that it will last for a certain amount of time, but those figures often don't translate well to regular use scenarios.

Or maybe you have been burned before, and know that manufacturers often "cheat" when it comes to these times, for instance by dimming the screen before running tests.

Battery Eater Pro is a freeware utility that tests the battery of a notebook in certain modes, and displays accurate information about battery life in a report at the end of the test.

Just download and unzip Battery Eater Pro to your hard drive and run it once that is done. A great thing about the software is that it does not need installation, so no tampering with your system at all.

Once you start Battery Eater Pro it will wait until the battery is fully loaded. Once this is done you can start the test with the shortcut SHIFT + F3. (disconnect the power plug before you do that)

The test will run until the notebook runs out of power and powers off. Connect the notebook to a power source and Battery Eater Pro will load automatically at startup and display the results of the battery test. The test results will show accurate information which may - and usually do - differ from the numbers of the manufacturer.

Newer versions of the program allow you change some preferences before running the test. This includes selecting a different benchmark mode, whether you'd like a battery charging graph to be created, or the width of the graph and the OpenGL resolution. Here it is also possible to to change the interface language of the program.

Closing Words

Battery Eater Pro is a free program to test the battery of a mobile device running Windows. You may use it to get a more accurate reading on the battery power of the device, and may use the resulting data to find out if the claims of the manufacturer of the device in regards to battery life are true.

Battery Eater Pro has not been updated since 2010, which seems to indicate that the developers have put the program on ice, or stopped development completely. It is still available however, and should run on most versions of the Windows operating system.
