So you buy a new laptop and start checking out the battery life by reading the manual that comes with it. Well wait, doesn’t every notebook manufacturer these days calm to have the longest battery life? Ofcourse their calms can be a bit farfetched. So how would you know what is the exact battery life? One common way is to use your laptop on battery to see how long it lasts, but there is now a more easier method. Imtec Battery Marker is a free tool from a Russia developer that has been designed specifically to test laptop battery. There are two modes available fast and normal with an additional option, full load or without it. Just go to Test menu and select the mode along with the full load option. View in gallery It is recommended that you perform the test with both full load and without full load. In this way you can compare how long the battery life lasts when playing games or performing CPU-heavy activity and how long it lasts when the system is idle. At the end of the test, you will get the complete report, with options to save the graph, open report folder, and send report. During my testing I got N/A result, perhaps it was because I ran it in fast mode rather than normal mode. View in gallery Fast mode normally lasts for 10 minutes while the normal mode can last upto 20 minutes or more. It will only work if your laptop is running on battery, if it is connected to A/C then the test won’t work at all. It works on Windows 2000, Windows XP, Windows Server 2003/2008, Windows Vista, and Windows 7. Enjoy!
