You most likely have a little laptop battery status indicator at the top of your screen. It might show you bars, or the percentage of battery power left, or even how much longer it will run without a charge.
But that doesn't tell you about the general health of your battery. Or details like its manufacturer, chemical composition or temperature.
If these are the sort of details you'd like to know, you'll want the free BATExpert download for Windows laptops. It decodes the data about your laptop battery, giving you much more information than the little battery status icon at the top of your screen.
To download BATExpert, just click the blue button below, and on the next screen, click the blue "Download button." Scroll down a bit, and you'll find the free BATExpert download.
