Before, your only solution to have a decent battery life for your laptop was to buy an extra one. Now, there's a lighter, more efficient, and cheaper alternative: Battery Doubler! Because it doesn't use standard techniques (dim screen light, etc.), but finds out what is not being used and turns it off, such as, for example, the USB ports, you can achieve double the activity without sacrificing comfort.
After using your battery a lot without paying attention to discharge and recharge it fully every time, its performance becomes very low. With Battery Doubler, simply run the recalibration wizard and it does the entire job for you - automatically!
From the configuration window to the battery status indicator features, Battery Doubler excels in ease-of-use. The interface fully respects Microsoft's guidelines and is very intuitive. Because you don't always want to read a 300-pages manual before using a software, you will understand how to use Battery Doubler in no time.
