A laptop without a good battery is nothing more but a lesser desktop computer. Battery autonomy nowadays does not exceed 2-3 hours. And when you watch a DVD or play a game, then, you'll get a 2-hour autonomy.APM & ACPI power management systems will improve your battery using known methods: lit off the screen, shut down the hard disk, etc. Not Battery Doubler. Battery Doubler will extend your battery's autonomy even when reading a DVD with the screen's luminosity set to maximum. Battery Doubler can also accelerate battery charging when you need to quickly charge your battery somewhere (airport, friend's house, etc.), as well as recalibrate the battery when it displays a wrong remaining life. And the smart battery indicator allows you to precisely know how long your battery is going to last in hours:minutes.How can Battery Doubler improve battery autonomy? First of all, it will deactivate, shut down or put in a low power mode every single computer component when you will not use it. For example, it is useless to keep an USB port turned on no USB device is connected. It might not look like a lot of wasted power, but it really adds up, due to the number of internal circuits, I/O ports and plugged devices.When you watch a DVD movie, you don't need all the 8x speed it can provide. Battery Doubler will lower your DVD to 1x when reading a movie, saving an enormous amount of battery power. When you read a webpage or play a game, the hard disk isn't useful, but it wastes a gigantic amount of battery power you don't need. Battery Doubler knows what to shut down, disable or slow down automatically; you won't even notice it's running. All you'll notice is an incredible battery autonomy improvement!
