Almost all batteries for cars and trucks are now listed as "maintenance free," meaning that the battery is sealed, and you can't add water to it, as was required in the olden days.
But you still need to keep the top of the battery and the terminals clean. Corrosion can drain a battery quickly. Auto parts stores, and auto departments in "big-box" retailers, sell brushes made especially for cleaning battery terminals and cable ends. Many also sell a spray-on liquid that will protect the battery terminal, and discourage corrosion. A mix of baking soda and a little water will help clean terminals, and a thin coating a petroleum jelly can help prevent corrosion, too.
Make sure the battery is held down tightly, too. Over time, and a lot of rough roads, the fasteners that hold the sony laptop battery down can come loose. Bouncing around can cause the battery case to crack, which will not only cause it to fail, but it can spill battery acid.
Does iPhone iOS multitasking drain my battery life?
The official line from Apple is that iOS 4 can be trusted to properly manage background functions and minimize or eliminate fujitsu notebook battery drain. Most apps on the app switching dock are not using system resources even though they have been recently used. Some are in a suspended state and can be quickly restarted from the app switching dock.
Users have reported a different story, depending on which version of iOS they are running on what Apple device. Recent reports have included accusations that Apple doesn't police developers when it comes to their apps properly turning off background functions during sleep. The contention is that apps could increase battery drain even when the iPhone is sleeping due to programming or bugs.
There's only one way to be sure what's going on with your iPhone battery. Test the device without apps running in the background by removing apps from the multitasking dock on your iPhone. You'll get a better idea if your apps are causing a reduction in asus laptop batteries life.
