Dell Laptop Batteries

Dell laptop batteries come in various watt hours. If you choose a higher watt hour rating, you will have more cord-free time on your laptop before you need to charge it again. There is no standard time for everyone using a laptop on battery power, since the length of the charge will depend on what applications you are running and how many you are running at the same time. Also, the brightness of your display can greatly affect battery power usage.

You can fully charge your laptop battery in a couple of hours, even if it was absolutely out of charge. However, depending on the type of use you put your laptop through, the battery will likely run down in about two years. Some users prefer to buy a new battery before it runs down, so they have more cordless time.

Not all batteries are created equal. Some are produced in Asia with inferior components, and don't have any of the safety or use guarantees of a brand-name battery. As such, savvy buyers are unlikely to choose batteries on price alone.

Dell laptop batteries often have LED lights that tell you how much charge is left in the battery. If you depress a button, the lights will light up or stay dark according to the percentage of charge left. Also, if you use your DVD option when you are unplugged, there is an additional optical battery you can buy to extend the charge of your master battery.
