How to choose a Safe & Quality Dell Laptop Battery. And how to find the Laptop Battery with the longest life available for your Dell. That's need a practical way to contrast them side by side.



However, there is an important measurement of WHr(watt-hours) that determines the amount of laptop battery charging. The more WHr, the longer the battery will last between recharges. If your battery can produce one watt of power for 12 hours, then its rating is 12 WHr. Amp-Hours is another batteries' charging measurement. The difference between WHr and Amp-Hours is that the watt as a measurement of power and the Amp as a measure of current.The laptop battery provides a fixed voltage to your computer, measuring charge in watt-hours or amp-hours are equally valid methods.



For instance, if your battery lasts for 20 watt-hours and always provides 10 volts, then it is valid to state your battery's energy storage capacity as 2 amp-hours. Modern laptop batteries tend to last three to five hours, depending on the power needs of the computer and the programs the user runs. Few things are as frustrating as when your laptop battery suddenly won't charge fully or stops holding its charge for as long; when this happens, you'll probably want to buy a replacement battery such as Sony Laptop Battery. PAPATEK.COM is your ideal choice.
