Things to remember before order Dell Latitude D620 laptop battery

March 24, 2010 - PRLog -- Every laptop battery is given a power rating in order to show you, the consumer, about how long your Dell Latitude D620 battery should last before it needs to be recharged. These electrical specifications are given using volts (V) and milliAmps (mAh). For example, you may see your Dell Latitude D620 battery is given a rating of: 11.1V, 4400mAh.

Volts and milliAmp hours are used because they measure the amount of energy used by a Dell Latitude D620 battery. A volt (V) is a measurement used for the amount of pressure the positive and negative electrodes produce in a laptop battery during the process of discharging energy. Amps (A) measure the amount of resistance the energy in your Dell Latitude D620 battery produces in order to power a laptop.

You may also notice that increasing the size of the pipe and shower head without having to open the faucet all the way will produce similar results.This is an example of the amount of resistance in the flow of energy. Measuring this resistance is measured in terms of amps. In terms of a Dell Latitude D620 battery, the amount of resistance is dependant on the size of the Dell laptop battery and the amount of energy inside.

Keep in mind that technology constantly changes. Your old Dell Latitude D620 laptop battery(http://www.aussie-battery.com/batteries.php/Dell+Latitude...) may be rated at a lower run time than a newer one because of technological advancements that have produced longer lasting laptop batteries.
