Popular consumer versions of these extended laptop battery packs are commonly supplied in the 74-142 WHr rating range. This will generally supply enough power to operate a laptop computer for an additional 5 to 12 hours, depending on the battery’s capacity and the power requirements of the computer. These consumer targeted batteries will generally weigh from one and a half to three pounds. Commercial versions of these batteries are typically available in the 200-500 WHr range to maximize your computer’s operating time when using them as the remote power source for the laptop.

Although not so much a safety concern, it is also important to make sure that the amperage of the battery pack is equal to or exceeds the amperage requirements of the laptop computer or it will not be able to deliver power to the laptop. This specification is most easily found by looking at the label on the charger that came with the OEM battery and laptop computer.

Most times these external batteries will be able to recharge your laptop computer’s internal battery. However, this is dependent on the computer’s circuitry and may not always be the case. Some of these batteries and their associated chargers offer an automatic voltage detection of the laptop computer and provide an LED power display to indicate the charge level of the external battery. A few of these batteries require the use of the PC’s power adapter to energize the battery, but most are equipped with their own battery charger. Also, some chargers will operate at both 120 and 240 volts making them convenient for international travel and usage. Optional converters are also available to charge these batteries from a 12 volt DC power source, such as a car battery.Dell Latitude e6400 Battery Dell Latitude e6400 Battery Dell Latitude e6400 Battery Dell Latitude e6500 Battery

A distinct benefit that many external batteries offer is their ability to power other devices, such as: PDAs , iPods, digital cameras, portable DVD players and cell phones. USB power cords are supplied with many external batteries that have a 5 volt output to facilitate this.

In addition to the voltage requirement, it is necessary to ensure that a power adapter that fits your computer’s power port is either included with the battery itself or is available as an option. The chargers that are equipped with these batteries terminate in a plug over which an adapter needs to be placed. In many cases these are called barrel style adapters since they slide over a mini-microphone type plug on the charger’s side and have a cylindrical shape.

The key optional specification in the choice of an extended battery pack is the amount of energy that it will hold, since it is this stored charge that will provide power to operate the laptop computer. Although many laptop batteries are specified with the milliamp-amp hour (MAh) rating of the battery to indicate the battery’s storage capacity, the watt-hour (WHr) rating is a better specification because it is more of an absolute value that is independent of the battery’s voltage.Dell Latitude e6500 Battery Dell Latitude e6500 Battery
