Get More Mileage From Your Laptop Computer With an External Laptop Battery
When you need to extend the operating time of your laptop computer, an external laptop battery may be your best solution. These batteries are gaining popularity in both the consumer and commercial market segments because they allow users to power their computers for longer periods of time than traditional laptop batteries.
External laptop battery generally use either the lithium-ion (Li-ion) or lithium-polymer (LiPo) battery chemistry. Both of these battery types provide high energy to weight ratios, are proven rechargeable battery technologies and are economically feasible. They are also more environmentally friendly that the older battery chemistries.
External laptop batteries are often also called universal laptop batteries because they are inherently equipped with several features to operate a wide variety of laptop computers. The key features in this regard are the variable voltage outputs and an assortment of power adapters.
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.
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.
Attention must be paid to the voltage requirements of the computer when choosing an external laptop battery. Although these batteries will often provide voltages at several discrete intervals, you must make sure that one of these available output voltages is within +/-1 volt of your laptop’s required voltage. However, since it is common to find these universal batteries provided with three to five different voltage outputs, the same battery can be used to power a number of different laptop PCs with different voltage requirements.
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.
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.
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.
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.
Consider an external laptop battery when you need a higher capacity battery to operate your unplugged laptop for an extended period of time, and get more power for your money than you would with a tradition laptop battery. Also, consider the options and special features of these extended battery packs and choose the one that best fits all of your needs.

The Power Outside – External Laptop Battery Charger – Emergency Charger
Anyone who has ever owned a laptop computer knows that it can sometimes take quite a long time for a laptop to charge the battery. One of the ways around this problem is to get your hands on an external laptop battery charger, which can really help to speed up the process, and can be used to charge a second to battery, always a good idea when you are a heavy user of the computer. This article will look at a few considerations that need to be borne in mind when buying this extremely useful laptop accessory.
The first thing to remember is that choosing a charger needs to be done with great care, since at the very least you may end up with a charger which does not charge your battery properly, or could even cause damage to the battery itself, and you could be left with no power at all for your laptop. In the least worst case you could end up with a battery that is only partially charged, which means your notebook might run out of power after just an hour or so of operation, which could cause you a lot of trouble if it happens in an opportune moment.
In the worst case scenario you could end up with a battery charger causing a lot of damage to the battery itself, which means you have to then go out and buy a completely new battery pack, which of course can be very expensive.
One of the most common mistakes is to buy a charger which is not a suitable for the type of battery itself, usually a charger that is too small to take the battery. There are some types which can charge different sizes, but these are usually only supplied by manufacturers to charge the various sizes of battery for their complete laptop range. They are not usually available for different models. It is usually better to find a universal type of charger, possibly with a docking system.
An external battery charger can be a real boon, but, as you can see, you really do need to take a lot of care when you’re choosing one because the wrong choice could leave you with practically no battery at all.
