I need to get another laptop battery so I can run my laptop for more than two hours at a time. I read some information, and it seems like the best option is to get an external laptop battery. Where's the best place to get one and do they come with adapters to connect to my laptop?

However, this really is a higher tech battery and offers some features like a 5V USB port, automatic voltage selection and even the ability to charge from a solar panel.

My laptop battery only runs my computer for five or ten minutes now. It's an older Gateway laptop and I can't find a replacement laptop battery for it anywhere. I'm going to get an external laptop battery for it, but I don't know what to look for. Your help is appreciated!

This is especially true for the professional that logs his or her hours 'in the field'. An external laptop battery 'system' will include the battery pack itself, a charger for it and a cable and plug to fit your laptop's power input terminal. Most external battery packs can be used with a variety of notebook PCs (providing that the electrical specifications are met) and therefore are supplied with an assortment of adapters to accomodate a range of power input terminals.

Purchasing an external laptop battery requires careful selection to ensure the safe operation of your computer due to the wide ranging electrical requirements found in laptops, notebooks and tablet PCs. Critical consideration must be given to the voltage (V) and amperage (A) ratings of the computer when selecting an external battery. Another specification to consider in the purchase of an external battery is the watt-hours (W-Hr) since a higher W-Hr rating will power the computer for a longer period of time than one with a lower rating. However, while the voltage and amperage selection is critical in the selection process, the watt-hour rating is generally more of a convenience criteria.

You may be able to find the laptop manufacturer's electrical specs for your computer from their web site or in your user's manual, but the easiest and most readily way to obtain that is to examine the charger that came with your notebook. You should easily be able to read the label on the OEM charger and find the voltage and amperage specs on it. Many, if not most, external batteries have voltage outputs that are switch selectable for two or more voltages. You will need to select an external battery that has a voltage output that matches your laptop's voltage requirement. Voltage specs of +/-1 will generally also work with your computer system, but you should check with the battery supplier if you need more information. You will also need to give careful consideration to the amperage spec of both your laptop and the external lapop battery. The external battery will need to be rated higher than the laptop's spec for amps or it won't be able to supply enough current to power the computer.

While the selection of external laptop batteries is a relatively straight-forward process in regard to the consideration of the electrical specifications, the connection of the external battery to the computer via its' power terminal can be a little more problematic. The power output cable (the cable from the external battery to the laptop PC) will generally terminate with a plug at the end of it. Coaxial style (barrel style) adapters are placed over this plug so that the there is a proper physical fit and polarity match with the laptop. External laptop batteries are often supplied with a package of tips to accomodate a variety of computers. Check with the battery supplier to make sure that an adapter tip will be supplied to fit your computer.
