Above mentioned methods are teaching you how to buy a replacement battery for you notebook. Buy the following ways to tell you how to buy external batteries. These external batteries can be very useful, doubling the lifespan of your laptop. Here are some ways to ensure you've always got a charge.
1. Replacement of Internal Batteries. Most laptops come with replaceable internal batteries (a major exception: recent MacBook Pro models, which build their batteries permanently inside the case). In such cases, doubling the lifespan of your battery is as simple as buying a second one--when the power runs out, just swap the two. Your primary decision in this case is whether to buy OEM battery or to buy a third-party replacement designed to work with your laptop. Third-party batteries compete with branded models by being cheaper or providing more power than the branded model. The best way to judge the power of these batteries is to compare their amperage. However, these batteries are cheaper, but the quality may be not high, so you should make detailed research about them.
2. External Batteries. A second method is to hook up an external battery pack; typically, these are sized to match your entire laptop and are attached to its bottom. External batteries come in two models. It will either provide a standard power input cable to your laptop -- that is, you connect the battery to the laptop when needed, and it thinks it's drawing from wired power -- or it provides a regular wall jack into which you'd plug your charger. But they can be an excellent choice for people who routinely spend more than a day or two on the road without a regular chance to recharge.
3. Finally, consider alternate methods of keeping your battery charged. Experienced road warriors get into the habit of looking for power outlets wherever they go -- coffee shops, hotel rooms, airport waiting areas -- and grabbing an extra 10 minutes of juice wherever they can. A complement of external cables, allowing a charge off a car or airline power jack, may solve your power issues more effectively than a second battery, with the advantages of lower cost and much lower weight in your carry-on.
