With the availability and versatility of modern gadgets, it is easy to take them for granted until the batteries go dead. Scrambling to http://www.adapterlist.com/dell/vostro-1500.htm find an electrical outlet in the middle of a crowded airport or a local coffee shop is all it takes to remind laptop users of the importance of a good battery. Having a backup for these occasions is even better. Whether replacing a worn-out battery or buying an extra one for an emergency, knowing what to look for makes the process easier and less likely to go awry.

When looking to buy a long battery life laptop, it is best to stick with reputable brands and to look for a warranty of at least twelve months. Depending on the power used by the computer and the programs being run, newer versions of laptop batteries last approximately three to five hours. Eventually, however, the battery starts to lose its charge more quickly or to stop fully charging. The first thing to consider when buying a replacement is the model number and make of the laptop. This can be found either in the user’s manual, on the original box, on the inside of the battery compartment, or on the outer covering of the battery itself.

There are usually several choices of batteries for any particular model and make of laptop. Although there are different kinds of batteries, a specific type is usually required for a particular computer. In addition to choosing the correct kind of battery, it is preferable to buy one that holds a charge http://www.adapterlist.com/acer/as07b41.htm as long as possible.

NiCad, or nickel cadmium, batteries were once the most commonly used laptop batteries. They not only held less power than later models, but they could only be charged a limited number of times. If they were recharged before they were completely drained or if they were left on the charger after being charged, they quickly lost their power.

The next battery developed was the NiMN, or nickel metal hydride battery. Although the NiMN battery could hold more power than its predecessor, it still had a less severe version of the memory problem experienced with the Nicad. As a result, new technology developed the Li-lon, or lithium ion, battery. While the lithium ion battery still holds comparable power to the nickel metal hydride, it has several advantages over both older models. Not only is it lighter, but it has no memory effect.  For the laptop that supports a Li-lon battery, this is by far the best choice. Another advanced choice for some laptops is the Li-Poly battery.

While some of these batteries are more efficient than others, they all must be properly cared for in order to ensure their longevity and function. Some experts recommend fully draining all batteries and recharging them every few weeks to maintain their full capacity. Others say that this is not necessary for Li-lon batteries
If it is necessary to store a laptop battery for several months, the battery should be discharged to half of its full power and removed from the computer. If a partially drained battery is stored indefinitely, it may lose its ability to be charged fully. If it is completely discharged before storage, it may completely lose its capacity to be charged. Climate is, also, an issue. All laptop batteries may be damaged if stored in temperatures above 95 degrees or below 50 degrees Fahrenheit.

With the proper care http://www.adapterlist.com/dell/d820.htm and careful selection, not only can users ensure they have the most powerful, longest-lasting battery for their laptops, but they can have a trustworthy back-up, as well.
