Buying a New Twinhead Laptop Battery

Laptop batteries don't last forever. If you've had your Twinhead notebook computer for a while, you may notice that you can't have it unplugged for as long as you used to. When it starts dying while you're on the road and need it to work, it's probably time for a new battery. Replacing your Twinhead laptop battery (http://www.laptopbattery.net/twinheadbattery.htm) can seem intimidating, but there's no need to worry. Just follow our tips to make your purchase successful.

Getting the Right Laptop Battery

The key to finding the battery that works with your computer is your laptop's model number. It's not enough to find batteries that are compatible with the Twinhead brand; you must also find a battery that is compatible with the specific model that you have. Some replacement batteries are compatible with multiple computer models. Matching up the specific laptop model number of your computer with a number that the batter is compatible with will ensure that the replacement battery will work with your Twinhead laptop.

Matching Up Physical Factors

Once you have a battery with the correct model number, you should be set. However, it doesn't hurt to do a couple double checks. First of all, is the replacement battery the same size and shape as your old battery? Compare the two and make sure the new laptop battery will fit in the same space on your computer.

Another physical characteristic of your new battery that should be the same as your old battery is its internal chemistry. Just as computer technology is constantly developing, so is laptop battery technology. If your computer is a newer model, it may have the latest in laptop battery technology, which is lithium-ion (Li-ion). If your notebook computer is a bit older it may use nickel cadmium (NiCd) or nickel-metal hydride (NiMH) batteries. A computer that works with nickel-metal hydride batteries will not normally work with lithium-ion batteries, for example, so make sure that the technology level of the replacement battery you buy is the same as that of the old battery you are replacing.

Where to Buy Replacement Laptop Batteries

If there is a store where you have purchased Twinhead accessories or had repairs done in the past, you may want to check to find out if they offer replacement batteries as well. If not, or if you don't have a favorite store, then consider shopping for your new battery online. Many online retailers make shopping easy by allowing you to search by the brand and model number of your notebook computer. When you've matched up the model number, you will know you have the right Twinhead laptop battery.

Avoid Used Laptop Batteries

When shopping online you will probably see some retailers offering “refurbished” laptop batteries. These are best avoided. Used laptop batteries inevitably have shorter lives and less power than new batteries; the technology to rejuvenate an old battery fully simply does not exist. No matter how low the price on the refurbished laptop battery may be, it will not be the better value.

Shopping and Comparing Batteries

Especially if you are shopping online, it can be easy to compare prices on the battery you need. Just remember that there are some questions to ask yourself as you shop in addition to price. Does the retailer offer a warranty? If so, how long is its coverage? Look for a warranty of about a year to guarantee your battery's performance. Are there extra costs you will have to pay? Some online retailers charge more for shipping and handling while some offer shipping for free. Make sure to account for these additional factors to be certain that you are getting the best deal on your new Twinhead laptop battery.
