Using Tips:

• Upon initial use (or after a prolonged storage period) the battery may require two to three charge/discharge cycles before achieving maximum capacity
• If the battery will not be used for a month or longer, it is recommended that it is removed from the device and stored in a cool, dry, clean place at about a 50% charge level
• Leaving a battery in a laptop while using an electrical outlet for long periods of time will keep the battery in a constant state of charging up and that will reduce the life cycle of the battery

About Laptop Batteries

• Overview
• The widespread adoption of mobile devices such as cellphones and mp3 players, along with the increasing attention given to hybrid vehicles, has resulted in an explosion in the battery industries. Laptops are one of many benefactors. But laptops present a unique challenge. They require far more energy than smaller gadgets, while a low weight and small size are still important. Improving technology has done a lot to improve the quality of laptop batteries, but several issues remain unresolved.
• Types
  
   
  
  
  
• Developers of laptop batteries strive to minimize weight, size, and cost while extending the battery's charge and lifespan. As a result of their research, several different chemical compositions have been found to create different types of batteries. Older laptop batteries used various combinations of nickle and other chemicals with some success. The earliest batteries, referred to as NiCad, proved to be heavy and ineffective while being damaging to the environment. NiMH batteries, also using Nickle, proved to be more effective and less cumbersome. While both of these technologies are still used in laptops, Lithium Ion (Li-Ion) batteries have mostly taken over. Li-Ion batteries hold more charge per weight than any of the other combinations, and are produced with reasonable costs.
• Battery Care
  
  
  
• Proper care can extend the lifespan of a battery for years, depending on usage. Because laptop batteries can only handle a limited amount of charges, being careful not to overcharge is important. Laptops that are used primarily at home when plugged in should have their battery removed after being charged to their maximum potential. These batteries are in a continuous cycle of losing small amounts of power and then recharging which will diminish their life. But do not leave the battery unconnected for too long. It should be recharged and completely drained every few weeks. Even batteries that are frequently used should be worn down until the laptop shuts off and followed with a complete recharge once a month. This will strengthen the battery's ability to hold a charge. Batteries that are not in use should be stored in a dry area with a moderate to warm temperature.
• Replacements
• Replacement laptop batteries can be purchased directly from laptop manufacturers or from third party retailers. A proper fit can be found by matching part numbers which will be printed in the battery itself. While third party vendors may offer cheaper alternatives, check with the laptop manufacturer to be sure that they will not void the warranty. After receiving a new laptop battery it should immediately be worn to an empty charge. After the laptop shuts off the battery should be charged to maximum, and worn down once more. Finally, the battery can be recharged and used as normal. If the initial charging of the battery wears quicker than expected, don't assume that the item is defective. Some batteries will hold a sub-par charge until this breaking in cycle has been completed.
• Extending a Charge
• A laptop battery's charge can be greatly lengthened by some specific habits. The more resources a computer uses, the more energy it requires. As a result, minimizing the load on your laptop can result in a longer charge, which will also lengthen the battery's overall life. The single largest drain on a laptop battery is the screen. Be sure to reduce the brightness whenever possible. Intensive uses, such as music, games and movies, also drain the battery much faster than simply browsing the internet or working in a text document. If a laptop is being used to watch a movie, or any function that does not require an active internet connection, disable the wireless card. This can usually be achieved with one button press and it will disable an entire energy-sucking device. Finally, disable the sound on your laptop if you do not need it. In the end, anything that is not being used should be turned off.
• Warning
• Be sure to replace laptop batteries with approved models. Batteries with different chemical compositions require different charging procedures, and swapping them can be dangerous. Excessive heat can be created causing damage to the laptop or even fire. Special attention should also be given to third party batteries that may be designed in a way that they work on a variety of laptops, which can also result in a less than perfect fit for any one model. Follow proper recycling guidelines when disposing of old batteries. Special forms of recycling should be used to strip and isolate the harmful chemicals. Some battery manufacturers will even take back their old batteries to ensure their proper disposal. Batteries thrown into a landfill can leak heavy metals and other dangerous chemicals into the soil which results in deadly poisons entering underground waterways, and eventually a faucet.

How to Charge a Laptop Battery



All laptop computers come with a built-in battery to keep it powered on without the need of a connection to an outlet. The charge life on these batteries is limited to a couple of hours, so charging a battery is a must for continued performance of laptop mobility.

• Drain the battery as much as possible--the less charge on the battery the better. A cell charge from zero to full will increase the battery's load cycle consistency then if you charged from only half way.
• Connect the laptop's adapter into the computer. This peripheral accessory keeps the computer running when the laptop battery is out of power and charges a depleted battery supply.
• Wait for the battery to fully charge. Typically an icon on your computer will indicate that the battery is charging. You can still use the computer during this state, but it will recharge faster if you turn off your computer.
• Monitor the progress of your battery charge by checking the laptop's battery application. This will tell you information such as the amount of time needed for a full charge and the level to which the battery has been charged. Typically the battery application will mount itself on your task bar with an icon measuring your battery level. This can be right clicked to access other features such as battery output and energy saver.
• Remove the adapter--if you plan on running through the fully charged battery again--or the battery itself to run your laptop through the adapter. In either cases, this prevents the battery from becoming overcharged and lose its maximum charge potential under future load cycles.

How to Buy Replacement Laptop Batteries?

Need a replacement laptop battery? You don't have to buy an OEM battery that is expensive. You can buy after market batteries and save a bundle. Learn how now!

• Make sure that you buy the right replacement laptop batteries. If you are unsure of the model number for your laptop battery then you can easily find it on your computer. Go to the control panel, click Power Options, select the Power Meter tab and click on the battery icon. From there you should be able to determine the make and model number of your battery.
• Visit your laptop manufacturers website and search for the model number if you wish to purchase an OEM battery. OEM batteries are going to be more expensive but they will be more reliable. Be prepared to easily spend over $100 if you plan to buy an original battery.
• Enter the model number into your favorite search engine if you want to find after market batteries. Make sure to check the company's reputation before purchasing a battery that is not made by the manufacturer. Some after market batteries have been known to catch fire, not hold a charge and not charge at all.

NOTE:
