| It might have already happened to you several times when in an extremely important instant when you were working or expecting an urgent e-message, your laptop switched off, because its battery had gone low. In such cases the battery should be re-charged or replaced. There are 3 major kinds of laptop batteries - Nickel Cadmium (NiCd), Nickel Metal Hydride (NiMH) and Lithium Ion (LiON). They differ in cost, weight and typical characteristics. Yet, the charging procedures have a lot in common. The charging time for brand new batteries should average at 14-16 hours. If you are going to re-charge old ones, first and foremost let them cool off, because overcharging will decrease their life. When using NiMH batteries, remember they have the so-called "memory effect". Thus, when a NiMH laptop battery is not discharged to the full, it will "think" that it has, for instance 50% of its original power, and will use only this 50 percent, thus decreasing the time during which you can use your laptop. Laptop batteries are re-charged in different ways. The first method is when you use AC power. The so-called "trickle charge" automatically re-charges batteries after a laptop has been disconnected. A second way is an external battery charger. All you need to do is to put batteries into a charger which is connected to the supply of electricity via an outlet. Batteries' life can also be prolonged if: - you fully charge and discharge batteries; - you run programs on your laptop that you truly need. Downloading music to your iPod, surfing the Net, chatting online along with using other programs can considerably shorten batteries's life. - you use laptop batteries' power wisely; - you defrag the hard disk from time to time, as it saves space and, therefore, power; - you adapt screen brightness; - you make use of cooling devices (available on the market) for the laptop temperature to meet the established limits; - you use AC adapters whenever it is possible. Surely, it is absolutely necessary to use a laptop and its various power devices in accordance with the safety requirements to secure your laptop will function long. |
