| At present the laptop has replaced the desk computer because it is compact, portable and mobile. You can take it on board an aircraft, on a yacht or elsewhere and continue working etc. The only disadvantage is that it has limited energy. Having been used for a few hours, the battery gets discharged and should be re-charged for further exploitation. Laptop manufacturers have not invented a laptop yet that can work all day long. nevertheless, several important steps forward have been undertaken to prolong battery's life. There are 3 major types of laptop batteries distinguished. The first laptop batteries to be re-charged were Nickel Cadmium (NiCd). They were reasonably priced and put out lots of power. Nonetheless, they were heavy and are no longer used now. Nickel Metal Hydride (NiMH) batteries are unsuitable for laptops of the new generation. Their output is higher comparing with NiCd batteries. Furthermore, they are considered to be safer and cheaper. The only drawback is the so-called memory effect they have. If the battery has not discharged fully, it will remember it and will produce less power than it should do. Lithium Ion (LiON) laptop batteries are usually used in highly advanced makes of laptops. They are not that quite heavy as NiCd and NiMH laptop batteries and have no memory effect. Nonetheless, they are rather expensive. Actually the price for a laptop depends upon how long you can make use of it. Thus, it mainly depends upon purposes you use your laptop for. Those who travel worldwide a lot, need an extended energy source. If it is time to replace your battery, ensure it is compatible with a laptop model, in spite of the fact that a lot of laptop batteries nowadays are compatible with all models. Afterwards consider 2 main ratings on it: Volts and Milliamps. The voltage is to be within 10% of the original battery voltage. When buying a battery, always look for the one with the biggest Milliamps. An external laptop battery is connected to a laptop via an AC adaptor plug consisting of an adaptor, a cord and 13 other connectors. When you purchase an AC adaptor, assure that it will suit the voltage and current output. This information is commonly placed on labels that can be found on your laptop and on the original adapter. The letter 'V' means voltage and 'A' or 'mA' - current output. The voltage figure should be within 10% of your original adapter voltage. The Amps figure can be higher but should not be lower comparing to the original current output. Make sure that the tip dimentions of an AC adapter and the shape of a battery you have picked out are similar to the original ones. Certainly, any device requires appropriate use. Laptop energy sources are no exception. Keep and use them correctly and they will serve you longer. |
