There are 3 main types of laptop batteries - Nickel Cadmium (NiCd), Nickel Metal Hydride (NiMH) and Lithium Ion (LiON). They differ in cost, weight and specifications. Lithium Ion (LiON) laptop batteries are usually recommended to use in laptops of the new generation. These batteries have enough power to run laptops as well as accessories, such as mp3 players, DVD players and USB devices. They are lighter than NiCd and NiMH batteries and have not got any memory defect. If used in the proper way, lithium ion batteries are expected to function for around 3 years, but it is necessary to point out that the three-year period of time begins as soon as batteries are actually produced and not when you start to deploy them. A pc battery requires changing when the PC cannot work any longer unless attached to the supply of electricity through an adapter. Beneath are several guidelines to prolong laptop battery's life. • Avoid frequent full discharges, because this puts added strain on a pc battery. Partial discharges with frequent recharges are preferable for lithium-ion batteries than a complete discharge. Recharging partly charged LiON batteries is safe, as they have no memory. Short pc battery's life in a laptop is normally resulted from high temperatures rather than charge - discharge patterns. • It is recommended to fully discharge a battery after 30 charges. Otherwise, the fuel gauge will become considerably less accurate and the pc can go dead prematurely. • Keep a lithium-ion laptop battery cool. • Remove a battery from a laptop when it is run on a fixed power. (Some laptop makers express concern for dust and moisture that accumulate inside the pc battery casing.) • Avoid buying spare lithium-ion batteries for later deployment. Pay attention to manufacturing dates. Never purchase old stock, even if it is available at lower prices. • If you have a spare lithium-ion pc battery, deploy one to the full and keep the other one cool by placing it into the fridge. Do not freeze the battery. For prolonged storage, keep the battery at a 40% charge level. Before exploiting any laptop, remember to read a manual instruction supplied.
