| Laptop batteries can be of three types - Nickel Cadmium (NiCd), Nickel Metal Hydride (NiMH) and Lithium Ion (LiON). They differ in cost, weight and specific characteristics. All advanced laptops have light lithium ion or lithium polymer batteries which are normally pre-installed in laptops. These batteries have enough power to run laptops and accessories, such as MP3 players, DVD players and USB devices. They are lighter than NiCd and NiMH batteries and have no memory defect. If deployed properly, lithium ion batteries are expected to function for about three years, but it is necessary to clarify that the three-year period of time starts as soon as batteries are produced and not when you start to use them. It is time to replace a laptop battery when the pc cannot work anymore unless connected to the main supply of electricity through an adapter. Beneath are some guidelines to prolong pc battery's longevity. • Avoid frequent complete discharges, since this puts added strain on a battery. Several partial discharges with frequent recharges are better for lithium-ion batteries than a complete discharge. Recharging partly charged lithium-ion batteries does not cause harm, since there is no memory. Short laptop battery's life in a laptop chiefly hinges upon the heat rather than charge - discharge patterns. • It is recommended to discharge a battery to the full after 30 charges. Otherwise, the fuel gauge will become significantly less precise and in some cases will cut off the device prematurely. • A lithium-ion laptop battery should be kept cool. • Remove a battery from a laptop when it is run on a fixed power. (Some laptop producers are worried about dust and moisture that accumulate inside the pc battery casing.) • Avoid purchasing spare LiON batteries for later use. Pay special attention to the date of expiration. Never buy old stock, even if it is available at clearance prices. • If you have a spare LiON battery, deploy one to the full and keep the other one cool by putting it into the fridge. Do not freeze the laptop battery. For best results, store the laptop battery at 40% state-of-charge. Before exploiting any laptop, remember to read a manual instruction supplied. |
