Laptop batteries can be of three kinds - Nickel Cadmium (NiCd), Nickel Metal Hydride (NiMH) and Lithium Ion (LiON). They vary in cost, weight and specific features. Lithium Ion (LiON) laptop batteries are commonly installed in technically advanced laptops. These batteries have enough power to run laptops plus accessories, such as MP3 players, DVD players and USB devices. They are lighter than NiCd and NiMH laptop batteries and do not produce any memory defect. If deployed in the proper way, LiON batteries are expected to function for about 3 years, but it is essential to note that the three-year period starts as soon as batteries are actually produced and not when you start to use them. It is time to change a battery when the PC cannot function any longer unless attached to the main supply of electricity via an adapter. Here are a few guidelines to prolong pc battery's life. • Avoid frequent complete discharges, as this puts extra strain on a laptop battery. Several partial discharges with frequent recharges are preferable for lithium-ion batteries than a full discharge. Recharging partly charged LiON batteries does not cause harm, since they have no memory. Short laptop battery's life in a laptop is chiefly caused by heat rather than charge - discharge patterns. • It is advisable to fully discharge a pc battery after 30 charges. Otherwise, the fuel gauge will become significantly less precise and in some cases will cut off the pc prematurely. • A LiON pc battery should be kept cool. • Consider removing a pc battery from a laptop when it is run on a fixed power. (Some laptop manufacturers are concerned about moisture and dust that pile up inside the pc battery casing.) • Avoid purchasing spare LiON batteries for later deployment. Observe manufacturing dates. Never buy old stock, even if it is sold at reduced costs. • If you have a spare lithium-ion battery, deploy one to the full and keep the other one cool by placing it into the fridge. Do not freeze the laptop battery. For best results, store the battery at 40% state-of-charge. Before using any laptop, remember to read a manual instruction supplied. |
