There are three main types of laptop batteries - Nickel Cadmium (NiCd), Nickel Metal Hydride (NiMH) and Lithium Ion (LiON). They vary in cost, weight and specifications. Lithium Ion (LiON) batteries are usually 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 not that heavyweight as NiCd and NiMH laptop batteries and have not got any memory effect. If used in the proper way, lithium ion batteries are expected to run for about 3 years, but it is necessary to note that the three-year period starts as soon as batteries are manufactured and not when you start to use them. A laptop battery requires to be replaced when the pc cannot function anymore unless connected to the supply of electricity via an adapter. Here are a few guidelines to prolong laptop battery's life. • Frequent complete discharges of a battery shorten its longevity. Partial discharges with frequent recharges are preferable for lithium-ion batteries than a complete discharge. Recharging partly charged LiON batteries does not cause harm, since there is no memory. Reduced battery's life in a laptop primarily depends on the high temperatures rather than charge - discharge patterns. • It is advisable to fully discharge a pc battery after thirty charges. Otherwise, the fuel gauge will get significantly less accurate and can cause a premature cut-off of the device. • Make use of coolers (readily available on the market) for the laptop temperature to meet the established limits. • Consider removing a battery from a laptop when it is run on a fixed power. (Some laptop makers are worried about moisture and dust accumulating inside the laptop battery casing.) • Avoid purchasing spare LiON batteries for later deployment. Observe dates of manufacture. Never buy old stock, even if it is sold at lower costs. • If you have got a spare LiON laptop battery, use one to the full and keep the other one cool by placing it into the refrigerator. Do not freeze the laptop battery. For longer storage, keep the laptop battery at a 40% charge level. Before deploying any pc, read a manual instruction supplied.
