| Laptop batteries come in 3 kinds - Nickel Cadmium (NiCd), Nickel Metal Hydride (NiMH) and Lithium Ion (LiON). They vary in cost, weight and specific characteristics.
Lithium Ion (LiON) batteries are commonly used in technically advanced makes of laptops. These batteries have enough power to run laptops as well as accessories, such as MP3 players, DVD players and USB devices.
They are not that heavyweight as NiCd and NiMH laptop batteries and do not produce any memory defect.
If used properly, LiON batteries are expected to work for approximately 3 years, but it is essential to note that the three-year period begins as soon as batteries are actually made and not when they are actually exploited. A laptop battery should be replaced or re-charged when the pc cannot work anymore unless connected to the supply of electricity via an adapter. Beneath are some guidelines to prolong pc battery's life.
• Frequent complete discharges of a battery make its longevity shorter. Several partial discharges with frequent recharges are preferable for LiON batteries than a full discharge. Recharging partly charged LiON batteries does not cause harm, because there is no memory. Reduced laptop battery's life in a laptop normally hangs on the heat rather than charge - discharge patterns.
• It is recommended to fully discharge a laptop battery after 30 charges. Otherwise, the fuel gauge will get significantly less precise and in some cases will cut off the pc prematurely.
• Keep a lithium-ion battery cool.
• Remove 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 battery casing.)
• Avoid buying spare LiON batteries for later deployment. Observe manufacturing dates. Never buy old stock, even if it is sold at clearance costs.
• 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 refrigerator. Do not freeze the laptop battery. For optimum results, store the pc battery at 40% state-of-charge.
Before deploying any device, read a manual supplied. |
