| There are 3 main kinds of laptop batteries - Nickel Cadmium (NiCd), Nickel Metal Hydride (NiMH) and Lithium Ion (LiON). They vary in price, weight and specific features.
Lithium Ion (LiON) batteries are usually used in laptops of the new generation. These batteries are powerful enough 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 no memory defect.
If deployed properly, lithium ion batteries commonly work for around 3 years, but it is necessary to clarify that the three-year period of time begins once batteries are manufactured and not when they are actually exploited. It is time to change a battery when the laptop cannot operate anymore unless attached to the main supply of electricity via an adaptor. Beneath are a few guidelines to prolong laptop battery's life.
• Avoid frequent complete discharges, as this puts extra strain on a pc battery. Several partial discharges with frequent recharges are better for lithium-ion batteries than a full discharge. Recharging partially charged lithium-ion batteries is safe, since they have no memory. Reduced laptop battery's life in a laptop is normally caused by heat rather than charge - discharge patterns.
• It is advisable to fully discharge a battery after thirty charges. Otherwise, the fuel gauge will become considerably less accurate and can cause a premature cut-off of the pc.
• Use cooling devices (available on the market) for the laptop temperature to comply with the established specifications.
• Remove a pc battery from a laptop when it is run on a fixed power. (Some laptop producers are worried about moisture and dust that accumulate inside the battery casing.)
• Avoid purchasing spare LiON batteries for later use. Pay attention to dates of manufacture. Never purchase old stock, even if it is available at lower costs.
• If you have a spare LiON battery, deploy one to the fullest and keep the other one cool by placing it into the fridge. Do not freeze the pc battery. For prolonged storage, keep the battery at a 40% charge level.
Before using any device, remember to read a manual instruction supplied. |
