| Laptop batteries are of three kinds - Nickel Cadmium (NiCd), Nickel Metal Hydride (NiMH) and Lithium Ion (LiON). They vary in cost, weight and specifications.
All modern PCs have lightweight LiON or lithium polymer batteries that are usually pre-installed in 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 no memory defect.
If exploited in the proper way, LiON batteries usually work for around 3 years, but it is important to clear out that the three-year period begins when batteries are manufactured and not when you start to use them. It is time to replace a battery when the laptop cannot work any longer unless connected to the supply of electricity through an adapter. Here are several guidelines to prolong pc battery's life.
• Frequent complete discharges of a laptop battery shorten its longevity. Several partial discharges with frequent recharges are better for lithium-ion batteries than a full discharge. Recharging partly charged LiON batteries does not cause harm, as they have no memory. Reduced battery's life in a laptop is commonly resulted from heat rather than charge - discharge patterns.
• Batteries with fuel gauge (laptops) should be calibrated by applying a deliberate full discharge after30 charges. Otherwise, the fuel gauge will become significantly less precise and in some cases will cut off the device prematurely.
• Deploy cooling devices (widely available on the market) for the pc temperature to meet the set specifications.
• Consider removing a pc battery from a laptop that is run on a fixed power. (Some laptop producers express concern for dust and moisture that accumulate inside the pc battery casing.)
• Avoid purchasing spare LiON batteries for later use. Observe the date of expiration. Never buy old stock, even if it is available at lower prices.
• If you have got a spare LiON laptop battery, deploy one to the full and keep the other one cool by placing it into the refrigerator. Do not freeze the battery. For best results, store the pc battery at 40% state-of-charge.
Before using any laptop, remember to read a manual supplied. |
