How to Take Care of laptop battery

When a laptop battery is built, the clock begins ticking on its lifespan. At most, a laptop battery can last for five years. If the battery is not used properly, you may need to replace laptop battery very soon  in one or two years. There are two important factors when it comes to battery maintenance: charging and temperature. How the batteries are charged, and the temperatures to which they are exposed, are key factors that determine their lifespan. Most laptop batteries these days are lithium-ion batteries. Lithium-ion batteries are substantially better than either of their precursors; nickel cadmium and nickel metal hydride batteries, in that they do not suffer from the "memory effect". This means that, contrary to popular belief, you do not need to let your battery run down all the way.Many people use their laptops largely as desktop replacements, using them on the desk and leaving them plugged in most of the time. These people would do well not what their laptop batteries charge constantly. Although there's no danger of "overcharging" lithium-ion batteries, leaving a laptop plugged in for months at a time will have a detrimental effect on its battery. If you use your laptop as a desktop replacement, try unplugging it when it's not in use. Take care to unplug the charger from the wall, too, as otherwise it consumes electricity. Better yet, leave the laptop plugged in all the time, but remove its battery. For long-term storage, lithium-ion batteries should be allowed to run down to little below half charge. Store them safely in a warm, dry location.When using a laptop as a desktop replacement the battery should not be left in for long periods of time. The laptop will over time discharge the battery. Remove the battery, making sure that it is charged to 50% and store it in a dry, warm place. Ensure that it is wrapped protectively and nothing will be dropped on it. The battery should be re-installed every 3-4 weeks and allowed to fully discharge. Leaving a battery in storage for longer than this without using could cause the battery to fully discharge as the circuitry of the battery itself consumes power.How to charge your laptop batteryFor first use, it is always advisable to discharge the Dell laptop battery to 3% and then fully charge it (around 12 hrs).Do not let the battery discharge to 0% initially, as it makes the battery prone to damage/short.Battery once used must be recharged within 2 days without fail with above 50% before using it.Dell battery needs to be discharged to 3% and then fully charging twice a week.Use cooling pad while using notebook or laptop for longer time.
