Tips on taking care of Your Laptop battery

Most laptop batteries these days are lithium-ion batteries. Here is some tips I summarized on the web to protect lithium-ion (Li-ion) batteries.

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. 

How the batteries are charged, and the temperatures to which they are exposed, are key factors that determine their lifespan.

Many people believe that low temperatures are harmful for batteries.The truth about Li-ion batteries is that high temperatures are their worst enemy. Therefore, the following tips will help avoid laptop batteries from getting too warm.

1. Don’t put it on your lap or on thermal insulating materials such as cushion.

2. Try to avoid charging the battery while you are working with the laptop. Charging the batteries increases your laptop’s temperature. The problem is that the CPU, the graphics card and the hard disk also heat up your laptop, which adds to the temperature increase experienced when charging the battery. Many vendors deliver their laptops with software that allows you to disable charging. You also can remove the battery while you are working on AC current.

3. Make sure the laptop’s ventilation can always work properly. Don’t place objects before the ventilation systems opening. Don’t run or charge the laptop while it is in its case

4. Don’t leave the laptop in the car or under the sun in summer. Use a bike. It keeps your laptop battery cool and your own battery healthy. And too much sun exposure causes only skin cancer anyway. 

If your laptop's battery has already run out, do not despair. If you ever thought that laptop batteries purchased from the manufacturer were ridiculously overpriced, you were right. In fact, the cells in your laptop's battery may only be worth about $20.
