27. Laptop Battery Use Manual
New laptop battery needs charging and discharging cycle first before the regular usage. Because battery from factory to the users' hands that exists the time differences, and the electrode materials will be its passivation for the battery of the longer time difference, which is why the purchase of new batteries need to be completely filled with charging and discharging cycle three times to eliminate electrode materials passivation, to activate laptop battery performance, to reach maximum capacity. Meanwhile, the laptop has the data transmission agreement end between battery and the computer, after the need of two or three times charged and discharged cycle, the percent of its real capacity can keep pace with the percent of content on the computer's screen. Cycle's steps: insert incomputer to discharge until the shutdown, and then recharge the battery, charging time must be over 12 hours, to repeat the action of charging and discharging for three times.

The proper use of laptop battery usually will be very crucial. Discharge can not fully take end, there are about 5 percent of electricity charging, we should not be spent replenishment. Otherwise, it will accelerate the aging batteries scrapped. If the relatively high laptop battery capacity (such as more than 80 percent) under the charge of the case, will accelerate the aging of battery. Use lithium ion batteries in 25 to 35 degrees centigrade, will show better performance. The low temperature or high temperature than the above state, its performance will be greatly devalued.

When using the battery, fever is a normal phenomenon, because in the process of the battery charged and discharged, energy conversion will result in heat and at the same time the amount of heat will be transmitted to the battery. But if overheated (burning), stop using it immediately and ask for the professinonals to check.

When not using it, charge it to about 50 percent's energy and take out of it from equipment and stored in temperature :10-20 degrees centigrade, humidity :45-75 percent. Do this each day and more than one charge, and discharge cycles to eliminate passivation of electrode materials, and activate battery performance.

Prevent the liquid entering into the laptop battery. Once liquid immersing into batteries, stop using it, dry with a dry cloth and put it in the ventilation to dry, otherwise they will result in danger.

Not arbitrarily demolish the battery. In order to prevent short circuit, do not use metal objects (such as necklaces, etc.) batteries hit the positive and a negative extreme.

Don't let the laptop battery near the fire source, not subject to any pressure, otherwise they will lead to danger.

If the laptop battery charged and discharged after three complete cycle, performance or significance still decline indicate that you should change the battery.
28. How do I maximize my laptop battery life?
Laptop battery life takes a important role for a mobile computer. Theres nothing worse than really needing to access you laptop only to have it by AC/DC adapter with power due to low battery. There are some tips that can help to prolong battery life.

The first thing to consider would be the conditioning of the laptop battery. More namely your charging habits. The worst thing you can do for your laptop battery is always keep it on the charger or charge it while its only half full. This will diminish the life of the battery giving you less hours of operating time. The ideal way to charge your laptop battery pack would be to use it until it is completely discharged and then charge it fully.

The second issue to consider would be your usage habits. Using multimedia such as movies and music will kill your battery a lot quicker. Especially doing operations that are CPU intensive. Playing games will diminish your power supply a lot quicker than say, browsing the internet.

There are also different settings that can help preserve your battery life. Windows has different functions for laptop. For instance you can set your power usage depending on what you are doing. You can set your laptop to act like a desktop if you are near a power supply to get the full performance out of your system. On the other hand you can also set it to use power as efficiently as possible if you are on the move. These setting change things such as the amount of power the CPU uses, the brightness of the screen and more.

In the end its up-to the individual user. Some laptops come with the option of a second battery which can double the power your laptop has at your disposal but this is often costly. Also there are more advanced batteries that can be used but again they will cost you extra.
