New battery needs charging and discharging cycle first before the regular usage. Because laptop 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 Thinkpad W520 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 notebook battery, charging time must be over 12 hours, to repeat the action of charging and discharging for three times.

The proper use of 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.

Do this each day and more than one charge, and discharge cycles to eliminate passivation of electrode materials, and activate battery performance.
