New SONY Vaio Vgn-cr540e/L 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 SONY Vaio Vgn-cr540e/L 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 SONY Vaio Vgn-cr540e/L battery capacity (such as more than 80 percent) under the charge of the case, will accelerate the aging of SONY VAIO VGN-CR540E/L laptop 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 SONY Vaio Vgn-cr540e/L laptop battery, fever is a normal phenomenon, because in the process of the Vaio Vgn-cr540e/L 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 SONY Vaio Vgn-cr540e/L 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 Sony Vaio Vgn-cr540e/L battery. In order to prevent short circuit, do not use metal objects (such as necklaces, etc.) batteries hit the positive and a negative extreme.
