DELL Vostro V130 Laptop 12cell Battery Use Manual : 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 Vostro V130 battery charger 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. Otherwise, it will accelerate the aging batteries scrapped. If the relatively high capacity (such as more than 80 percent) under the charge of the case, will accelerate the aging of the DELL V130 ac charger. 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 brand new V130 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 DELL V130 battery voltage, charge it to about 50 percent's energy and tak
