New DELL KY266 PT435 NM633 laptop batteries need charging and discharging cycle first before the regular usage. Because KY266 PT435 NM633 battery from factory to the user's 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 DELL KY266 PT435 NM633 battery's performance, to reach maximum capacity. Meanwhile, the KY266 PT435 NM633 laptop battery 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 into computer to discharge until the shutdown, and then recharge the DELL KY266 PT435 NM633 batteries , charging time must be over 12 hours, to repeat the action of charging and discharging for three times.
When using the battery for DELL KY266 PT435 NM633 batteries, fever is a normal phenomenon, because in the process of the DELL KY266 PT435 NM633 battery pack 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.
