Skills out of depth of the error when changing
laptop computers equipped with original equipment batteries, after a period of time after use, there will inevitably be of standby time. Some users said: "The depth with repeated charge and discharge method, you can restore the performance of the battery, thereby extending battery life with a APple A1021 adapter." Comparison of this argument one-sided.
To understand this issue correctly, may start with the battery type used in laptop computers start with Acer Aspire 3000 battery. As you know, before 1995 the production of notebook computers are basically nickel-cadmium batteries to power. The battery is in use, if the charge-discharge method is not correct, the battery will have a "memory effect", thereby reducing the battery's actual capacity to eliminate this "memory effect" is used repeatedly in the best way to charge and discharge depth way. With the emergence of nickel-metal hydride batteries, battery capacity has significantly improved, but the "memory effect" did not completely eliminate the shortcomings.
In recent years, lithium-ion batteries in notebook computers has been rapidly growing popularity, due to lithium-ion batteries have basically eliminated the "memory effect" problem, it is used repeatedly to restore the battery depth of charge and discharge performance of the method no longer applies to powerbook g4 adapter. However, lithium-ion batteries why I still appear to reduce the capacity of the problem? The root causes of that situation, is used in notebook computers and the original lithium-ion battery built-in battery management system in the making.
Battery Management: At present, in notebook computers or Dell Latitude D800 Battery, almost all adopted the "battery management" and "charge-discharge control" two kinds of chip-level management system. The "battery management chip" placed in a notebook inside the chip to store the register of the computer used in the capacity of lithium-ion batteries, working temperature, ID, serial number, charge and discharge status, charging and discharging the accumulated frequency of important information. The data information in the use of the process to Dell Latitude D620 Battery, according to the actual situation of continuously updated. The battery built-in "charge-discharge control chip," the most important role is to monitor and control the battery charge-discharge process as a whole and be documented.
