As you buy a new laptop, the salesman will tell you that you should have the battery three times charge and discharge. Like this dell D610 battery, I have its power exhausted and then charge it for three times after the power has used up. I just do it as the salesman's recommend. But why should I follow this instruction. My friend is curious about his dell D600 battery and how to keep the battery working longer. Generally, it's hard to keep the battery's working time after month's usage.
As I asked some experts about the completely charge and discharge of the battery, they don't agree with the saying that the deep discharging can extend the battery capacity. This dell 6000 battery is a good example for it has not charge and discharge for three times. But now there is no big difference of its usage. And the capacity is not far away from other laptops. Therefore, I refer to the relevant information and organize it for reference.
According to the experts, it's unnecessary to activate the laptop battery through the deep charge and discharge for three times when you buy a new laptop. As the dell GD761 KD476 battery, it's the popular lithium battery with the management of chip and charge control chips. The "management chip" is in a series of registers. There is capacity, temperature, ID, charge status, and discharge times and other values. These values will gradually change. "Charge control chips" mainly control the battery charging process. As the Toshiba PA3399U-2BRS battery, the charging process is divided into two phases, fast charge constant current phase (the battery indicator light yellow) and constant current decline phase (the battery indicator light flashes green). Constant current fast charge phase, the battery voltage is gradually increased. The standard voltage of the battery, then if the control of the chip come into the constant voltage, the voltage will not rise to ensure that no over-charge.
Personally speaking, people are used to the three times charge and discharge. And I did so. If you didn't do by accident, there is slight harm to your laptop battery. The bad effect is slight. As the 6000 battery, it's still under perfect working condition.
