Does notebook batteries need to fully discharge to activate

Notebook battery maintenance How can we use for a long time? The problem is different to say, many people are confused to know about the new lithium-ion batteries used in the time to completely washed three times to activate the battery discharge, every month to discharge the battery completely red, and so on, but how Why buy new when to come back three times a month and complete discharge Chong Chong discharge, many people do not know much about. To do this, I refer to the relevant information and sorting out for public consultation.
The new IBM thinkpad t40 battery can be put in charge of deep lithium-ion batteries to upgrade the actual capacity of it? See the information in it does not show Yes, I also asked an expert for this, experts say it is meaningless. Can not think of the use of so-called three times before the release of the all-sufficient "activate" what is necessary. However, we later put in charge of deep marked the capacity of why change it?
Notebook computer lithium-ion thinkpad t43 battery used in general management with a chip and charge control chips. The "management chip" in a series of registers, there is capacity, temperature, ID, state-of-charge, discharge, such as the number of values. These values are in use will gradually change. "Charge control chips" to control the main battery charging process. Lithium-ion rechargeable battery process is divided into two phases, the current phase of the fast charge (when the battery indicator light yellow) and reduced voltage current phase (the battery indicator light flashes green. Filling phase of the fast current, battery voltage and gradually increase To the standard battery voltage, then under the control of the chip into the phase of the constant pressure, higher voltage is no longer sufficient to ensure that they are too, along with the current battery of 0 to weaken gradually increased, and the final charge. In the thinkpad r50 battery inside There is a statistical power chips, will be recorded through the red discharge curve (voltage, current, time) can calculate the sample battery power, this is what we read in Battery Information in the wh. Value. The lithium-ion batteries used in many , The discharge curve may change if the chip has been no opportunity to once again read out a complete discharge curve is calculated by the power that is not accurate. So deep need to calibrate the battery to take charge of the chip.
I personally believe that in the notebook computer for use in "a month after the full charge should take a" leading role of these amendments is to be improper, the value of the register, making the thinkpad r51 battery charge control and battery with a nominal capacity of the line The actual situation. A battery capacity and how to use the time to decide on its own battery manufacturing of individual differences, rather than using the method. A cell more than its rated put the number of red, so be careful and pay attention to how normal and will not extend its life. Therefore, the use of thinkpad r40 battery , should not be too deliberate to protect, in accordance with the normal peacetime use of it.
