Is it normal for the design capacity of the laptop battery to change after manual calibration? Thank

In fact, the design capacity is not a standard value, but an estimate, if it is an excellent quality battery, the actual capacity just bought is often slightly more than the design capacity. After use, the capacity of the battery will slowly decrease with the number of charges.

The manual calibration mentioned by the landlord actually has no special need, if it is only to measure the actual capacity of the battery, if it is a professional worker this can be understood, instead of, it will only reduce the number of battery consumption, generally speaking, the actual life cycle of lithium battery is more than 200 times. If you discharge it once, you will reduce the use cycle by one time.

And how do I think the landlord's approach is to eliminate the battery memory effect, of course, the memory effect of lithium batteries is very small, not nothing, as a long-term reliance on the battery to use, it is still necessary to do this every other month.

Normal. Battery life will wear down, and no matter how much maintenance you normally use, the power will always get less and less.

It is enough to discharge once per discharge, there is no need to put it so many times, that is just to make your battery consume more quickly Shut down and unplug the power !

The design capacity desing capacity is generally unchanged, what changes is only the actual capacity on the circuit board, what you see should be the actual capacity of the battery (full chage capacity), which will change with it.

The battery is a must-have spare part for laptops. In use and charging, the problem of battery capacity dropping, that is, the problem of calibrating the battery, will be encountered. So, is it necessary to calibrate the battery, and how to calibrate the battery?

The answer is yes. Because this drop is not due to battery aging, proper calibration can restore this portion of lost capacity. And the battery should be calibrated regularly, say once in 1-2 months.

Laptops like Compaq and IBM provide battery calibration in the BIOS or power management program, so friends from these two brands can do as prompted. For those users who don't offer this feature, follow the steps below.

1.Set the screen saver to None.

2.In Windows Power Management, set the power usage scheme to "Always On" and set the Shutdown Device related menu below to "Never".

3.In the Alerts tab, set the Low Battery Alert to 10% and the action to No action; Set the "Critical Shortage of Battery Alert" to 3% and the operation to "Standby".

4.The screen brightness is set to the maximum.

5.Confirm that all windows are closed and that all previously worked data is saved.

6.After confirming that the battery is above 80% charged, unplug the power supply and all external devices, and if the screen brightness automatically decreases, then turn it to the brightest.

Ok, you can go to sleep, the laptop will automatically shut down when the discharge is over. After that, plug it in and let the laptop charge. Note that be sure to wait until it is fully charged before turning it on, and then restore the power scheme to the settings before calibration.

The purpose of this is to allow the battery to continuously discharge at a low current, which is impossible to achieve in our daily use, because we will inevitably perform various operations that will cause the current to fluctuate up and down in a normal state.

Machines like IBM and Sony can detect the change in capacity before and after the battery, and other machines can check it with a program called batterymon, and you will find that the capacity is recovering little by little. However, the reminder here is that if your battery has aged due to overuse, then this palliative approach is useless.

This method is also recommended for those who have just arrived at the new machine: it is best to follow this method for 2 or 3 times before the LI battery is put into use, so as to maximize the best possible performance of the battery into the post.

1. The first choice is to press the "F2" key on the keyboard to enter the BIOS menu when the computer is turned on, and then select the arrow keys to enter the POWER menu;

2. After entering the power menu, you can see the "Start Battery Calibration" option, select and press Enter to execute;

3. At this time, you will see an English prompt, asking you to plug in the power adapter of the notebook to charge the battery, and when the battery is fully charged, the screen will prompt the user to disconnect the power adapter, and then the notebook will start to continuously discharge the battery until the battery computer is exhausted.

4. After a while, the whole process takes about 4-5 hours. After the battery is exhausted and automatically turns off, then connect the power adapter to charge the battery, but you don't need to turn it on, and after the charging is completed (with the charging indicator is off), the battery correction process is completed.
