Out of the notebook battery errors
Notebook convenience of the most important in the life of the battery capacity, battery life of notebook directly determine the length of the notebook’s convenient, with the use of laptop batteries can be in any office or place of entertainment, convenience, you are not on the battery Time is running short and the use is very troubling, notebook batteries in the end should be and how to use the correct maintenance, said online options are really correct? Many friends from the notebook’s battery charge and discharge, there is always a lot of errors in the on-line knowledge there are a lot of misunderstanding, to give you the following examples
A misunderstanding: the number of rechargeable battery life decisions
We use the notebook, with the exception of the occasional need to use outside the battery power supply to most of the time at home are the direct use of power, in order to save generally will not take down the battery, but the battery case with direct use of power Perhaps some people will tell you: Do you use such a cell would adversely affect battery life, because then every time the power is a necessary and sufficient electricity, one day charge 3 to 4 times the battery is only 500 times the number of charge, perhaps less than half a year on batteries Waste, so that you will remember that this battery life is 500 times the number of charge, that is, even if one day charging only once, only less than 2 years, so we use power when the battery is removed.
Clearly from the mainstream on-line maintenance of the battery, this is not reminded of the truth in the day-to-day use, should be to minimize the number of rechargeable batteries, notebook batteries, after all, have a memory effect, part of the charge (less than 100%) will lead to battery Batteries of chemical performance, often several times a day in Plug Power, and notebooks equipped with a battery, which means that every time Plug Power will be a charge, and on one charge, battery charging in the number of charge cycles (Also known as life) in relation to a reduction in the end lead to the battery can not be full of electricity, reducing the time range, which is why a lot of friends, his laptop battery only 80% capacity range from 3 hours 1 hour turned into points.
However, the number of rechargeable battery life can really affect you? In fact, Conceptually, the number of rechargeable batteries and battery life has no direct bearing on the ultimate decision is the battery life of the battery charge cycle, if we find out “the number of charge” and “charge cycle” of the relationship, understand How the matter. Charging the battery from the cycle is the first time or the depth of discharge, until the next time the depth of discharge. The charge refers to a number of charge cycles to the number of electric charge, in general, in charge of a cycle, the number of rechargeable lithium batteries in the 400 to 1,000 times, but lithium batteries are generally 100 to 300 charge cycles , And the battery charge each time only by the memory effect, the internal battery of chemical composition and physical activity will not disappear, the number of rechargeable batteries will continue to charge others to complete the cycle.
Misunderstanding two: a new notebook to be three times charge-discharge
You buy a new laptop after using the boot when the battery is only found in more than 20 minutes of the time, we usually have to charge for the first time that the charge-discharge three times, and every time charge to 12 hours or more.
It can be compared to the same car, buy a home to go through a period of running-in period, but the laptop batteries, lithium batteries, despite the activation of cell batteries, but we have to know that the notebook batteries at the factory, manufacturers have After activation of cell batteries, and batteries in the package into a notebook’s battery when activated after the equivalent of a test, which is why buy a notebook to go home after the first boot with a 3% when the battery power, this is the vendor After testing the charge for the first time there is no doubt that this fact has been activated cell batteries, the user can take charge to use the normal way, will not affect battery life and performance of the play.
If you have to believe that the new notebook’s battery charge and discharge process needs three times, it can only increase your workload, but also waste a lot of battery charge of the three cycles, only an increase in unnecessary loss of battery. More importantly, the charge for the first time to charge more than 12 hours, 36 hours on three occasions, and this is nothing but a waste of time, because notebooks are now with a lithium battery, lithium battery with a smart charge-discharge control circuit, unlike earlier Ni-MH battery as the need to manually control the charging time, the smart lithium battery charge and discharge control circuit to identify the course of charge when the battery is full, the charge current will be automatically cut off, and most of the rechargeable lithium battery only 4 to 6 hours can be Full, continue to charge 12 hours a waste of their time.
Three errors: the depth of discharge can enhance the capacity of the battery
A year ago to buy notebook computers, often due to the use of battery-powered, the battery is fully charged, the battery life is only about half an hour, when everyone on the depth of discharge that can enhance the capacity of the battery, increasing battery life. However, once the discharge was found, in fact, battery capacity has not increased, but also reduce a little bit because of a reduction in the battery charge cycle, battery capacity will decrease, but a lot of friends there is such a misunderstanding, that the depth of Can discharge the battery to enhance the actual capacity.
First of all, we know that because of the number of over-charging, the battery charge in the first cycle of the range on the decline, this time due to the effect of making memory chips can not identify the battery capacity, there will be no full power, battery capacity less than 40 Minutes, we have to discharge their operation to repair the battery capacity, but can not raise the actual battery capacity, because the end of the first charge cycle, so that the depth of discharge the battery charge into the next cycle, but each dropped a charge cycle, The batteries have a certain decline in the total power consumption, such as batteries discharge depth of 10, will retain the original power of about 80%, and 200 times the depth of discharge, the battery may be only 30%, to the first 300 charge cycles come to an end on A.
It is clear that when the actual capacity of the battery and control circuit record is not the same capacity, on a battery charge and discharge depth of the operation, so that the control circuit record, so that the battery close to the actual situation, this is the real capacity of the battery so that reflected, not Enhance the capacity of the battery, even though some of the battery calibration software can increase the battery capacity, but this software is a “virtual” upgrade, since the actual battery capacity at times and often can not control circuit record in the same capacity, the ratio of two low , That may be required to repair the discharge operation, and when a higher rate, the battery may be deliberately false correction software, and therefore would like to remind you that regardless of how the correction process battery discharge, and its actual capacity will not change Or even lower.
Misunderstanding four: long-term need on a regular basis do not have to charge and discharge
As most of the time to use the laptop at home, so most people are basically using the power supply, in order to reduce the number of battery charging, the battery will get you put down a drawer, but experts say there has been no batteries do not use, Otherwise, the battery will gradually expire, even if no batteries, preferably full of electric discharge or after taking off place, but the best for about a month to conduct a battery charge and discharge. There is no doubt that this is the majority of users would be a more accurate method of battery maintenance, if you think this operation is not troublesome, and every month to remind ourselves that charge and discharge, then have to tell you that in a waste of time, some of the Operation is likely to seem futile, but it is not a good thing.
First of all, make it clear that if the battery charged when not to place a long time, most likely due to the preservation of the environment and to allow the loss of electricity, and then loaded into a notebook found no electricity, and at this time can continue to use it to recharge. However, the storage battery, whether it is full of electrical discharge or after the preservation, with the remaining 1% of the battery, 30% or 50% of the electricity, and so there is no difference between preservation, on the contrary, fully discharged batteries will save the loss of activity and even lead to control Circuit protection and self-locking no longer be able to use the full power will bring long-term preservation of the security risk, and to preserve its battery life is most affected by high temperature and humidity, as long as the battery on the humidity 30% to 80% in room temperature Between 10 ~ 30 ℃, the basic question of what will not.
Many users believe that even if the battery is not in use, but also the total monthly charge, discharge time, the memory effect of a strong Ni-MH battery, it is very clear that this step is necessary, but the memory effect of lithium batteries is relatively low, and There is no need to charge and discharge once every month, have been frequent charge-discharge cycle is not only a waste of time, but will reduce battery life, of course, despite the notebook lithium batteries have not completely eliminate the memory effect, but has been greatly reduced memory effect, if Batteries do not have long-term, it is necessary to 3 to 4 months of the first charge and discharge, but not full or complete discharge, even if the discharge to the notebook are not open, this time on The lithium battery of belonging to a greater depth of the discharge of the injury, Tend to be counter-productive
