One: the laptop is bought back to be full of OK - NO, actually charged three times
Activate a new battery, and want to make your laptop battery last longer, you must have a good start, you have to start from buying a notebook. The new notebook should have 3% power on the first boot. At this point, you should not use the external power supply, use up the remaining power in the battery until it is turned off, then charge it with an external power supply, and repeat it three times to activate the battery. Of course, there are also sayings that it is full of 12 hours. This is applicable to the early NiMH battery models without battery control circuits, but it is a joke for laptop batteries with intelligent charge and discharge control circuits. When the laptop battery is fully charged, the charging current is automatically cut off. All in all, it is very important to activate the battery. The main point is to recharge the photoelectric amount and perform it three times. This will lay a good foundation for future use.
Second: charging time is too long, multiple times of charging - the days of battery retirement are closer
Recharge after running out of power and avoid charging for too long. Whether your notebook uses lithium or NiMH, you must recharge the battery after it has been used up (the power is less than 1%). This is the best way to avoid the memory effect. Regarding the statement that lithium battery has no memory effect, this is the wrong guidance of the irresponsible business. Lithium battery also has a memory effect, but its memory effect is smaller than nickel-hydrogen. The same as the charging method of the mobile phone battery , when you charge the laptop battery, try to avoid too long, generally within 12 hours. As for precautions such as preventing exposure, preventing moisture, preventing chemical liquids from eroding, and avoiding contact between battery contacts and metal objects, it is not mentioned here.
It is a very effective way to minimize the number of times you use the battery. It should be known that the number of times of charge and discharge of the battery is directly related to the life. Each time the battery is charged, the battery advances one step further. It is recommended that you use an external power supply as much as possible. The battery should be removed when using an external power supply. Some friends often plug and unplug the power supply several times a day, and the laptop is equipped with a battery. In doing so, the damage to the battery is greater. Because each time the external power supply is connected, it is equivalent to charging the battery once, and the battery will naturally survive. In addition, it is best to turn off the charging, which can play a role in curing the battery.
Three: Correction can increase battery capacity - error
The so-called correction is when the actual capacity of the battery and the recording capacity in the control circuit are not the same, the battery is subjected to a deep charge and discharge operation, so that the control circuit refreshes the record to make it close to the actual situation of the battery, which is a true capacity of the battery. The operation is not to increase the capacity. The key factor here is the actual capacity of the battery. If the actual capacity of the battery is higher than the capacity recorded in the control circuit, the correction can make the battery appear to have increased capacity, if the actual capacity of the battery is greater than the control circuit. If the capacity of the record is low, the correction will make the battery appear to have a reduced capacity, which is why many people are arguing over the correction effect. Please remember that the correction is to make the actual capacity of the battery appear, eliminating the battery and the control circuit. Deviation, as to whether the displayed capacity will increase or decrease, this is determined by the state of the battery itself rather than your correction. It is very likely that the battery will be greatly reduced in capacity due to deep discharge damage during calibration.
Four: The battery is not working, then change the battery itself - many of the books have battery self-locking function, often not thankful.
Many people's batteries are such a fatal, manufacturers seem to have expected that some people will do so, many brands of laptop battery design are self-locking function, once the battery core is out of the control circuit, the circuit enters a self-locking state. Only use a specific means to unlock, before this control circuit will not work, that is to say, the battery is equivalent to scrap, laptop battery cells are not free to change the battery, if you have to change the battery is not, please remember to find a special The battery repair company came to fencing, and changed its own waste. The frustration and depression that failed after the effort was the worst.
Five: 99% has been charged less than 100%, continue to charge will explode - this chance is equal to my weekly lottery
There is almost no chance of a laptop battery exploding. At most, it emits high heat and causes the shell to melt, but it rarely causes an open flame. The few accidents that have been announced are actually caused by poor process during production and short circuit caused by use. Most of the short circuits will be broken by the protection circuit in the battery, unless there is a short circuit before the protection circuit (the previous COMPAQ laptop battery explosion time should be caused by this) The things I have seen in the notebook for more than three years have only seen two cases. On the contrary, there are a lot of such things in the mobile phone. In the final analysis, the quality of the battery is still a problem. The mobile phone has a large number of inferior assembled batteries, and the notebook computer almost never has such a battery, because no one has a large enough value. Production of compatible batteries.
The reason why the charge is less than 100% after 99% is often due to the deviation of the battery control circuit record and the state of the battery itself. The battery has never reached the voltage recorded in the control circuit, so the control circuit is always charged and charged, in fact, the battery Already full, this problem can usually be solved by correction, but it doesn't matter if it is not corrected, because most charging circuits will automatically disconnect after being unable to fill for a long time, even smart automatic record current 99% refresh to 100 %, even if it is a foolish design that keeps on, because the current is very small at this time and will not cause damage.
At present, there are basically temperature detecting circuits in the laptop battery. When the temperature of the battery is too high, the control circuit will forcibly disconnect the battery to prevent the temperature from rising further, so that the situation of the explosion is caused in the laptop battery. The odds are no less than the jackpot jackpot.
No matter how scientific maintenance measures are taken, the battery will age. If your maintenance is in place, using a battery once a week can still maintain 60%~70% capacity after one year.
