Understanding the Memory Effect: The battery memory effect refers to reversible battery failure, that is, battery performance that can be restored after a failure. The memory effect refers to the automatic maintenance of this specific trend after a failure. A specific work cycle for a long time. This was first defined in nickel-cadmium batteries. Nickel-cadmium batteries do not have a memory effect, and today's sintered batteries have a memory effect (nickel-metal-hydride). hydride) are not linked to this definition of the memory effect, but are inert. They must be activated the first few times. Generally, they can be charged and discharged 300 to 500 times. shorter and shorter, so short that you want to change phones. It is best to put the old battery in the refrigerator for a few days before using it again.
Lithium.the batteries are different from nickel-metal hydride batteries and do not have a memory effect
How long does it take to charge the computer for the first time
Used a lot The battery is a lithium-ion battery. Lithium-ion batteries have no memory performance but are very inert. It takes about 12 hours of charging to activate. However, manufacturers now perform an activation process before leaving the factory, so the first few times of a new battery are usually: Does not take 12 hours to charge the battery during the first three adjustment periods. When purchasing the battery, the seller will tell us that it takes 12 hours to charge the battery for the first three times.
This was the charging time of the previous nickel series batteries. The correct time is 4-6 hours, and it is better to turn off the battery once it runs out, then recharge it, which is nnatural. After the adjustment period, Re-flush means that after flushing, everything will be fine for another half hour, or about two and a half hours. The battery typically needs to go through about 10 rinse and discharge cycles. get the best effect! It is normal for 2128 series batteries to have a short standby time after the first few charges. After about 10 charge and discharge cycles, the ideal standby time can be achieved, which is usually around 4 days. The first three times of charging last 4-6 hours, then each time of charging lasts 2.5 hours.
There are two popular sayings about the first three times of charging:
< p>1. Buy a machine When charging, let it charge for more than 12 hours2. Secondly, it is best to charge for 1-2 hours after it is fully charged.
The first is charging the nickel-metal hydride battery. In the past,nickel-metal hydride batteries were used. Since nickel-metal hydride batteries have memory capabilities, it is best to recharge them after using them for the first three. times for 12 hours to allow the batteries to be fully activated and achieve good results. This is common practice, so sellers used to say it, but now this has changed.
Lithium batteries do not need to be charged for as long. Lithium batteries are inert, but very small. They have been pre-activated before leaving the factory, so the new batteries always have some power, after three long charging times, they will heal. slowly by itself. Using the battery itself is also an act of battery activation. In addition, the memory capacity of the lithium battery is very small, so there is no need torecharge after each use. be stable, in order to obtain good results. Lithium batteries have overflow protection, starting with large batteries. After charging, it is a trickle charge. Once the battery is fully charged, the power will be automatically cut off. The effect of recharging is not significant, and overcharging may cause a large discharge cycle, which may damage the battery. over time. This is the case the first three times. You can recharge it and use it later. It is recommended to recharge it after use to extend battery life. In the future, charging will consist of charging for about an hour after a full charge. Frequent charging is not recommended because the lifespan of a lithium battery is related to the number of times it is charged. Generally, the lifespan of a lithium battery willrie depending on its capacity, but it is roughly 300 to 700 times, so frequent charging and. discharging affects battery life and is also bad for the charger.
A battery can be charged and discharged approximately 500 times. The standby time of 2128 series battery can reach about 4 days after several charge and discharge cycles. It can therefore be used for approximately 3 years. years After 2128 it was removed, so one battery is enough! Battery life is measured by the number of charge and discharge times. If the battery is charged before it is exhausted, it will shorten the battery life. Generally, the current lithium-ion battery life is about 500 charging and discharging times. It is therefore recommended to exhaust the battery as much as possible before recharging it.
If the user wishes to extend the effective use time of the batteryie, in addition to ensuring the quality of the charger, correct charging techniques are also essential, as poor quality chargers or incorrect charging methods will affect the battery. Regarding the usage time and battery life, here are the charging tips:
1. Before the battery leaves the factory, the manufacturer has activated and precharged it, so the battery has residual power. Some friends said that the battery is charged according to the adjustment period, but the standby time is still seriously insufficient. This is indeed a real battery, in this case, the adjustment period needs to be extended and then fully charged and discharged 3-5 times.
2. If the newly purchased battery is lithium-ion, the first 3-5 charges are generally called the adjustment period and must be charged for more than 14 hours to ensure full activation of lithium activity-ion. Lithium-ion batteries do not have a memory effect, but have high inertia. They must be fully enabled to ensure optimal performance for future use.
3. Some automated smart fast chargers only indicate that they are 90% full when the light changes. The charger will automatically switch to slow charging to fully charge the battery. It is best to use the battery after it is fully charged, otherwise the usage time will be shortened.
4. Lithium batteries do not need to be specifically discharged before being charged. Improper discharge will damage the battery. When charging, try to charge slowly and reduce fast charging; the time should not exceed 24 hours. Only after the battery has undergone three to five complete charge and discharge cycles will all of the chemicals within it be "activated» to obtain optimal use.
5. Please use the charger from the original manufacturer or a reputable brand. For lithium batteries, use a special charger for lithium batteries and follow the instructions, otherwise the battery will be damaged or even dangerous.
6. Many users often leave the battery on while charging. In fact, it can easily cause injury. service life, because during the charging process, the circuit board will heat up if there is an external call at that time, instant reflux current may occur, causing damage. damage to internal parts.
7. Battery life depends on the number of repeated charges and discharges. You should therefore try to avoid charging when the battery has residual energy, as this will reduce its lifespan. When the downtime exceeds 7 days, the battery must be fully discharged and fully charged before use.ilization.
8． All batteries discharge automatically. When not in use, nickel-metal hydride batteries discharge approximately 1% of their remaining capacity each day, and lithium batteries discharge 0.2% to 0.3% of their remaining capacity each day. day. When charging the battery, try to use a dedicated socket and do not share the socket with the charger, TV and other household appliances.
9． Although it is within the network coverage area, it is no longer able to receive and make calls when turned off and charging. At this time, the unreachable transfer function that can be used will be transferred to the nearby landline to avoid the loss of the incoming call. This method is also applicable when the call is not in the network coverage area or the signal is weak and. cannot be connected temporarily.
10．Do not expose the battery to high temperatures or intense cold. For example, during the scorching days of summer, you should not put it in a car to expose it to the scorching sun or take it to an air-conditioned room and place it; in a place where the air conditioner blows directly. When charging, it is normal for the battery to be a little warm, but it should not withstand the “suffering” of high temperatures. To prevent this from happening, it is best to charge at room temperature and not cover anything.
11. The nickel-cadmium (N iCd) battery must be completely discharged before recharging, and the battery must be fully charged after recharging.
12． If the battery has been left unused for too long, it is best to contact the maintenance department to request lifetime treatment of the battery. You can also use a DC voltage regulator yourself to adjustr the voltage to 5 ~ 6 V and the current. at 500 ~ 600 mA and connect the battery in reverse. Note that you can release it as soon as you touch it and repeat up to three times. After this process, use the original charger to charge during the "adjustment period".
13． The longer the charging time, the better. For batteries without protection circuits, charging should be stopped once they are fully charged, otherwise battery performance will be affected by heat or overheating.
14. Lithium-ion batteries must use a special charger, otherwise they may not reach saturation and affect their performance. After charging, avoid leaving it on the charger for more than 12 hours, and separate the battery when not in use for a long time.
1. When charging for the first time, you need to charge the battery continuously for 12 hours, then chcharge and fully discharge 3 times to fully wake up the new battery.
2. If you use external power for a long time, it is best to remove the battery. Many friends have not noticed this problem. Failure to remove the battery when using an external power supply not only affects battery life, but also increases the heat dissipation burden of the laptop, thereby shortening its lifespan.
3. Load and unload regularly. Although a lithium-ion battery without memory effect has a certain inertia effect, prolonged non-use will cause the lithium ions to lose activity and need to be reactivated. Therefore, if you do not use the computer for a long time (3 weeks or more) or find that the battery charging and discharging time becomes shorter, you should dischargefully drain the battery before charging. Generally, fully charge and discharge at least once. a month.
4. It is best to turn off the laptop when charging so that the battery can be fully charged. Do not unplug the power source while charging. Turning the battery off will reduce charging time by more than 30% compared to turning it on, and it can also extend battery life. It is best to use it 30 minutes after charging.
5. Avoid exposure to sunlight, moisture, corrosion caused by chemical liquids, and short circuits caused by contact between battery contacts and metal objects. The number of charging and discharging times of lithium batteries generally does not exceed 800 times. Each time they are charged, their lifespan is shortened.
Remarks onr loading the computer
1. Use the original charger to charge the laptop.
2. When the laptop is charging, do not touch it with wet hands.
3. Do not deliberately charge the laptop once it runs out of power. This is not good for the battery. The computer can be charged when the battery is about 8%.
4. Don't charge the laptop battery too fully and recharge it when you have time.
