How to use the newly purchased mobile phone battery?

How to use the newly purchased mobile phone battery? Cell phone battery life is limited and we need to use new cell phone batteries properly. So next I will lead you to know more about how to use the newly purchased cell phone battery.

How to use the newly purchased mobile phone battery 1

Today's mobile phone batteries are almost all lithium batteries, and new batteries no longer need to be charged for 12 hours for the first time. If the new cell phone battery is charged properly, it is the best maintenance for the battery.

Operation method

1. Firstly, do not use the mobile phone while the battery is charging. ESince the voltage of the cell phone when charging is higher than the voltage of the cell phone when standby, if the quality of the cell phone charger is not good, there may be electricity leakage or even explosion of the cell phone battery.

2. Do not wait until the phone is completely discharged before charging it. When the phone tells you that the remaining power is less than 20% or 10%, be ready to charge the phone. Charging the cell phone battery a small number of times will help the battery maintain its active state and extend the life of the cell phone battery.

3. Do not frequently use mobile power sources, cars and computers to charge mobile phone batteries. Charging and discharging cell phone batteries requires stable voltage and current. If the voltage andcurrent charged for a long time is unstable, the mobile phone battery may be damaged.

4. You should also pay attention to charging the cell phone battery in a normal temperature environment. Try not to charge the cell phone battery in an environment where the temperature is higher. than 45 degrees and below zero. Otherwise, the battery will accelerate its aging and even explode in a high temperature environment.

Lithium battery storage < /strong> p>

Primary lithium batteries have a very low self-discharge and can be stored for 3 years. The effect will be better if stored in refrigerated conditions. It is a good idea to store primary batteries atlithium in a low temperature place.

Lithium-ion batteries can be stored for more than six months at 20°C, because their self-discharge rate is very low and most of their capacity can be restored.

The phenomenon of self-discharge in lithium batteries. If the battery voltage is stored below 3.6V for a long time, the battery will overdischarge, destroy the internal structure of the battery and decline. battery life. Therefore, lithium batteries stored for a long time should be recharged every 3-6 months, that is, charged to a voltage of 3.8~3.9V (the best battery storage voltage lithium battery is about 3.85V) is suitable and it is not suitable for being fully charged.

Lithium batteries have a wide application temperature range. They can still be used outdoors during the northern winter,but the capacity will be greatly reduced if they return to room temperature, the capacity can be restored.

Notes:

Primary lithium batteries:

Unlike lithium-ion batteries, they cannot be loaded. , charging is very dangerous. Other considerations, equivalent to lithium-ion batteries.

Maintenance instructions:

When charging, it should not be higher than the maximum charging voltage, and when discharging, it must not be lower than the minimum. operating voltage.

Lithium-ion batteries must remain above the minimum operating voltage at all times. Low-voltage over-discharge or self-discharge reactions will cause lithium-ion active materials to decompose and destroy, which is not necessarily the case. be restored.

Any form of overchargingage of a lithium-ion battery can cause serious damage to battery performance or even an explosion. Lithium-ion batteries should avoid overcharging the battery during the charging process.

Do not frequently discharge or deeply charge. However, every 30 charging cycles, the power detection chip will automatically perform deep discharge and deep charge to accurately assess the battery condition.

Avoid high temperatures, which can shorten service life at best and cause explosion in severe cases. It can be stored in the refrigerator if possible. If the laptop uses AC power, please remove the lithium-ion battery strip to avoid being affected by the heat generated by the computer.

Avoid freezing, but the freezing point of most lithium-ion battery electrolyte solutions is -40°C and is not easyand to freeze.

If not used for a long time, please store it between 40% and 60% of the charging capacity. When the battery is too low, it may cause excessive discharge due to self-discharge.

Since lithium-ion batteries age naturally when not in use, you should choose according to your actual needs when purchasing and avoid buying too many.

Charging the cell phone battery

Cell phone batteries are energy storage tools which power cell phones. Cell phone batteries are generally used. These are lithium batteries and nickel metal hydride batteries. “mAh” is the unit of battery capacity and the Chinese name is milliampere-hour.

Regarding the “activation” problemion” lithium batteries, many opinions are: the charging time should be more than 12 hours, and full charging and discharging should be repeated three times in order to activate the battery. This claim that “the first three charges take more than 12 hours” relates to rechargeable batteries from the 1990s. Nickel-cadmium batteries then had a memory effect and had to be fully charged to ensure battery capacity. The mobile phone uses a lithium-ion battery that has no memory effect and can be fully charged in 2-3 hours. If the first three times of charging and discharging a new battery actually lasts 12 hours or more, it will cause serious damage to the battery and may cause it to swell or even burn. Fortunately, the cell phone and charger have protection circuits when charged to 100%, they will automatically cut off.ent power and do not continue to charge when plugged into the charger. However, it is better to unplug the charger at this time to avoid overcharging the battery in case there is a problem with the charger's protection circuit, causing serious damage to the battery material and affecting its capacity and lifespan. life. Usually, the charging method described in the mobile phone manual is the standard charging method suitable for the mobile phone.

Charging method

1. The mobile phone battery consists of three parts: the battery core, the protection circuit and the housing. Currently, mobile phone batteries are all lithium-ion batteries (often called lithium batteries in non-standard situations), and the cathode material is lithium cobalt oxide. The standard discharge voltage is 3.7V, the teCharging cut-off voltage is 4.2 V and discharge cut-off voltage is 2.75 V. The unit of power is Wh (watt hour). Since the standard discharge voltage of cell phone batteries is uniformly 3.7 V, mAh (milliamp hour) can also be used instead. The conversion relationship between these two types of units on cell phone batteries is: Watt-hour = Ampere-hour × 3.7.

2. Overcharging, overdischarging and short circuit will seriously damage the battery performance and may cause use hazards. For this reason, cell phone batteries usually have a thin protective circuit board to prevent these risks.

3. Feeders are divided into direct feeders and seat feeders. Direct charging converts 220 AC mains power into 5 V DC, which is input into the mobile phone and is stepped down by the circuit de charge the mobile phone to be used by the battery. Generally, it will be delivered when purchasing a mobile phone. The pedestal charger is directly connected to the battery and converts the mains power into the voltage required for the battery to use.

4. If you want to use a charger, try to choose original or high quality products. If the base charging circuit is of poor quality, there will be charging risks.

5. Lithium-ion batteries have no memory effect, but are inert if not used for a long time, they may become passivated after being rinsed several times, the best performance can be restored.

6. Lithium batteries do not need to be specifically discharged before being charged. Some fast chargers only indicate 90% full charge when the light changes, and the charger automatically switches toslowly charge to fully charge the battery. But generally speaking, as long as it shows full, it can be removed.

7. In order not to damage the battery life, it is best to charge slowly when charging; the time does not have to be too long.

8. There is self-discharge in cell phone batteries, as over-discharging will damage the battery. If the cell phone battery is not used for a long time, it should be ensured that it is equipped with a battery. certain amount of power.

9. Although our mobile phone is within the network coverage area, our mobile phone is no longer able to receive and make calls when the mobile phone is turned off and charging. At this time, we can use the missed call forwarding function of the mobile phone to transfer the mobile phone to the phone.one fixes around us to avoid the loss of incoming calls. This method is suitable for mobile phones that are not in the network coverage area or. This also applies when the signal is weak and cannot be connected temporarily.

10. Do not expose the battery to high temperatures or intense cold. For example, during summer days, you should not leave your phone in the car to expose it to the scorching sun or take it. Place it in an air-conditioned room and place it 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's best to charge at room temperature and not cover the phone with anything.

11. The longer the charging time, the better. For lower quality batteries without protective circuitstion, charging should be stopped once they are fully charged. If not used for a long time, the battery should be separated from the mobile phone.

12. The newly purchased battery does not need to be charged for 12 hours for the first time, but it is better to do a full charge and discharge process for 3-5 hours . 100% normally, and full discharge means the mobile phone uses low power when recalled. Because the battery needs to go through filling, forming, electrolyte charging and discharging, capacity sharing and other processes before leaving the factory, so that the battery is in an activated state. However, after leaving the factory, it takes at least one month. a year before it can reach the user's hands. Because the battery is automatically due to the influence of discharge, the material of the batterie becomes passivated at this point, the battery can be activated by full charge and discharge.

What should be noted when using lithium batteries is that the battery enters a dormant state after being left for a period of time. At that time, the capacity is lower than the normal value and the usage time is also lower. shortcut. However, lithium batteries are easy to activate. After 3-5 normal charge and discharge cycles, the battery can be activated and restored to its normal capacity. Due to the characteristics of the lithium battery itself, it has almost no memory effect. Therefore, the user's new mobile phone lithium battery does not require special methods and equipment during the activation process. Not only is this true in theory, but in my own practice, the "natural activation" method of loading usingstandard methods from the beginning is the best.

12. Nickel chargers and lithium chargers cannot be used Mix it.

How to use lithium batteries correctly?

There are certain effects. It is not recommended to recharge the lithium battery once it is exhausted.

The correct use of lithium batteries can be summarized in the following three points:

1. Charge according to standard time and procedures even for the first three times (especially; no (extra long charge more than 12 hours);

2. When the lithium battery displays a battery prompt low while driving the electric vehicle, the lithium battery should be charged as soon aspossible. (Fast charging stations are strongly discouraged, as they can seriously damage the battery. All opinions in the market regarding recharging the battery after it runs out and charging the battery for a long time are not correct. It depends also of the type. of battery. To "try to maximize the power of the electric vehicle battery" The practice of "using it once it runs out, it is best to use it until it can no longer be used." "operate" is actually only used on nickel batteries to avoid battery memory effects.);

3. There is no need to specialize in the activation of lithium battery electric vehicles. According to this method, the lithium battery will be naturally activated when the electric vehicle is driving.

Lithium electric vehicle charging instructions

1. Place it to recharge:

The battery has some remaining power before leaving the factory, and it can also be driven short distances after the electric vehicle is sold. After the first trip, the battery must be charged for the first time. It is recommended to carry out the first charge for a longer duration (8 to 12 hours).

The battery should be charged in time after use and should not be stored at a loss. If the battery has not been used for more than two months, the battery should be fully charged. If the battery is left for more than 5 months, it must undergo a charge and discharge cycle. Regular use of the battery and regular charging of the battery during normal use and long-term storage can ensure the best practical effect of the battery and prolong its life.urea of ​​life.

2. Normal charging:

The normal battery charging method is as follows:

First connect the charger and the battery to be charged, then connect the power plug of the charger to 220V AC power supply. (This connection sequence will prevent sparking when plugging and unplugging the charging plug.) When the device is turned on, the charger will display a red light indicating that the battery is charging normally. Charging may take 6-8 hours.

3. Charger Notes:

In order to ensure the charging safety of the battery and ensure the life of the battery, the 3 test is equipped with a special charger for lithium batteries . Do not use lead chargers or other forms of chargers for charging.

How long does it take to charge a new lithium battery?

1. Moderate charge

Keep the lithium-ion battery moderately chargedAged and discharged can extend battery life. Keeping the lithium-ion battery power between 10% and 90% is beneficial to protect the battery when charging batteries of mobile phones, laptops and other digital products, it is not necessary to reach the maximum value.

2. Choose the appropriate charging temperature

Lithium battery charging temperature range: 0-45 degrees Celsius, lithium battery discharge temperature range 0-60 degrees Celsius.

3. Avoid overcharging

Lithium-ion batteries should avoid overcharging during the charging process. Any form of overcharging lithium ion batteries will result in serious damage to battery performance or even an explosion. .

4. No activation is required for the first flush, standard charging time

Charging and discharging characteristics of lithium batteriesm and nickel batteries are very different. Charging time should be longer. 12 hours, and repeated three times, charge according to the standard time and standard methods, especially do not charge for more than 12 hours.

Detailed information:

1. Avoid charging at excessively high temperatures

If lithium batteries are used in an environment above the specified operating temperature, i.e. above 35°C, the battery power will continue to decrease, that is, the battery power duration will not be as long as usual.

If the device is charged at such temperatures, damage to the battery will be greater. Even storing batteries in a hot environment will inevitably cause corresponding damage to the quality of the battery. Therefore, try to maintain a temperature of fProper operation is a good way to extend the life of lithium batteries.

2. Avoid charging at too low temperatures

If you use lithium batteries in low temperature environments, i.e. below 4°C, you will also find that the battery life Battery life is reduced. . Some mobile phones The original lithium battery cannot be charged even in a low temperature environment. But don't worry too much, this is just a temporary situation, different from using in high temperature environments. Once the temperature rises and the battery molecules are heated, the battery immediately returns to its previous capacity.

3. Use often

Life is in movement. If you want to maximize the performance of a lithium-ion battery, you need to use it frequently to maintain the electrons in thelithium battery in a fluid state. If you do not use lithium batteries frequently, remember to cycle the lithium battery every month and perform power calibration, that is, deep discharge and a deep load.

3-5 hours.

3-5 hours When charging the lithium battery of an electric vehicle, it should be charged according to the standard time and procedures. The general charging time is 3-5 hours, and there is. no information listed online. “The first three times should be enough for 18 hours.” During the lithium battery charging process, when you find the charger indicator light turns green, keep charging for about 1-2 hours, then you can stop charging.
