What are the repair methods for cell phone lithium batteries?
Lithium batteries do not need to be fully charged and then turned off. This is because when the mobile phone is fully charged, the voltage inside the battery increases, thereby increasing the load on the battery. Therefore, mobile phone charging can be plugged and unplugged as long as it can be used normally. ?
Since lithium batteries themselves do not have a memory effect, they do not need to be charged to 100% every time. Additionally, lithium batteries are not resistant to overcharging. Continuing to charge after being fully charged will result in irreversible damage to the battery.
Detailed information:
1. Lithium batteries should avoid high and low temperatures
Some users want to increase When it comes to the battery life of a mobile phone, it is wrong to use it in a lower temperature environment. Not only does this approach not extend battery life, but it will also affect battery life. The reason is that lithium-ion batteries are subject to the adverse effects of "heat" and "cold", and the indoor temperature is the optimal temperature for smartphone batteries.
2. Lithium batteries do not require activation
Early nickel-cadmium batteries and nickel-metal hydride batteries require similar "activation". These batteries will produce a “memory effect”. Charging in an incompletely discharged state can easily overcharger the battery. However, the batteries used in current mobile phones are lithium-ion batteries, and therefore their initialization process has been completed during manufacturing. start using No activation required.

Charge your mobile phone. overnight harmful to the battery?
ElectricityThe battery is a very important part of the mobile phone. The mobile phone needs a battery to work, but after using the battery for a long time, there will be problems. So, how to repair cell phone lithium battery? Let me explain below!
How to repair the balithium battery of a cell phone
1. Use a clean eraser or use cleaning tools made from other materials to gently wipe the metal contacts of the lithium battery and the metal contacts of the cell phone, which will improve the charging status and durability of the power supply.
2. Wrap the old cell phone lithium battery that will automatically turn off in plastic wrap and try to wrap it as tightly as possible, with a total of three layers inside and outside, to make sure the battery is in an empty state. Then wrap three layers of newspaper outside the plastic film to completely seal the lithium battery. Place it in the freezer layer of the refrigerator. After 48 hours, remove the battery and remove the six layers of wrapping paper one by one. There is no expansion of ssurface or deformation of the lithium battery due to freezing. After cooling for a while, then charge.
3. Fully discharge the almost discarded lithium battery, then recharge it to activate the battery. The specific method is: deep discharge of the mobile phone is to achieve deeper recharge by exhausting the internal power, which requires unconventional methods.
Use a specific device to connect the cell phone to a small low-voltage light bulb. The energy inside the battery will be transferred to the small bulb until all the light is emitted. "Cell phones must slowly drain due to lower voltages. Under normal circumstances, if the cell phone is connected and is lower than the rated voltage of 3.6 volts, it will automatically turn off after discharge, the battery of the mobile phone recharged." can be used longer.
The lifespan of lithium batteries is about 600 times. If charging times are too long, the thermal movement of the molecules will gradually destroy the microstructure of the internal molecular arrangement and charge storage efficiency will gradually decrease. "The freezing process can easily destroy the original internal structure of the battery. It can increase the charging capacity in a short time, but it may not be effective for long-term use," said Professor Ye. The microstructure of the lithium battery is destroyed, it needs to be completely restored. It It is impossible that long-term use of this method will accelerate the loss of cell phone battery
Regarding the "activation" problem of lithium batteries, many opinions are as follows: Charging time should be more than 12 hours, and charging and deactivationFull charges must 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.
Proper maintenance of lithium batteries
1. Mobile phone batteries are most afraid of high or low temperatures
1. above 100℃
It will seriously affect the battery life and energy storage capacity. It may cause the battery to melt or explode. Therefore, please keep lithium batteries away from fire and other heat sources.
2. High temperature of 35℃ to 100℃
Yes, you read correctly, from 35℃ (human body temperature is generally 36.2℃ to 37.2℃), battery life begins to be affected. Temperature has an obvious impact, and the higher the temperature, the greater the impact.
The rated life of lithium batteries is at least 800 times fully charged and discharged. Based on the average charge of a mobile phone once per day, a battery should last approximately three years. But the vast majority of batteries don't last that long. This is largely explained by the fact that the battery is affected by the temperature of the human body, and by the heat generated by the other chips of the mobile. phone.
Why do laptop batteries always seem to last less than cell phone batteries? This is because: Firstly, laptops generate a lot more heatwhen they work than cell phones, and the heat from the computer chip is easily transmitted to the battery. easy to exceed 40℃. Second, in order to charge faster, laptops generally have higher charging current and larger battery capacity, and the battery itself generates heat during charging and discharging. Third, the battery is usually located on the bottom panel, making it less likely to dissipate heat.
Also, if your device generates more heat during use, such as making long calls on your mobile phone, playing large games on your mobile phone, or playing games on your laptop, this heat will be conducted to the battery, In addition, the heat generated by the battery itself during charging will not pose a safety risk, but it will also affect the battery.
So if you find that the device is noticeably warm while charging (like an iPhone playing 3D games while charging), you might consider waiting until it is fully charged before charging. play with the charging cable.
3. Below -40 ℃
It will reach the freezing point and freeze completely.
4. Low temperature from 10℃ to -40℃
This will reduce battery life, but will not cause permanent damage to the battery as long as the temperature returns piece. .
2. Ideal condition of lithium batteries
It is more suitable that the working environment temperature of lithium batteries is around 20 ℃ (almost at 'interior). Temperature). At this time, the battery discharge and charge performance can be maximized. If you want to leave the battery inactive for a long time (more than three months), be sure to charge it to approximatelyn 40% before leaving it inactive (forget it for a short time, the key is the problem). For this reason, when the battery leaves the factory, the battery factory charges it to 40% before leaving the factory. The lower the temperature of the unused battery, the slower it will age, but it should not be lower than -40℃.
Proper use of lithium batteries
1. New batteries: No treatment is required, such as activation, etc., and can be used normally. directly.
2. Batteries that have not been left unused for a long time (within three months): do not require any treatment (such as activation, etc.) and can be directly used normally.
3.Batteries left unused for a long time (more than three months) can be activated to bring the battery activity to its highest level, or to not allow it tonaturally return to its highest activity with normal use.
4. For electronic product evaluators, to ensure accurate battery life statistics, it is necessary to perform activation processing before testing.
The right way to charge your cell phone
Don't worry, charge it whenever you want and you can stop charging at any time no problem. scruples. This is an important advantage of lithium batteries: no memory effect. But don't wait until your phone runs out of power and automatically turns off before recharging it. It is also necessary to carry out a full cycle of discharge and charge at least once a month, that is, use the phone's energy to less than 20%, then charge it up to until it is full. Once it's full, let it charge. some time. Bref, just one sentence to summarize: recharge as you go, don't wait for it to run out to recharge, recharge it once a month.
Lithium Battery Dangers
Will charging the cell phone overnight damage the battery?
< p>Mobile phones are basically charged once a day, and the battery is very big. Some people choose to charge it before bed, charge it overnight and then unplug it the next day. So, does it harm the cell phone? Come take a look together.Nowadays, in many cases, people are inseparable from their cell phones. In order to resurrect their cell phone in full health the next day, they charge their cell phone before going to bed at night so that we can sleep. All night long. This only lasts one full night of charging. Many people wonder if this will damage the battery.erie of their cell phone? How to recharge your cell phone battery so it lasts longer?
First of all, we need to clarify one problem, that is, the battery of current mobile phones is different from that of previous mobile phones. Do not charge it for more than ten hours when using it for. first time, because current mobile phone batteries are all lithium-ion batteries, they do not have memory function and can be charged at any time even if they run out of power.
Today, technology is more and more developed, and the security performance of mobile phones is getting stronger and stronger. Most mobile phones have charge protection features when your mobile phone is fully charged, even if it is mobile. The phone charger is not unplugged, the mobile phone will shut downalso automatically charge to protect the lithium battery of the mobile phone. Once the mobile phone is charged to more than 95% power, the mobile phone will start charging with micro current. without damaging the battery.
Of course, if the mobile phone is charged for a long time, the battery of the mobile phone will be in a high voltage state, which will shorten the battery life of the mobile phone.
So, is it better to load up on everything at once, or eat less and eat more often? Obviously, the latter solution is preferable. Frequent shallow charging and discharging of lithium-ion batteries will do more to extend battery life than deep charging and discharging. Therefore, when the cell phone battery is not enough, charge it if it is. not fully charged, you can unplug it,no need to charge too fully.
But don't use the phone while charging. When the temperature of the place where the phone is charged is too high and the phone is too hot, it is best to unplug it to reduce damage to the battery. of the phone, so that it can be used longer and have better battery life.
Lithium batteries are not safe.
Lithium batteries also have a risk of exploding, but the risk is not that high. It can also be said that all batteries are dangerous and carry risks, and according to the data, although lithium batteries. explode The risk is very low, but the risk of spontaneous combustion of lithium batteries is relatively high. In fact, excellent and regular high-quality lithium battery brands have done enough work in all aspects ofLithium battery production, from battery cells, external structures, the entire battery and the entire vehicle system, they have a set of rigorous and rigorous tests. safety standards. System design, manufacturers have minimized risks before products leave the factory, eliminating any safety risks.
