Mobile phone battery is a kind of energy storage tool, which provides power for mobile phones. Generally, mobile phone batteries are lithium batteries and nickel-hydrogen batteries. In the process of using mobile phones, we often encounter various problems such as battery damage and shortened life. How can I repair and maintain my mobile phone battery?
How to repair and maintain the mobile phone battery 1 how to maintain the life of the mobile phone battery?
1, avoid overcharge and overdischarge: As mentioned above, the best charging range of mobile phone battery is 20-80%. In order to make the mobile phone battery have a longer life, we can try to control the battery capacity within this range when the mobile phone is in normal use, which can slow down the capacity attenuation of the mobile phone battery.
2. Charging environment: The life of lithium batteries will also be affected by the charging environment. Too high or too low charging environment will have adverse effects. Needless to say, if the temperature is too high, the lithium battery can't work normally at low temperature, so it is better to charge at room temperature as much as possible.
3, fast charge: Today's hottest fast charge will actually cause some damage to battery life. The scheme of high voltage can not avoid the increase of the temperature of rechargeable battery, which will cause side reactions inside the battery; The large current scheme is more likely to cause the SEI film of the battery cathode to rupture to a certain extent, which will react with the electrolyte and affect the battery life.
Maintenance and correct use of lithium battery
1. Lithium-ion batteries have a long life.
As we all know, lithium-ion batteries have a limited number of times to charge, but at the same time, lithium-ion batteries, like anything else, have a life. So the next time you buy a battery, remember to look at the production date of the lithium-ion battery. Of course, the newer the better. Because your lithium-ion battery began to "die" from the moment it left the factory. The life of lithium-ion batteries depends on many factors. In the best case, your lithium-ion battery will lose 20% of its maximum power within one year from the factory.
2, don't let your equipment completely dead.
Perhaps you have wondered why your mobile phone, PDA or iPod will light up the LCD screen when it is almost dead, tell you cheerfully, "Your battery is dead" and then turn it off automatically. The reason is very simple, because there is a circuit inside the mobile phone, and the battery will automatically turn off when it is too low. This circuit is set to protect the mobile phone. You can understand it this way: If your lithium-ion battery is too low, it may permanently damage your lithium-ion battery. So you can plug in the power supply and charge it as easily as possible.
Remember that the "one-time" charging cycle means that you use 50% of the electricity on the first day, charge at night and use 50% the next day. This is a cycle.
Continuous and repeated charging of lithium-ion batteries will not reduce battery life.
3, to prevent the battery temperature is too high
Lithium-ion battery will not be overcharged, it is protected by internal circuit. The biggest fear of lithium-ion batteries is that they are too high. Temperatures exceeding 40 degrees will reduce the amount of electricity that lithium-ion batteries can charge.
How to repair and maintain the mobile phone battery? 2 How to prolong the service life of the new mobile phone battery?
The ultimate goal of mobile phone battery maintenance is to prolong the life of mobile phone battery, so that mobile phone battery can serve us for a longer time after one charge.
1, pay attention to the charging of new mobile phones.
The batteries of the newly bought mobile phones are all lithium batteries, and the manufacturers have activated them, so each new mobile phone battery will have residual power. Therefore, the first three to five charges of the newly purchased mobile phone are the adjustment period, and should be kept for more than 14 hours each time to ensure the full activation of lithium ions and achieve the best use effect.
2. Lithium batteries don't need to be discharged and should be charged as slowly as possible.
Many friends think that mobile phone batteries should be discharged first and then recharged, which is wrong. Lithium batteries are unnecessary, can't discharge, and now they have no discharge function.
In addition, it is recommended to charge slowly as much as possible to reduce the loss of mobile phone batteries. Note: No matter slow charging or fast charging, it should not exceed 24 hours, otherwise the battery will be burnt out due to the huge electron flow generated by long-term power supply.
Don't cut off the power supply immediately after it is fully charged.
When the mobile phone battery is charging, if the mobile phone or charger shows full, please don't turn off the power immediately, because the mobile phone battery is actually only 90% charged at this time. You should charge the battery for a period of time before using it, otherwise it will shorten the use time.
4. Try not to open it when charging.
If the mobile phone is still on when charging, the battery of the mobile phone will discharge outward because of the' use' of the mobile phone, and power will be supplied inward because of the charging of the battery, which is likely to cause voltage disorder and cause the circuit board of the mobile phone to heat up. If there is an incoming call, it will generate instantaneous backflow current and damage the internal parts of the mobile phone.
5. Recharge after the power is used up.
The charging times of the mobile phone battery determine the life of the battery. Generally, a lithium battery can be continuously charged and discharged for about 500 times, and then the battery performance will be greatly weakened. Therefore, it is recommended that you try to recharge your mobile phone battery after it is exhausted or automatically turned off.
6, pay attention to protect the mobile phone battery
If you want to maintain your mobile phone battery in place, you should also pay attention to protecting it. Therefore, don't put the battery in a hot or cold place, like dog days, and don't expose the mobile phone to the sun; Or take it to an air-conditioned room and put it in a place where the cold wind blows directly. When charging, the current product refluxes, and it is normal for the battery to get a little hot.
7. It needs to be activated if it is not used for a long time.
If the cell phone battery is not used for a long time, you should first go to a special cell phone repair point to activate the battery, or you can use a DC constant voltage device to adjust the voltage to 5~6V and the current to 500~600mA to reverse the battery. Note: hair-trigger, repeat up to three times. After this treatment, the original charger is used for "adjustment period" charging.
8. The charging time is not as long as possible.
When charging a mobile phone, it should be noted that the longer the charging time, the better. If there is no protection circuit or a non-genuine battery, it should be powered off immediately after it is fully charged, otherwise the performance will be affected by heat or overheating.
The battery capacity can be divided by the output current of the charger. For example, if the output current of a battery with a capacity of 800MAH is 500MA, the charging time is equal to 800MAH/500MA= 1, 6 hours. Of course, this is only a theoretical calculation of fully charged time. When the charger shows that the charging is complete, it is best to charge the battery for about half an hour. Special charger must be selected for lithium-ion batteries, otherwise it may not reach saturation state and affect performance.
9. The new battery is fully charged and discharged.
After long-term use, the contacts will be oxidized, resulting in automatic shutdown of the mobile phone or automatic disconnection during the call. At this time, you can wrap a paper towel with a small cotton swab or toothpick and wipe it with a little alcohol. Never scratch with hard objects, which will aggravate poor contact. No alcohol can be replaced by highly alcoholic liquor. Immediately after wiping, dry it with a paper towel to avoid the short circuit between the two poles of the battery caused by alcohol overflow. The chemicals in the new battery will be fully "activated" after 3-5 complete charge and discharge cycles to achieve the best use effect.
10, using the original battery of the mobile phone manufacturer.
Remind netizens, please try to use the original mobile phone batteries and chargers provided by mobile phone manufacturers, or use regular products, and don't buy mobile phone batteries and chargers in street stalls or unreliable places.
