How to repair and maintain cell phone batteries
Cell phone batteries are energy storage tools that provide power for cell phones, and cell phone batteries are generally lithium batteries and nickel-metal hydride batteries. In the process of using cell phones, we often encounter cell phone battery damage, shortened life and other types of problems. How do we repair and maintain our cell phone batteries?

How to maintain cell phone battery life
1, avoid overcharging and overdischarging: As mentioned above, the optimal range of cell phone batteries is between 20-80%. If you want to get a longer lifespan from your phone, try to keep your phone within this range so that it can slow down the battery degradation.
2. Charging environment: Li-ion battery life is also affected by the charging environment, too high or too low charging environment will cause adverse effects. The higher the temperature, the lower the temperature of the lithium batteries simply can not work properly, so charging or try to do at room temperature is good.
3. Fast charging: Today's hottest fast chargers actually do some damage to battery life. The high voltage program can't prevent the charging battery temperature from rising, causing side effects inside the battery; the high current program is more likely to cause the SEI film on the negative side of the battery to rupture to a certain extent, and the electrolyte reaction, affecting the battery's lifespan.
Lithium Ion Battery Maintenance and Proper Use
1, lithium-ion batteries have a lifespan
We all know that lithium-ion batteries have a limited number of charge times, but at the same time, lithium-ion batteries are also like anything else, the battery also has a lifespan. So the next time you are going to buy a battery, remember to look at the date of manufacture of the lithium ion battery. The newer this is, the better, of course. Because your lithium ion battery is "dead" from the moment it leaves the factory. The lifespan of a lithium-ion battery depends on a number of factors. The best case scenario is that your Li-Ion battery will lose 20% of its maximum charge in a year, from the moment it leaves the factory.
2. Don't let your device run out of juice
Perhaps you've wondered why your cell phone, PDA, or iPod lights up the LCD screen when it's about to run out of juice, happily telling you, "Your battery is exhausted," and then shuts down automatically. The reason for this is simple: the cell phone has an internal circuit that automatically shuts down when the battery is too low. This circuit is set up to protect the phone. You can understand it this way: if your lithium-ion battery is too low, this can permanently damage your lithium-ion battery. So you can just plug it in and charge it at your convenience whenever possible.
Remember that a "one-off" charge cycle means that if you use 50% of your battery on the first day, charge it at night, and then use 50% the next day, that's a one-off cycle. That's one cycle.
Repeatedly charging a lithium-ion battery over and over again will not reduce battery life.
3, to prevent the battery temperature is too high
Lithium-ion battery charging will not be overcharged, it has internal circuit protection, lithium-ion batteries are most afraid of the problem of high temperatures, more than 40 degrees will reduce the lithium-ion batteries can be charged into the power.
How to extend the life of a new cell phone battery
The ultimate goal of cell phone battery maintenance is to extend the life of the cell phone battery, so that the cell phone battery can serve us for a longer period of time after a single charge.
1, the new purchase of cell phone charging need to pay attention to
The new purchase of cell phone batteries are the use of lithium-ion batteries, and the manufacturer has been activated to deal with the new cell phone batteries, each new phone battery will have a surplus of electricity, so the new purchase of cell phones for the first three to five charging as a period of adjustment, pay attention to each charging should be maintained in more than 14 hours, to ensure that fully activated!
2, lithium batteries do not need to be discharged, try to slow down the charge
Many friends think that cell phone batteries should be discharged before charging, this is not true, lithium batteries do not need to be discharged.
In addition, it is recommended that when charging, try to charge in a slow charging mode to minimize the wear and tear on your phone's battery. Note: No matter slow charging or fast charging, it can't last more than 24 hours, otherwise it will burn out the battery cell due to the huge electron current generated by the long time power supply.
3. Don't disconnect immediately after charging
When charging a cell phone battery, if the phone or charger shows that it is fully charged, don't disconnect it immediately, because the cell phone battery power is actually only 90% charged at this time, and you should give the battery a period of time to replenish the battery, and then use it again after the battery is fully charged, or else it will shorten the time of use.
4. Try not to turn on your phone while it's charging
If your phone is still on when you're charging, the battery will be discharged outward due to the phone's 'use', and inward due to the battery's charging, which is likely to cause voltage disruption and lead to the phone's circuit boards heating up, which can generate an instantaneous return current if there's an incoming call and cause damage to the phone's internal components. This means that you will not need to worry about the quality of the product to be able to meet your specific needs.
5. Charge the battery when it runs out
The number of times a cell phone battery is charged determines the battery's lifespan. Usually, lithium batteries can be charged/discharged about 500 times in a row, after which the performance of the battery will be greatly diminished. Therefore, it is recommended that you try to recharge your phone after the battery is exhausted or turns off automatically.
6, pay attention to the protection of cell phone battery
To cell phone battery maintenance in place, at the same time should also pay attention to the protection of cell phone battery, therefore, do not expose the battery in the high temperature or cold, like the three days of the day, should not be placed in the sun under the cell phone, through the exposure of the scorching sun; or get the air-conditioned room, placed in the cold air blowing place. When charging, it is normal for the battery to be a little warmer as the current draws back.
7, long unused need to activate
Such as cell phone batteries for a long time, the use of the time should be the first to the specialized cell phone repair point on the battery to carry out an activation process, but also their own use of a DC voltage regulator, adjusting the voltage to 5 ~ 6V, the current 500 ~ 600mA reverse connection to the battery. Note that a touch of release, repeat up to three times can be, after this treatment, and then use the original charger for the "adjustment period" charging.
8, charging time is not the longer the better
When charging a cell phone, it is important to note that not the longer the charging time is the better, there is no protection circuitry or non-genuine batteries should be full of power immediately after the power, otherwise it will be due to the heat or overheating affect the performance.
The battery's power divided by the output current of the charger can be, for example: a battery with a power of 800MAH, for example, the output current of the charger is 500MA Then the charging time is equal to 800MAH/500MA = 1,6 hours, of course, this is only the theoretical full charge of time calculations, when the charger shows that the charging is complete, it is best to give the battery about half an hour or so to replenish power. When the charger shows that the charging is finished, it is better to give the battery about half an hour of replenishment time. The lithium-ion battery must use a dedicated charger, otherwise it may not reach saturation state, affecting its performance.
9. A complete charge/discharge cycle for new batteries
After a long period of time, the metal contacts will oxidize, causing the phone to shut down or disconnect automatically during a call. This can be achieved by using a small cotton swab or toothpick wrapped in a hand towel and dipped in a little bit of alcohol. Do not use hard objects to scrape, that will aggravate the poor contact. If you don't have alcohol, you can use white wine instead. Use paper towel to dry immediately after wiping, so as not to spill the alcohol and cause short circuit between the two poles of the battery. A new battery can be fully charged and discharged 3-5 times before its internal chemicals are fully activated for optimal performance.
10. Use the original cell phone manufacturer's battery
Remind users to try to use the original cell phone manufacturer's battery and charger, or use regular products, and don't buy cell phone batteries and chargers from street vendors or unreliable places.
