Know about mobile phone battery charging and maintenance knowledge

1. How to charge a new battery When using a lithium battery, it should be noted that the battery will enter a dormant state after being left for a period of time. At this time, the capacity is lower than the normal value, and the use time is also shortened. But the lithium battery is easy to activate, it only needs 35 normal charge and discharge cycles to activate the battery and recover the normal capacity. ) Due to the characteristics of the lithium battery, it is determined that it has almost no recall effect. From the beginning, it is best to choose the standard method of charging, which is a natural activation method. Regarding the activation of lithium batteries, the most widespread argument is that the charging time must exceed 12 hours and repeat three times to activate the battery. In fact, this is a misunderstanding, which is clearly a continuation of the Ni-Cd battery. Long-term overshoot can cause great damage to lithium batteries. Therefore, it is best to charge in accordance with the standard time and method, especially not to carry out an ultra-long charge that exceeds 12 hours. Generally, the charging method analyzed in the mobile phone manual is the standard charging method suitable for the mobile phone. 2. Does the lithium battery require trickle-charge lithium battery mobile phones or chargers will automatically stop charging after the battery overflows, there is no such thing as a nickel-electric charger that continues for 10 hours of trickle charging. In other words, if the lithium battery continues to be placed on the charger after overflowing, the so-called trickle charge will not be performed. In addition, on some mobile phones, after charging beyond a certain time, if the charger is not removed, the system will not only stop charging at this time, but will also begin to discharge to the charging cycle. This is the mobile phone manufacturer's self-maintenance settings for lithium batteries. It’s also worth noting that lithium batteries are also not suitable for overdischarge. Overdischarge poses a serious danger to lithium batteries, which may cause permanent loss of the battery. The most serious may be that the operation cannot be started normally, so when we use it, When you see the battery alarm, you must charge it. 3. Reasonable grasp of charging opportunities As mentioned above, lithium batteries have almost no recall function, but they are still limited by the number of recharges. Generally speaking, the cycle life of most lithium batteries is about 1000 times, so many people are committed to It is completely unscientific to use the battery of the mobile phone until it is automatically shut down. The criterion for recharging when the remaining battery power is used up is not to tell you to stop using the battery until it is completely discharged. The same as long charging, a widely spread saying is to use up the battery of the mobile phone as much as possible, and it is best to use active shutdown. This approach is actually only done on nickel batteries, with the intention to guard against recall effects. Unfortunately, it is also spread on lithium batteries today. Once there was a warning that the battery of the mobile phone was too low, but still did not continue to use it, such as the active shutdown that has always been used. As a result, the mobile phone in this example showed no response during subsequent charging and booting, and had to be sent to customer service for overhaul. In fact, this is caused by the battery's over-discharge, which causes the voltage to be too low, so that it does not have normal charging and starting conditions.
