Battery dormancy is usually caused by over-discharge. In this case, it is best to activate it with low current and then charge it with normal current. Charge with a charger that is slightly higher than the normal phone charging voltage for strong activation and repair to wake up the Li-ion battery that is dormant and protected by excessive self-discharge.
What is battery hibernation?
The main body of battery hibernation is the unused lithium battery, characterized by a gradual drop in voltage. For a long time for various reasons do not use the lithium battery, due to self-discharge its voltage will gradually decline, when the voltage is lower than the minimum threshold voltage set by the lithium protection board, it will automatically cut off the power output. At this time, a multimeter outside the lithium battery is not measured voltage, with cell phones, universal charger can not be charged, which is called battery hibernation.
For a long time for a variety of reasons have not been used for a long time lithium battery, at this time with a multimeter in the lithium battery is not measured outside the voltage, with cell phones, universal charger can not be charged. Many people may think that the battery is bad, in fact, the battery may not be damaged at this time, it may just enter the hibernation mode.
How to activate the lithium battery hibernation?
Some friends in the use of cell phones, due to some bad habits, such as in the case of low battery charging while playing hand games, resulting in the phone completely depleted, often leading to their cell phone battery into hibernation, after which it will not charge into. The following Cunningham Electric lithium battery manufacturers give several solutions.
① Use direct power charging
The phone does not power off automatically after the phone can not be turned on, this time do not be anxious, the phone is not actually bad just because the power has run off so can not open. This time to replenish the power can be, I recommend using direct power charging, rather than using the computer jack and mobile power, the latter two charging speed is very slow.
②Charge after reinserting the battery
Smartphone automatically shut down after the power can not be turned on, first in a more suitable environment charging, too cold environment is easy to charge, and then disassemble the lithium battery reinserted, sometimes this method is still quite effective, the charging lamp lights up when the charge has begun to charge, patiently wait for a period of time to turn on the phone.
③ use universal charger charging
Put the dead phone on the power supply charging, do not rush to turn on the phone. Because the power is also needed to turn on the power, if charging or no effect, then you can use the universal charger to charge the phone battery. It only takes a while for the phone's lithium battery to be reactivated, and then it's time to switch back to the original charging method.
④Charge for a period of time and then turn on the phone
No matter which way to activate the dormant lithium battery, you can not rush to turn on the phone. Even if the battery is barely charged, it will soon be discharged when it is turned on again. It is recommended that after half an hour of charging, then turn the phone into flight mode.
The above is the lithium battery hibernation activation method. In the use of lithium batteries should be noted that the battery is placed in a period of time into a dormant state, when the capacity is lower than normal, the use of time is shortened. But lithium batteries are easy to activate, as long as the normal charge and discharge cycle after 3-5 times can activate the battery, restore the normal capacity.
