What is battery hibernation? How to activate lithium battery sleep? Battery sleep is usually caused by over-discharge. At this time, it is best to activate with a small current and then charge with a normal current. Use a charger that is slightly higher than the normal mobile phone charging voltage to charge, perform strong activation, and repair the lithium battery that wakes up due to excessive self-discharge and dormant protection.
What is battery hibernation?
The main body of the battery sleep is an unused lithium battery, which is characterized by a gradual decrease in voltage. For lithium batteries that have not been used for various reasons for a long time, their voltage will gradually drop due to self-discharge. When the voltage is lower than the minimum threshold voltage set by the lithium battery protection board, the power output will be automatically cut off. At this time, the voltage cannot be measured outside the lithium battery with a multimeter, and it cannot be charged with a mobile phone or universal charger. This is called battery dormancy.
For a lithium battery that has not been used for a long time due to various reasons, the voltage cannot be measured outside the lithium battery with a multimeter at this time, and it cannot be charged with a mobile phone or a universal charger. Many people may think that the battery is broken. In fact, the battery may not be damaged at this time, it may just enter the sleep mode.
How to activate lithium battery sleep?
When some friends are using the mobile phone, due to some bad habits, such as playing mobile games while charging under low battery conditions, the battery of the mobile phone is completely exhausted, often causing their mobile phone battery to go to sleep and then fail to charge. The following lithium battery manufacturers provide several solutions.
①Charge using direct power supply
The phone cannot be turned on after it is powered off automatically. Don't worry at this time. The phone is actually not broken, but it can't be turned on because the battery has run away. At this time, it is enough to recharge the battery. The editor recommends to use a direct power supply instead of a computer socket and a mobile power supply. The charging speed of the latter two is very slow.
②Charge after reinserting the battery
When the smart phone automatically shuts down after no electricity and cannot be turned on, first charge it in a more suitable environment. If it is too cold, it will not be able to charge. Then remove the lithium battery and reinsert it. Sometimes this method works well. Charging When the light is on, it means that it has started charging, and you can start it up after waiting patiently for a period of time.
③Using the universal seat to charge
Put the dead cell phone on the power supply to charge, don't turn it on in a hurry. Because power is also needed to turn on, if charging is still ineffective, you can use a universal charger to charge the phone battery. It only takes a period of time for the mobile phone's lithium battery to be reactivated. At this time, it is enough to change back to the original charging method.
④Charge for a while and then turn it on
No matter which method is used to activate the dormant lithium battery, you can't turn it on in a hurry. A certain amount of power is required to turn on the battery, even if the battery is barely charged, it will soon be discharged when the device is turned on again. It is recommended to turn on the phone after half an hour of charging, and then set the phone to airplane mode.
The above is the activation method of lithium battery sleep. In the use of lithium batteries, it should be noted that after the battery is left for a period of time, it will enter the dormant state. 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, as long as 3-5 normal charge and discharge cycles can activate the battery and restore normal capacity.
