How to activate the sleep state of lithium-ion batteries? Activation method for lithium-ion batteries. After leaving the lithium-ion battery for a period of time, it enters a sleep state. At this time, the capacity is lower than the normal value, and the usage time is shortened accordingly. But lithium-ion batteries are easy to activate, as they can be activated after 3-5 normal charging and discharging cycles. Due to the inherent characteristics of lithium-ion batteries, they have almost no memory effect, so users should not use special methods or devices during the activation process of new lithium-ion batteries in their phones.

How to activate the sleep state of lithium-ion batteries

1. Use the original charging cable to connect to the power supply for charging, and do not use your phone during the charging process.

2. Use a low voltage charger to charge for 30 minutes to activate the battery, which can be charged using a computer USB and power bank.

3. You can try charging quickly for one to two hours and use a professional tester to check if there is an increase in voltage. If there is an increase, you can choose to continue charging with the original charger, which can activate the lithium-ion battery.

4. No matter which method is used to activate the dormant lithium-ion battery, you should not rush to turn it on. It is recommended to charge it for half an hour before turning it on, and then set the phone to airplane mode.

Activation methods for lithium-ion batteries

1. The activation of lithium-ion batteries should not be done in a special way, as they will naturally activate during normal use. If you insist on using the popular "first three 12 hour long charging activation" method, it will not actually be effective.

2. You can activate your phone's lithium-ion battery with an 18650 lithium-ion battery. The voltage of the 18650 lithium-ion battery should not be too high, ranging from 3.3 to 3.7V, otherwise the charging current of the lithium-ion battery will be too high

3. Using a mobile power source to connect the positive and negative poles of the battery with a few taps can also activate it. The time control should not be too long to activate it. After activation, there is voltage and it can be charged normally.

4. Discharge or resistance discharge can be used. When using discharge, it should be placed at a level where the machine starts and stops. Resistance discharge can be achieved by connecting a small electric ball with the corresponding voltage for a long time until the small electric ball is connected and immediately extinguishes.

5. Try charging quickly for one to two hours and use a professional tester to check if the voltage has increased. If there is an increase, you can choose to continue charging with the original charger to activate the battery.

Regarding lithium-ion batteries that have not been used for a long time, the voltage cannot be measured outside the lithium-ion battery using a multimeter, and it cannot be charged with a mobile phone or universal charger. Many people may think that the battery is broken, but in fact, the battery may not be damaged at this time, just entering sleep mode. Due to its own discharge, the voltage of lithium-ion batteries will gradually decrease. When the voltage is lower than the minimum threshold voltage set by the lithium-ion battery's protection board, the power output will be automatically cut off, and the lithium-ion battery will enter sleep mode.

In various fields of the national economy, lithium-ion batteries are widely used. Due to factors such as memory effects and increased internal resistance caused by unreasonable charging, discharging or maintenance during use and storage, the capacity and lifespan of lithium-ion batteries are greatly reduced, and even unusable phenomena often occur, which affects the performance of the equipment. Therefore, timely and necessary maintenance and upkeep of lithium-ion batteries are necessary. Activation is an important part of battery maintenance, which can improve the availability of lithium-ion battery packs and reduce damage to lithium-ion batteries.
