1. How to properly activate the lithium-ion battery when it is not used for a long time? Typically, lithium-ion batteries are activated and pre-charged by the manufacturer before leaving the factory, so the batteries have residual power and can be used directly. When removing a battery that has not been used for a long time, first discharge the battery until the device automatically turns off, then fully charge it in the off state, then use- until it turns off automatically. This cycle will essentially return. the battery in the active state.
2. How to activate the lithium-ion battery correctly if it is not used for a long time?
①Lithium batteries need to be activated, but this is what the lithium battery factory should do, not what the user should do. Lithium batteries are easy to activate.After 3-5 normal charge and discharge cycles, the battery can be activated and restored to its normal capacity. The process of activating a lithium-ion battery that has not been used for a long time is as follows:
1: A newly used lithium-ion battery usually has of the remaining power, so do not charge it yet. Put the battery into the product and use it normally until the power is so low that it cannot be turned on at all.
2: For the first charge, it is better to use the original charger, and it is better to turn off the phone. Many people don't turn off the phone. charging for convenience, which is not conducive to activating the capacity of the lithium battery. And we remind everyone that it should be charged continuously for more than 12 hours and less than 15 hours. If it says it is fully charged, do not unplug itstep and let it charge!
3: After being fully charged for the first time, it cannot be turned on if used normally. You can press process 2 again to continue!
4: Fully discharge and fully charge (i.e. repeat process 2 and process 3) three times. At this time, the battery is successfully activated and can reach the best capacity state.

How to activate the lithium battery
Use a dedicated lithium battery charger and connect the battery lithium charging After turning on the device, the indicator light turns orange and charging begins. When the lithium battery reaches a full charge state, charging stops, the indicator light turns orange, and charging is completed.
Things to note when using lithium batteries:
The battery will enter a dormant state after being left forsome time. At this point, capacity is lower than normal. The value and duration of use are also shortened. However, lithium batteries are easy to activate. After 3-5 normal charge and discharge cycles, the battery can be activated and restored to its normal capacity.
New lithium batteries do not require special methods or equipment during the activation process. The “natural activation” charging method using standard methods is best.
:Dangers of long-term charging and deep charging:
Long-term charging can lead to overcharging. Lithium batteries or chargers will automatically shut off when the battery is fully charged. After the lithium battery is fully charged, it will be charged in vain when placed on the charger.
On some machines, if the charger is not removed after charging for more thans of a certain time, the system will not only not stop charging, but also start a discharge-charge cycle. Concerning battery life is disadvantageous.
Long-term charging takes a long time and usually needs to be done at night. In many places, voltage at night is relatively high and fluctuates considerably. Lithium batteries are poorly resistant to charge and discharge fluctuations.
Shallow discharge and surface charge are more beneficial for lithium batteries. Deep discharge and deep charge are only necessary when the product's power module is calibrated for lithium batteries. Therefore, products powered by lithium batteries do not necessarily have to follow the process. It's all about convenience and can be recharged at any time.
How to activate lithium batteries that have not beenused for a long time:
1: Rechargeable batteries in series increase the working voltage, first connect them to all ordinary 12V rechargeable batteries, such as 48V rechargeable battery/ 20A, then connect to a series of 12V rechargeable batteries, the working voltage can slightly rise and fall to 13V, then connect the main charging head to charge, wait for the charging head indicator light to turn to green, after the series rechargeable battery is removed, all ordinary batteries can all be recharged.
2: Parallel battery voltage conversion, a rechargeable battery in series is connected to a rechargeable battery of the same specification, such as a 48V/20A rechargeable battery, and a series connection is connected to a bank of normal rechargeable batteries. batteries. At this time, the operating voltage will flow into a battery rLow voltage e-charger to recharge the battery. After charging, the battery can be connected to the charging head.
3: Charging the low voltage battery. If the lithium-ion battery is not charged for a long time, it can first use a small low-voltage charging head to charge the battery slowly, such as 60V/20a rechargeable battery, then to 48v/20a to charge the small battery. It can also be charged.
