How to activate lithium batteries that have not been used for a long time:
1: Standard rechargeable batteries increase the operating voltage. First connect to any ordinary 12V rechargeable batteries, such as 48V/20A rechargeable batteries, then connect to a For 12V rechargeable battery series, the working voltage may be slightly increased or decreased to 13V, then connected to the main charging head for charging, and wait for the indicator light to turn to the green charging head. Once the stock rechargeable battery is removed, all regular batteries can be charged.
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 low-voltage rechargeable battery 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.
How to activate lithium battery in cell phone
Use a special lithium battery charger After the lithium battery is connected to the charger, the indicator light turns orange and begins to load. . When the lithium battery reaches full charge. When the battery is full, charging stops, the indicator turns orange and charging is complete.
What to note whene the use of lithium batteries:
The battery will enter a dormant state after being left for a period of 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 usedplaced on the charger.
On some machines, if the charger is not removed after charging for more than a certain time, the system will not only not stop charging, but will also start a discharge-charge cycle . This harms battery life.
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 canCannot be recharged at any time.
Today, they are all lithium batteries. For new devices, the first full charge is sufficient. There is no need to charge it for 12 hours each time for the first three times like other batteries. Before. You can just use it and charge it as you go. No deep activation is required. It will be better to pay attention to the following points.
1
, lithium-ionThe sub-battery has a lifespan. Lithium-ion batteries
are limited in the number of times they can be charged, but at the same time, lithium-ion batteries, like everything else, also have a limited lifespan

.
2. Do not let the device completely run out of power. If the lithium-ion battery charge is too low, it may permanently damage the lithium-ion battery. So you can plug it in and charge it whenever you want.suitable
as much as possible.
3. Lithium-ion batteries will not be overcharged and are protected by internal circuitry.
4. The biggest fear of lithium-ion batteries is the problem of excessive temperature.
Temperatures above 40 degrees will reduce the ability of lithium-ion batteries to be charged.
