10 Common Questions About The Use Of Lithium Batteries

1. How to use the newly purchased lithium battery? Is it charging or discharging first? How to charge and discharge?
It is activated from the factory, and the battery is charged first and can be used normally.

2. The new battery has just started to be used, the voltage is unbalanced, and after a few times of charging and putting, it is normal again, what is the problem?
Mainly because although the individual cells in the battery pack are paired, there will still be individual differences in self-discharge, and the new battery will generally have more than 3 months from the factory to the user's hands. Because all chargers on the market currently have a charge balancing function, the general imbalance will be repaired by the charger when charging.

3. What kind of environment should lithium batteries be stored in?
Store in a cool and dry environment, room temperature 15-35°C, ambient humidity 65%

4. How long can lithium batteries last? How many cycles can be used normally? What factors affect lifespan?
Model lithium batteries can generally be used about 100 times, the main factors affecting the lifespan:
1). Temperature, the battery cannot be used or stored in an overheated environment (35°C);
2). Charging and discharging, the charging and discharging of the battery pack should not be excessive, the voltage of a single cell must be between 3). 2-3.0V, and the high-current working rebound voltage should be guaranteed to be above 3.4V;
4). Choose a model with appropriate power to avoid the battery pack being reluctantly used under overload.

5. Does the new lithium battery need to be activated? Will it affect if I don't activate it?
No need to activate, the new battery from the factory to the user, generally more than 3 months, the battery will be in a dormant state, it is not suitable to do high-intensity discharge immediately, otherwise it should affect the efficiency and life of the battery.

6. What is the reason for the new battery that cannot be charged?
The battery cell has zero battery, the battery has large internal resistance, and the charger mode is wrong.

7. What does the C number of lithium batteries represent?
"C" is the symbol of battery capacity, and the symbol of current is "I" is the same meaning, "C number" represents the rate we often say, that is, the abbreviation of the current size of the battery can work on the basis of nominal capacity, taking 2200mAh20C as an example, 20C indicates that the battery can work normally current 2200mA×20=44000mA; 20C discharge is to discharge the battery with a current of 44000mA.

8. What is the optimal storage voltage for lithium batteries? What is the typical battery charge from the factory?
The voltage of a single unit is between 3.70-3.90V, and it will generally come with 30-60% of the power from the factory

9. How much voltage difference between a single cell of a battery pack is considered normal? What should I do if I exceed the rated pressure difference?
New batteries with a factory date of 1 month are generally normal at 30mV, that is, about 0.03V, and battery packs that have been placed for a long time for more than 3 months, can be used at 100mV, that is, 0.1V, and battery packs that exceed the rated voltage difference can be used with a smart charger with balancing function to carry out 2-3 small current (1A) charge and discharge cycles, which can repair most battery packs with abnormal voltage.

10. Can the battery be stored for a long time after being fully charged?

The storage time on a full charge cannot exceed 7 days; It is best to store the battery in a single 3.70-3.90 voltage state, which is conducive to extending the battery life, and if it is not used for a long time, ensure that it is charged and discharged every 1-2 months.
