10 teaches you how to use the newly purchased lithium battery

Many people are elusive about the newly purchased lithium battery. I have seen some experienced players summarize the use of lithium batteries, and share with you, I hope to bring help.

1. How to use the newly purchased lithium battery? Is it charging or discharging first? How to charge and discharge? First discharge a small current (generally set to 1-2A), then use the current of 1A for charge and discharge cycle 2-3 times, the battery has been activated

2. The new battery just started to use, the voltage is unbalanced, after charging and discharging a few times, it is normal, what is the problem? Mainly because the individual cells in the battery pack are paired well, but there will still be different individual differences in self-discharge. The new battery will generally be more than 3 months from the factory to the user. During this time, The single cell will exhibit different voltages due to the difference in self-discharge, so the voltage difference in the battery pack becomes larger (unbalanced); since the chargers on the market currently, have the charging balance function, the general does not Balance will be fixed when charging by a charger

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

4. How long does lithium power use? How many cycles can you normally use? What is the life factor affected? The model lithium battery can generally be used about 100 times, the main factors affecting life: 1. Temperature, the battery cannot be used or stored in an overheated environment (35 ° C); 2. Charge and discharge, battery pack charging and discharging cannot be excessive, must guarantee The voltage of the battery should be between 4.2-3.0V, and the high-current working recovery voltage should be above 3.4V. 3. Select the appropriate power model to avoid the battery pack being used under overload conditions.

5. Does the new lithium battery need to be activated? Will it be affected if it is not activated? Need to activate, the new battery from the factory to the user, usually there will be more than 3 months, the battery will be in a dormant state, it is not suitable for high-intensity discharge immediately, otherwise, it will affect the battery efficiency and life.

6. The new battery, what is the reason for not charging? The battery core is zero, the battery has large internal resistance, and the charger mode is incorrect.

7. What does the C number of a lithium battery stand for? "C" is the symbol of the battery capacity, which is the same meaning as the sign of the current is "I". The "C number" represents the magnification we often say, that is, the abbreviation of the current that the battery can work on the basis of the nominal capacity. 2200mAh20C as an example, 20C identifies that the battery can work normally at 2200mA × 20 = 44000mA; 20C discharge uses 44000mA current to discharge the battery.

8. What is the optimal storage voltage for lithium? What is the normal battery charge? The single voltage is between 3.70-3.90V, usually with 30-60% power

9. How much pressure difference between the battery cells and the battery cells is normal? What should I do if I exceed the rated differential pressure? It is normal for a new battery with a factory date of 1 month to be around 30mV or 0.03V. A battery pack that has been placed for a long time is more than 3 months old. It can be used at 100mV or 0.1V. The battery pack exceeds the rated differential pressure. A small current (1A) charge and discharge cycle of 2-3 times can be performed with a smart charger with balance function, which can repair most battery packs with abnormal pressure difference.

10. Can the battery be stored for a long time after it is fully charged? The storage time of full power can't exceed 7 days; the battery is best stored under a single voltage of 3.70-3.90, which is beneficial to extend battery life. If it is not used for a long time, ensure that it is charged and discharged every 1-2 months.
