Summary of how to use lithium-ion batteries

Many people are skeptical about newly purchased lithium batteries. I saw a veteran sum up the use of lithium batteries and shared it with you, hoping to help everyone.

1. How to use the new lithium battery? First charge or discharge first? How do you charge? First discharge with a small current (usually set to 1-2A), then use 1A current to charge and discharge 2-3 times to activate the battery.

2. The new battery has just started to use, the voltage is unbalanced, charge it several times, and then return to normal, what’s the problem? Matching is very important, because the battery of a single battery is good, but there are still individual differences in self-discharge. It usually takes more than 3 months for the battery to go from the factory to the user. During this time, the single battery will display due to different self-discharge voltages. Since all chargers on the market have a charge balance function, the general imbalance will be during charging. Be corrected.

3. What kind of environment should lithium batteries be stored in? Stored in a cool and dry environment, room temperature 15-35℃, environmental humidity 65%

4. How long can a lithium battery last? How many cycles can you usually use? What factors affect the lifespan? Air-type lithium batteries can be used for about 100 times. The important factors that affect their service life are: 1. When the temperature is too high, the battery cannot be used or stored in an environment where the temperature is too high (35°C). The battery pack cannot be overcharged or overdischarged during the charging and discharging process. 2. The voltage of a single cell battery is 4.2-3.0V, and the high-current recovery voltage is above 3.4V; choose a model with appropriate power to prevent the battery pack from being forced to use under overload conditions.

5. Is the demand for new lithium activated? Will it be effective if it is deactivated? When the demand is activated, it will take more than 3 months for the new battery to be delivered from the factory to the user. The battery will be in a dormant state and is not suitable for immediate high-intensity discharge. Otherwise it will affect the battery power and life.

6. What is the reason why the new battery cannot be charged? The battery is zero, the battery resistance, and the charger mode is wrong.

7. What is the C number of lithium batteries? C is the symbol of battery capacity, and the symbol of current is the same as I mean. C represents the multiplier effect we often say, that is, the rated capacity of the battery can be abbreviated according to the current , For example, 2200mah20C, 20C means that the battery’s normal operating current is 2200ma × 20=44000 mA;

8. What is the best storage voltage for lithium? How much electricity can this battery hold? The single voltage is between 3.70~3.90V, and the general factory electricity accounts for 30%~60%.

9. What is the normal pressure difference between the batteries? If I exceed the pressure difference rating, what should I do? It is normal for a new battery to be about 30 mV within one month from the date of production and 0.03 V. Put the battery out 3 For more than a month, 0.1 V can be used at 100 mV for a long time. The battery pack that exceeds the rated pressure can be used to balance 2 to 3 times the low current charge and discharge cycle (1 time) with the function of the smart charger to correct the abnormal pressure of most battery packs. Difference.

10. Can the battery be stored for a long time after it is fully charged? The storage time should not exceed 7 days; it is best that the battery is only in the voltage state of 3.70-3.90, which is conducive to prolonging the battery life. If it is not used for a long time, make sure to charge it every 1-2 months Discharge once.
