Top 10 questions about the use of common lithium batteries

10 questions for ordinary lithium batteries 1. How does the newly purchased lithium battery work? Charge or discharge first? How do I charge? The factory has been activated, and the battery is charged first and used normally. 2. The new battery has just started to be used, and the voltage is not balanced. After several times, it is normal again. What kinds of problems? The important reason is that although the batteries in the personal battery pack are well matched, 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. The single battery will be different during this time, because the self-discharge shows different voltages, and the voltage difference of the battery is large (i.e., unbalanced); because The chargers on the market now have a charge balance function, so the general imbalance will be repaired by the charger. 3. In what environment should lithium batteries be stored? Store in a cool and dry environment, room temperature 15-35℃, ambient humidity 65% u200bu200b4. How long does the lithium battery last? How many cycles can you usually use? What factors affect the lifespan? Model Lithium batteries can generally be used for about 100 times. The important factors affecting the life are: 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, and the voltage of a single battery should be between 4.2v and 3.0v. 3. Choose a model with appropriate power to prevent the battery from being forced to use under overload conditions. 5. Do you want to activate the new lithium battery? Will it affect if you do not activate it? Do not activate, the new battery will usually take more than 3 months from the factory to the user's hands, the battery will be in a dormant state, not suitable for immediate Carry out high-intensity discharge, otherwise it will affect the efficiency and life of the battery. 6. What is the reason for charging a new battery? The battery is zero, the battery resistance is large, and the charger mode is incorrect. 7. What does the C number of lithium batteries represent? C is a symbol of battery capacity, and the current symbol is the same as me. C represents a multiplier. We often say that the battery can work on the basis of rated capacity. The current abbreviation, taking 2200mah20c as an example, 20C determines that a battery with a current of 2200 mA can work normally × 20 u003d 44000 horses; 20C discharge refers to discharging the battery with a current of 44000 mA. 8. What is the optimal storage voltage of lithium batteries? What is the average price of the factory batteries? The single voltage is between 3.70~3.90V, and the factory will generally take 30-60% of the electricity 9. The normal pressure difference between individual batteries What is it? What if the rated pressure difference is exceeded? It is normal for a new battery to be processed at 30mv and about 0.03V within one month. If the battery is longer than three months, you can use a battery with a rated pressure difference of 100mv or more than 0.1V. The low current charge and discharge cycle (1) of 2 to 3 times that of the smart charger for balancing function can repair the voltage difference of most battery packs. 10. Can the battery be stored for a long time after it is fully charged? The full storage time of the battery should not exceed 7 days; the battery is best stored in a separate voltage state of 3.70-3.90, which is beneficial to extend the battery life. If it is not used for a long time, it should be charged and discharged every 1-2 months. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
