Summarize the use of lithium batteries

The new type of lithium battery is elusive? The veteran teaches many people about the uncertainty of the newly purchased lithium battery. The author saw a veteran player summarize the use of lithium batteries and share with you, hoping to help everyone. 1. How to use a new lithium battery? Charge or discharge first? How to 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, and after a few recharges, it returns to normal. What kinds of problems? The match is important because the battery of a single battery is good, but there are still individual differences in self-discharge. From the factory to the user, there is usually more than 3 months. During this time, the single battery will display the voltage difference of the battery pack (that is, larger, unbalanced) due to the different self-discharge voltage; because of the chargers on the market Both have a charge balance function, so when the charger is charging, the general imbalance will 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% u200bu200b4. How long can lithium batteries be used? How many cycles can you normally use? What factors affect Life? Air-type lithium batteries can generally 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 overheated environment (35℃); 2.2. When charging and discharging, the battery pack should not be overcharged and discharged. The voltage of a single battery is 4.2-3.0v, and the high-current recovery voltage is above 3.4v; 3. Choose a model with appropriate power to prevent the battery pack from being forced to use under overload conditions. 5. Has the demand for new lithium been activated? Will it be effective if it is not activated? When the demand is activated, the new battery will be in the hands of the user for more than 3 months, and the battery will be in a dormant state, which is not suitable Perform high-intensity discharge immediately, otherwise the power and life of the battery will be affected. 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 a lithium battery? C is a symbol of battery capacity, and the current symbol is the same as me. C represents the multiplier effect we often call, that is, based on the rated capacity of the battery The current size can be abbreviated, 2200mah20C as an example, 20C indicates that the battery can operate normally. The current is 2200mA×20u003d44000 horses; the battery is discharged at a current of 44000mA. 8. What is the best storage voltage for lithium? How much electricity can the battery hold? The single voltage is between 3.70~3.90V, and the general factory electricity accounts for 30%~60%. 9. How big is the pressure difference between the batteries is normal? If it exceeds the rated pressure difference, what should I do? 30mv about 0.03V within one month of the processing date of the new battery is normal, and it is normal for the battery to exceed 3 after being placed for a long time. For more than a month, 0.1V can be used at 100mv, which exceeds the rated pressure difference of the battery pack. It can be used for low-current charging and discharging cycles of 2 to 3 times that of the smart charger of the balancing function (1), correcting most abnormal pressure differentials Battery pack. 10. Can the battery be stored for a long time after it is fully charged? The storage time should not exceed 7 days; the battery should only be in the voltage state of 3.70-3.90, which is beneficial to prolong the battery life. If it is not used for a long time, it is guaranteed to be charged every 1-2 months Discharge once. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
