How to use lithium batteries?

Lithium battery voltage and current is elusive to many people about the newly bought lithium battery. I saw that some senior players summarized the use of lithium battery and shared it with you, hoping to help. 1. How to use the newly purchased lithium battery? Should it be charged or discharged first? How to charge and discharge? First discharge with a small current (usually set to 1-2A), and then use 1A current for charge and discharge cycles 2-3 times , The battery has been activated 2. The new battery has just started to use, and the voltage is unbalanced. After charging and discharging several times, it is normal again. What is the problem? It is important because the individual batteries in the battery pack are matched, but there will still be There are individual differences in self-discharge. Generally, it will take more than 3 months for a new battery to pass from the factory to the user. During this time, the individual cells will exhibit different voltages due to the difference in self-discharge, and thus the battery pack The voltage difference in the battery becomes larger (that is, unbalanced); because the current chargers on the market all have a charge balance function, so the general unbalance will be repaired by the charger when charging 3. What kind of environment should the lithium battery be stored in? ? Store in a cool and dry environment, room temperature 15-35 ℃, ambient humidity 65% u200bu200b4. How long does lithium power use? How many cycles can be used normally? What factors affect the life? Air model lithium batteries can generally be used about 100 times. Important factors affecting life: 1. Temperature, the battery cannot be used or stored in an overheated environment (35℃); 2. Charge and discharge, the battery pack cannot be overcharged and discharged, and the voltage of a single cell must be 4.2-3.0V. In the meantime, the high-current working recovery voltage should be guaranteed to be above 3.4V; 3. Choose a model with suitable power to prevent the battery pack from being used under overload. 5. Should the new lithium battery be activated? Will it be affected if it is not activated? Impact? To activate, the new battery will usually take more than 3 months from the factory to the user. The battery will be in a dormant state. It is not suitable to perform high-intensity discharge immediately, otherwise it will be 6. The new battery will not be charged. What is the reason? The battery cell has zero power, the battery has a large internal resistance, and the charger mode is incorrect. 7. What does the C number of the lithium battery represent? C is the symbol of the battery capacity, which has the same meaning as the current symbol I. The C number represents us The often said rate is the abbreviation of the current size that the battery can work on the basis of the nominal capacity. Take 2200mAh20C as an example, 20C indicates the current that the battery can work normally 2200mA×20u003d44000mA; 20C discharge means 44000mA current pair Battery discharge statement: Some pictures and content of the articles published on this site are from the Internet.
