Brief introduction to 18650 lithium ion battery capacity and advantages

18650 lithium ion battery capacity It is worth noting that many buyers in the city have a misunderstanding that if the capacity is high, the actual discharge current will be large, but this is just the opposite: 18650 lithium ion batteries are generally divided into capacity type and rate type, and capacity type is important. A large capacity appears, but the discharge current is generally lower than 1C, and the current is small; the rate type can be discharged with large current, but the capacity is lower and the use time is not long. This is similar to fish and bear's paw. Most of the application scales have different current and time requirements, so most of the power supply batteries appear as battery packs. When choosing a battery pack, you should consider the consistency, immutability, and safety of the battery. Each battery in the core must be matched with various values, such as voltage communication, internal resistance communication, and capacity communication. These indicators are very important. The value of 18650 lithium-ion batteries is proportional to the size of the capacity. The larger the capacity, the greater the energy ratio, and the more raw materials used, so the value will be more expensive. The general value is 10-30 yuan/piece. How to understand the actual capacity of the 18650 lithium-ion battery? The labeled capacity of unscrupulous manufacturers, but you can’t believe it. If you want to know the actual capacity, you have to conduct a charge and discharge test through professional testing and testing equipment. Therefore, most people don’t know the detailed capacity size, and it is easy to be deceived by the seller. Buyers really think that there is something wrong with the capacity, and they can ask the supplier to issue a test report or choose a third-party professional test agency to report. Advantages of 18650 lithium-ion battery 1. Large capacity. The capacity of 18650 lithium-ion battery is generally between 1200mah~3600mah, and the general battery capacity is only about 800mah. If combined into a 18650 lithium-ion battery pack, the 18650 lithium-ion battery pack can easily break 5000mah. 2. Long life. 3. High serene function. 18650 lithium ion battery has high safety function, non-explosive, non-combustible; non-toxic, non-polluting, and RoHS trademark certification; various safety functions can strike iron while hot, and the number of cycles is more than 500; high temperature resistance performance, discharge efficiency at 65 degrees 100%. In order to prevent the battery short-circuit phenomenon, the positive and negative electrodes of the 18650 lithium-ion battery are separated. Therefore, the short-circuit phenomenon has probably been reduced to the extreme. A protective board can be installed to prevent overcharge and overdischarge of the battery, which can also delay the service life of the battery. 4. High voltage. The voltages of 18650 lithium-ion batteries are generally 3.6V, 3.8V and 4.2V, which are much higher than the 1.2V voltages of nickel-cadmium and nickel-hydrogen batteries. 5. There is no image effect. It is not necessary to empty the remaining power before charging, which is convenient to use. 6. Small internal resistance. 7. It can be combined in series or parallel to form 18650 lithium ion battery. Statement: Some pictures and content of articles published on this site are from the Internet.
