What are the characteristics of 18650 lithium batteries

The voltage is relatively high, not only can support 3.6V, but also support 3.8V and 4.2V, so it will be much higher than other batteries, we must know that Ni-Cd and Ni-MH batteries can The voltage used is only 1.2V. 2. Compared with other batteries, the capacity of large-capacity lithium battery has also been greatly improved. Normally, it is between 1200mah and 3600mah, but if it is a normal battery, it is only about 800mah. If we use lithium battery If used in combination, it will be even higher, and it can easily exceed 5000mah. 3. Long life. The service life of this kind of battery is very long. If we use it normally all the time, the service life is very high. Generally, it can reach more than 500 times, which is more than twice that of ordinary batteries. . 4. High safety performance The safety of lithium batteries appearing on the domestic 18650 lithium battery rankings is very high, there will be no explosion or combustion, and they are very green, safe, non-toxic, and pollution-free. It can be said that the safety in all aspects has been achieved, and the high temperature resistance is also very good, even at a high temperature of 65 degrees, it can achieve a high discharge efficiency. In order to guard against the battery short-circuit phenomenon, the positive and negative electrodes of the battery are separated. Therefore, there is basically no short-circuit situation. We can also install a protective board when using it. In this way, we can be guarded to a large extent. The battery is overcharged and overdischarged, so that our battery has a longer battery life. Service life. 6. Small internal resistance. The internal resistance of this battery is much smaller than that of other liquid batteries. The internal resistance of domestic polymer batteries can even be less than 35m. In this way, the battery is basically not in use. There will be self-consumption, extending the standby time of the mobile phone. From this point of view, it can be in line with international standards, so this kind of lithium battery is a good ideal choice. 5. No memory effect Lithium batteries do not have any memory effect, so they are more convenient in daily use. It is important because if there is no memory effect, we don't need to empty the remaining power before charging. 8. Wide range of use Lithium batteries can be used in a very wide range, not only for laptops, walkie-talkies, portable DVDs and other equipment, but also for airplanes, toys, cameras and other products.
