Uses and advantages of 18650 lithium battery

1. Wide range of use: notebook computers, walkie-talkies, portable DVDs, instrumentation, audio equipment, model airplanes, toys, camcorders, digital cameras and other electronic equipment. 2. Series can be combined in series or parallel to form 18650 lithium battery pack. 3. Small internal resistance. The internal resistance of polymer batteries is smaller than that of ordinary liquid batteries. The internal resistance of domestic polymer batteries can even be below 35mΩ, which greatly reduces the self-consumption of the battery and prolongs the standby time of the mobile phone. , Can reach the level of international standards. This kind of polymer lithium battery that supports large discharge current is an ideal choice for remote control models, and becomes the most promising product to replace nickel-hydrogen batteries. 4. There is no memory effect. It is not necessary to empty the remaining power before charging, which is convenient to use. 5. High voltage 18650 lithium battery voltage is generally 3.6V, 3.8V and 4.2V, much higher than the 1.2V voltage of nickel-cadmium and nickel-hydrogen batteries. 6. High safety performance 18650 lithium battery has high safety performance, non-explosive, non-combustible; non-toxic, non-polluting, and has passed RoHS trademark certification; various safety performances can be achieved in one go, and the number of cycles is greater than 500; high temperature resistance performance, under 65 degrees The discharge efficiency reaches 100%. In order to prevent the battery from short-circuiting, the positive and negative electrodes of the 18650 lithium battery are separated. Therefore, the short-circuit phenomenon may have been reduced to the extreme. A protective board can be installed to avoid overcharge and overdischarge of the battery, which can also extend the service life of the battery. 7. Long service life The 18650 lithium battery has a long service life. The cycle life can reach more than 500 times in normal use, which is more than twice that of ordinary batteries. 8. The capacity of 18650 lithium battery with large capacity is generally between 1200mah~3600mah, while the general battery capacity is only about 800. If 18650 lithium batteries are combined to form a 18650 lithium battery pack, the 18650 lithium battery pack can break through casually. 5000mah.
