Advantages of 18650 lithium battery
1. Large capacity: The capacity of 18650 lithium battery is generally between 1200mah and 3600mah, while the general battery capacity is only about 800mah. If combined into a 18650 lithium battery pack, the 18650 lithium battery pack can easily exceed 5000mah.
2. Long life: The 18650 lithium battery has a long life, and the cycle life can reach more than 500 times in normal use, which is more than twice that of ordinary batteries.
3. High safety performance: 18650 lithium battery has high safety performance. In order to prevent battery short-circuit phenomenon, the positive and negative electrodes of 18650 lithium battery are separated. Therefore, the short-circuit phenomenon may have been reduced to the extreme. A protection board can be installed to avoid overcharge and overdischarge of the battery, which can also extend the service life of the battery.
4. High voltage: The voltage of 18650 lithium battery is generally 3.6V, 3.8V and 4.2V, which is much higher than the 1.2V voltage of nickel-cadmium and nickel-hydrogen batteries.
5. No memory effect: It is not necessary to empty the remaining power before charging, which is convenient to use.
6. 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. In time, it can fully meet the international standards. This kind of polymer lithium battery that supports large discharge current is an ideal choice for remote control models, and it has become the most promising product to replace Ni-MH batteries.
7. It can be combined in series or parallel to form a 18650 lithium battery pack.
8. Wide range of use: notebook computers, walkie-talkies, portable DVDs, instrumentation, audio equipment, model airplanes, toys, camcorders, digital cameras and other electronic equipment.
