1. Wide range of applications
Notebook computers, walkie-talkies, portable DVDs, instrumentation, audio equipment, model airplanes, toys, camcorders, digital cameras and other electronic equipment.
2, series connection
can be combined in series or parallel to form a 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 battery’s self-consumption and extends the standby time of the mobile phone. The level of world integration. 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 commodity to replace nickel-hydrogen batteries.

4, no memory effect
There is no need to empty the remaining battery before charging, which is convenient to use.
5, high voltage
The voltage of 18650 lithium battery is usually 3.6V, 3.8V and 4.2V, which is much higher than the 1.2V voltage of nickel-cadmium and nickel-hydrogen batteries.
6, high safety function
18650 lithium battery has high safety functions, no explosion, no incineration; non-toxic, non-polluting, and has passed RoHS trademark certification; various safety functions are completed in one go, and the number of cycles is greater than 500; the high temperature resistance function is good, and the discharge efficiency is 100% under the condition of 65 degrees. . In order to prevent the battery from short-circuiting, the positive and negative electrodes of the 18650 lithium battery are separated. So the short-circuit phenomenon may have been reduced to the extreme. A protective board can be installed to prevent overcharge and overdischarge of the battery, which can extend the service life of the battery.
7, long service life
The service life of 18650 lithium battery is very long, the cycle life can reach more than 500 times in normal use, which is more than twice that of ordinary batteries.
8. Dako nga kapasidad
The capacity of 18650 lithium battery is usually between 1200mah~3600mah, and the battery capacity is usually only about 800. If 18650 lithium batteries are combined to form a 18650 lithium battery pack, the 18650 lithium battery pack can break 5000mah in a so-so.
