Advantages of the 18650 lithium ion battery:
1, large capacity
The capacity of the 18650 lithium ion battery is generally between 1200mah and 3600mah, while the general battery capacity is only about 800. If combined into a 18650 lithium ion battery pack, the 18650 lithium ion battery pack can easily break through 5000mah.
2, long life
The 18650 lithium ion battery has a long service 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 security performance
The 18650 lithium ion battery has high safety performance, no explosion, no burning, non-toxic, non-polluting, RoHS-certified; all kinds of safety performance in one go, the number of cycles is more than 500 times; high temperature resistance is good, discharge efficiency is up to 100% under 65 degrees . In order to prevent battery short circuit, the positive and negative poles of The 18650 lithium ion battery are separated. So the possibility of its short circuit has been reduced to the extreme. A protective plate can be added to prevent the battery from overcharging and over-discharging, which also extends the battery life.
4, high voltage
The voltage of 18650 lithium ion battery is generally 3.6V, 3.8V and 4.2V, which is much higher than the 1.2V voltage of NiCd and NiMH batteries.
5, no memory effect
It is not necessary to empty the remaining power before charging, which is convenient to use.
6, can be combined in series or parallel to form a 18650 lithium ion battery pack
7, a wide range of uses
Electronic devices such as laptops, walkie-talkies, portable DVDs, instrumentation, audio equipment, model airplanes, toys, video cameras, digital cameras, etc.
