Characteristics of 18,650 electric core

　　1. Large capacity

　　The capacity of the 18650 lithium battery cell is generally between 1200 mah and 3600 mah, while the capacity of the general battery cell is only about 800 mah. If the 18650 lithium battery cell group is combined, the 18650 lithium battery cell group can easily break through 5000 mah.

　　2. Long life

　　The service life of the 18650 lithium battery cell is very long. The cycle life can reach more than 500 times in normal use, more than twice that of the ordinary battery cell.

　　3. High safety performance

　　18650 lithium battery cell has high safety performance, no explosion and no combustion; Non toxic, pollution-free, RoHS trademark certification; All kinds of safety performance are achieved at one go, and the number of cycles is more than 500; High temperature resistance, discharge efficiency reaches 100% at 65 ℃. To prevent short circuit of the battery core, the positive and negative poles of the 18650 lithium battery core are separated. Therefore, the possibility of short circuit has been reduced to the extreme. The protective plate can be added to avoid overcharge and overdischarge of the electric core, which can also extend the service life of the electric core.

　　4. High voltage

　　The voltage of 18650 lithium battery cells is generally 3.6V, 3.8V and 4.2V, which is much higher than the 1.2V voltage of nickel cadmium and nickel hydrogen battery cells.

　　5. No memory effect

　　It is not necessary to empty the remaining power before charging, so it is convenient to use.

　　6. Small internal resistance

　　The internal resistance of the polymer core is smaller than that of the general liquid core. The internal resistance of the domestic polymer core can even be less than 35m Ω, greatly reducing the self consumption of the core, extending the standby time of the mobile phone, and fully reaching the level of international standards. This polymer lithium battery, which supports large discharge current, is an ideal choice for remote control models and is the most promising product to replace nickel metal hydride battery cells.
