Advantages of 18650 lithium battery

From:CTECHI GROUP Limited     Release time:2019-11-28

Overview:The capacity of 18650 lithium battery is generally between 1200mah ~ 3600mah, and the general battery capacity is only about 800. If combined into an 18650 lithium battery pack, the 18650 lithium battery pack can easily break through 5000mah.

Advantages of 18650 lithium battery:

1, large capacity

The capacity of 18650 lithium battery is generally between 1200mah ~ 3600mah, and the general battery capacity is only about 800. If combined into an 18650 lithium battery pack, the 18650 lithium battery pack can easily break through 5000mah.

2, long life

18650 lithium 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 safety performance

18650 lithium battery has high safety performance, no explosion, no combustion; non-toxic, no pollution, RoHS trademark certification; all kinds of safety performance in one go, cycle times more than 500 times; good high temperature resistance, discharge efficiency up to 100% at 65 degrees . To prevent battery short circuit, the positive and negative electrodes of 18650 lithium batteries are separated. So the possibility of its short circuit has been reduced to the extreme. A protection board can be added to avoid overcharging and overcharging the battery, which can also extend the battery life.

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

不必 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 less than 35mΩ, which greatly reduces the self-power consumption of the battery and extends the standby time of the mobile phone. International level. This kind of polymer lithium battery that supports large discharge current is an ideal choice for remote control model, and it has become the most promising product to replace nickel-metal hydride battery.

7, can be combined in series or parallel to form 18650 lithium battery pack

8. Wide range of use

Laptops, walkie-talkies, portable DVDs, instrumentation, audio equipment, aircraft models, toys, video cameras, digital cameras and other electronic equipment
