With the increasing development of wireless technology, there are more and more lithium battery products in everyone's hands!

From small power banks to large electric vehicles, low-power lithium battery products and high-power lithium battery products, the 18650 battery is the most used!For people who are often in contact with power tools, it is very important to clearly understand the advantages of 18650 battery!

1. The capacity of 18650 lithium battery is generally between 1200mah and 3600mah, and 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 service life The 18650 lithium battery has a long service life, and the cycle life can reach more than 500 times during 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, the positive and negative electrodes of 18650 lithium battery are separated. Therefore, the possibility of short-circuiting has been reduced to the extreme. A protection board can be added to avoid overcharging and overdischarging of the battery, which can also prolong 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. There is 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 the polymer battery is smaller than that of the general liquid battery. The internal resistance of the domestic polymer battery 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 reach the level in line with international standards. This polymer lithium battery that supports large discharge current is an ideal choice for remote control models, and has become the most promising product to replace nickel-metal hydride batteries.

7. It can be combined in series or in parallel to form a 18650 lithium battery pack

8. Wide range of use: notebook computers, walkie-talkies, portable DVDs, instrumentation, audio equipment, model aircraft, toys, video cameras, digital cameras and other electronic equipment.
