18650 battery characteristics.

18650 battery characteristics.

Generally speaking, 18650 lithium battery packs have the following benefits.

1. Widely applicable

Laptops, walkie talkies, portable DVDs, instruments, audio equipment, model aircraft, toys, cameras, digital cameras, and other electronic devices.
2. Series connection
Can be combined in series or parallel to form 18650 lithium battery packs.
3. Low internal resistance

The internal resistance of polymer battery cells is smaller than that of typical liquid battery cells, and the internal resistance of domestic polymer battery cells can even reach below 35m Ω, greatly reducing the self consumption of batteries and extending the standby time of mobile phones, fully reaching the level of world integration. This polymer lithium battery that supports high discharge current is an ideal choice for remote control models and 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 batteries is usually 3.6V, 3.8V, and 4.2V, much higher than the 1.2V voltage of nickel cadmium and nickel hydrogen batteries.
6. High security function
18650 lithium battery has high safety function, does not explode or burn; Non toxic, pollution-free, certified with RoHS trademark; All kinds of safety functions are integrated in one go, with more than 500 cycles; Good high temperature resistance, with a discharge efficiency of 100% at 65 degrees Celsius. To prevent battery short circuits, the positive and negative poles of 18650 lithium batteries are separated. So the occurrence of short circuits may have been reduced to the extreme. It is possible to install a protective plate to prevent overcharging and overdischarging of the battery, which can also extend the lifespan of the battery.
7. Long lifespan application
The lifespan of 18650 lithium batteries is very long, with a normal cycle life of over 500 times, which is more than twice that of regular batteries.
8. Large capacity
