Advantages and disadvantages of 18650 lithium battery.
Advantages
1. The capacity of a high-capacity 18650 lithium battery is generally between 1200mAh and 3600mAh, while the capacity of a typical battery is only about 800. If combined into an 18650 lithium battery pack, it can easily exceed 5000mAh.

2. 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 ordinary batteries.
3. High safety performance 18650 lithium battery has high safety performance, no explosion, no combustion; Non toxic, non polluting, identified by RoHS trademark; All kinds of safety performance are achieved in one go, with more than 500 loops; 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 possibility of it experiencing a short circuit has been reduced to the extreme. Protective plates can be installed to prevent overcharging and overdischarging of the battery, which can also extend its lifespan.
4. The voltage of 18650 lithium batteries 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 and there is no need to empty the remaining battery before charging, making it easy to use.
6. Low internal resistance: The internal resistance of polymer battery cells is lower than that of general 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, which can fully reach the level of international standards. This polymer lithium battery that supports high discharge current is an ideal choice for remote control models and has become the most promising alternative to nickel hydrogen batteries.
7. Can be combined in series or parallel to form 18650 lithium battery pack
8. Widely applicable electronic devices such as laptops, walkie talkies, portable DVDs, instruments, audio equipment, model airplanes, toys, cameras, digital cameras, etc
