Advantages of 18650 lithium battery
- Large capacity
The capacity of 18650 lithium batteries is generally between 1200mah and 3600mah, while the general battery capacity is only about 800mah. If combined into a 18650 lithium battery pack, the capacity of 18650 pack can easily break through 5000mah.
- Long 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.
- High safety performance
The 18650 lithium battery has high safety performance. For one hand, It do not explode and catch fire. On the other hand, it is non-toxic and non-polluting.
We can see its structure. There is a galvanized steel shell to endure inner pressure. Thus it will not explode.
Further more, 18650 lithium battery has passed RoHS( Restriction of Hazardous Substance) trademark certification.
As we mentioned above, the number of cycles is greater than 500 times. It has good high temperature resistance. Because and the power-up efficiency can reach 100% even under 65℃.
In order to prevent short-circuiting of the battery, the positive and negative electrodes of the 18650 lithium battery are separated. Therefore, the probability of it short-circuiting is extremely low.
In order to avoid overcharging and over-discharging the battery, a protective board is installed inside. This method also can extend the service life of the battery.
- High voltage
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-metal hydride batteries.
- No memory effect
The 18650 lithium battery does not have to empty the remaining power before charging, which is easy to use.
- 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 below 35mW, which greatly reduces the self-consumption of the battery and extends the standby time of the mobile phone.
This is completely in line with international standards. This kind of polymer lithium battery that supports large discharge currents is an ideal choice for remote control models and has become the most promising alternative to nickel-metal hydride batteries.
- Wide range of use
18650 battery can be used for notebook computers, walkie-talkie, portable DVDs, instrumentation, audio equipment, model aircraft, toys, video cameras, digital cameras and other electronic equipment
- Flexible Design
It can be combined in series or in parallel into a 18650 lithium battery pack
