18650 3500mah battery

　　advantage

　　1. Large capacity The capacity of the 18650 lithium battery is generally between 1200mah and 3600mah, while 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 18650 lithium battery has a very 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. In order to prevent battery short circuit, the positive and negative electrodes of 18650 lithium battery are separated. Therefore, the possibility of short circuit phenomenon has been reduced to the extreme. A protection board can be installed 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 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.

　　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 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-consumption of batteries and prolongs the standby time of mobile phones. In time, it can fully reach the level of international standards. This kind of 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 NiMH batteries.

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

　　8. Wide range of applications Laptops, walkie-talkies, portable DVDs, instrumentation, audio equipment, aircraft models, toys, video cameras, digital cameras and other electronic equipment.
