As a Wholesale 18650 Battery, share with you.
1. Large capacity 18650 Battery capacity is generally between 1200mah ~ 3600mah, and the general battery capacity is only about 800mah, if combined into an 18650 lithium battery pack, then 18650 lithium battery pack can easily break through 5000mah.
2. Long life 18650 lithium battery life is very long, the cycle life under normal use can reach more than 500 times, more than twice the ordinary battery.
3. High safety performance 18650 lithium battery has high safety performance, no explosion, no combustion; non-toxic, no pollution; various safety performances in one go, cycle times more than 500 times; good high temperature resistance, discharge efficiency up to 100% at 65 degrees . To prevent battery short circuit, the positive and negative electrodes of 18650 lithium batteries are separated. So the possibility of its short circuit has been reduced to the extreme. A protection board can be installed to avoid overcharging and overcharging the battery, which can also extend the battery life.
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. 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 cells is smaller than that of ordinary liquid cells. The internal resistance of domestic polymer cells can even reach below 35mΩ, which greatly reduces the self-consumption of the battery and extends the standby time of the mobile phone. Time can fully reach the international standard. This kind of polymer lithium battery that supports large discharge current is an ideal choice for remote control model, and it has become the most promising product to replace nickel-metal hydride battery.
7. Can be combined in series or parallel to form 18650 lithium battery pack
8. A wide range of use laptops, walkie-talkies, portable DVDs, instruments, audio equipment, aircraft models, toys, video cameras, digital cameras and other electronic equipment.
The biggest disadvantage of the 18650 lithium battery is that its volume has been fixed. It is not well positioned when installed in some notebooks or some products. Of course, this disadvantage can also be said to be an advantage. This is compared to other polymer lithium batteries and other lithium batteries. This is a disadvantage in terms of customizable and convertible sizes. Compared with some products with specified battery specifications, it has become an advantage.
The 18650 lithium battery is prone to short circuit or explosion, which is also relative to the polymer lithium battery. If it is relatively ordinary, this disadvantage is not so obvious.
