Overview：Large capacity The capacity of 18650 lithium battery is generally between 1200mah ~ 3600mah, and the general battery capacity is only about 800mah. If combined into an 18650 lithium battery pack, the 18650 lithium battery pack can easily break through 5000mah .
18650 lithium-ion battery advantages
(1) Large capacity The capacity of 18650 lithium battery is generally between 1200mah ~ 3600mah, and the general battery capacity is only about 800mah. If combined into an 18650 lithium battery pack, the 18650 lithium battery pack can easily break through 5000mah .
(2), long life The 18650 lithium battery has a 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, no explosion, no combustion; non-toxic, no pollution, RoHS trademark certification; all kinds of safety performance in one go, cycle times more than 500 times; good high temperature resistance, 65 degrees The discharge efficiency reaches 100% under the conditions. 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 added to avoid overcharging and overcharging the battery, which can also extend the battery life.
(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-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 mobile phone. The standby time can reach the level of international standards. 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 hydrogen battery.
(7), can be combined in series or parallel to form 18650 lithium battery pack
(8), Wide range of use Electronic equipment such as notebook computers, walkie-talkies, portable DVDs, instruments, audio equipment, aeromodelling, toys, video cameras, digital cameras, etc.
