Analysis of advantages and USES 18650 lithium batteries

Source: 2020 - 03 - 28 now hits: time 18650 lithium batteries advantages: 1. Large capacity lithium battery capacity is 1200 mah ~ 18650 3600 mah, the battery capacity is only 800 or so commonly, if combined into 18650 lithium-ion battery pack, 18650 is literally can break through 5000 mah lithium-ion battery pack. 2. Long life 18650 lithium battery service life is long, the normal use of the cycle of life is 500 times more than ordinary battery, is more than twice that of the ordinary batteries. 3. High safety performance, 18650 lithium-ion battery with high safety performance, explosion, burning; Non-toxic, non-polluting, through the RoHS certification trademark; All kinds of safety performance one pace reachs the designated position, cycle number more than 500 times; High temperature resistant performance, the working condition of 65 degrees power efficiency is as high as 100%. In order to prevent short circuit batteries, separate 18650 lithium battery of the positive and negative. Therefore, the possibility of short circuit is reduced to the limit. Can be mounted to the protection board, avoid battery overcharge and over discharge, still can extend battery life. 4. High voltage 18650 lithium battery voltage is commonly 3. 6 v, 3。 8v、4. 2 v, far higher than the nickel cadmium battery and 1 of nimh batteries. 2 v voltage. 5. No memory effect is convenient to use, don't need all the rest of the power run out before charging. 6. Small internal resistance, polymer battery internal resistance is less than the liquid battery, polymer battery internal resistance and even domestic can do below 35 m Ω, greatly reducing the battery power consumption, extend the standby time of mobile phone, can be achieved with the international level. The polymer lithium battery, support the large discharge current, is the ideal choice of the remote control model, is the most promising for nickel metal hydride batteries. 7. 18650 lithium batteries can be assembled 8 series or combination. Widely used laptops, walkie-talkie, portable DVD, instruments and meters, audio equipment, model aircraft, toys, cameras, digital cameras and other electronic equipment.
