LED Flashlight

LED Flashlight Lithium Battery Manufacturer

LED flashlight is a new type of lighting tool that uses light-emitting diodes as a light source. It has the advantages of power saving, durability, and strong brightness. LED flashlights are used for hiking, camping, night riding, hunting, searching, diving, cave exploration, etc. LED flashlight usually choose 18650 lithium battery as its power source.


Why Choose Lithium Battery For LED Flashlights?

Large Capacity: The capacity of 18650 lithium batteries is generally between 1200mah and 3350mah, while the general battery capacity is only about 800. If you parellel two 18650 lithium batteries, then the capacity of 18650 lithium battery packs can be piled up.

Long Life: The 18650 lithium battery has a long service life, and the cycle life can reach more than 500 times during normal usage, which is more than twice that of ordinary batteries.

High Safety Performance: 18650 lithium battery has high safety performance, no explosion, no combustion; non-toxic, non-polluting, RoHS trademark certification; various safety performance in one go, the number of cycles is greater than 500 times; good high temperature resistance, power efficiency under 65 degrees reaches 100%.In order to prevent short-circuit of the battery, the positive and negative electrodes of the 18650 lithium battery are separated.Therefore, the possibility of short-circuiting has been reduced to the extreme.A protection board can be installed to avoid overcharging and over discharge of the battery, which can also 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: there is no need 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. It can reach the level of 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.
