Life: 1000 times
Special note: lithium batteries for flashlights, and then use a new battery before charging, lithium batteries do not overcharge and over-discharge, the battery is fully charged after stop, please charge immediately when the battery is low, otherwise the lithium battery can be easily damaged or even cause scrapped. (Full voltage is not higher than 4.2V, the discharge voltage is preferably not less than 3V
There are number of uses lithium batteries is limited, usually about 800 times. Each filled with a battery or electricity once every run, it will shorten life.
Lithium batteries - features
A. High Energy Density
Weight of the lithium-ion battery is half of the same capacity nickel-cadmium or nickel-metal hydride batteries, nickel cadmium volume is 40-50%, and 20-30% nickel hydrogen.
B. High Voltage
An operating voltage of the lithium-ion battery cells for 3.7V (mean value), the equivalent of three series of nickel-cadmium or nickel metal hydride batteries.
Lithium-ion batteries do not contain harmful metals such as cadmium, lead, mercury and the like.
D. contain lithium
Lithium-ion batteries do not contain lithium metal, and thus not subject to restrictions on the Prohibition of the transport aircraft carrying lithium batteries in passenger and other rules.
E. cycle life high
Under normal conditions, the lithium-ion battery charge and discharge cycles can be more than 500 times.
F. No memory effect
Memory effect refers to the nickel-cadmium batteries during charge and discharge cycles, the battery capacity decrease.Lithium-ion batteries are not the existence of such effects.
G. Fast Charge
Use a rated voltage of 4.2V constant-current constant-voltage lithium-ion battery charger can get a full charge within one to two hours.
Battery production process
battery cell cabinet
All batteries need a second sub-capacity，to ensure the battery capacity.1. Automatic sorting machine
High-tech machine,advanced technology,ensure the battery cells we need in the same weight, internal resistance, voltage, capacity
2. Bracket combination
Used the most secure combination of brackets, good cooling effect and more reliable.
3. Battery spot welding
Pure nickel spot welding, small internal resistance large over-currrent.
4. BMS systerm
With over charge protection over discharge protection. Excess charge current protection.
5. Epoxy board packaging
Flat and beautiful appearance. Security protection.
6. Charge and discharge test
Aging test,charge and discharge cycle testing for each battery pack, we guarantee to the customer each battery pack with the best quality.
