●Long cycle life: Charge and discharge cycles are ordered more than 500 times (with 80% capacity remained)。

●Low self-discharge: self-discharge less 10% per month.

●No memory effect:the state of charge before charge does not affect the discharge capacity.

●High energy density: The energy density of lithium battery is higher than that of lead-acid battery, nickel-cadmium battery and nickel-hydrogen battery. The volume capacity density of lithium battery is 320AH/L and the weight capacity density is 150Ah/kg.

●High operating voltage: The average working voltage of single cell is 3.7V.

●External short circuit test:After fully charged, the battery is short-circuited by conductor with the resistance of less than 5 0m Ω; the battery does not cause fire or explode.
●Pinpricking test:The battery should be fixed on the fixture of the safety device and beaten forcefully by the steel nail with the diameter of 2.5 mm, so that it is fully penetrated; the battery leaks and generates heat; the battery does not cause fire or explode.

●Thermal shock test:After fully charged, the battery is put into the oven and heated to 150℃at the rate of 5℃/min, which should be preserved for 30 minutes; the battery bulges and generates heat; the battery does not cause fire or explode.
●Overcharge test:Battery should be charged under the condition of 3C magnification and 5V voltage; battery does not cause fire or explode.

Caution:

Use a specified charger

keep the battery in a cool dry surrounding if it stands by.

Do not short circuit the battery terminals

DO not disassemble the battery

DO not throw the battery into fire or heat
