-Electrical Characteristics-

ltem Conditions Criteria
Ful Charge The battery is charged at a 0.909A constant current until the voltage reaches 4.20V. The current is then reduced to keep a constant voltage of 4.20V.The total charging time is 5.0 hours at 25°C -
Capacity (1)Within 1 hour after fully charging at 25 as per item 6.1 the battery is discharged at 0.606A continuously to 2.5V at 25°C More than 300 min
(2) Within 1 hour after fully charging at 25 as per item 6.1,the battery is discharged at 3.03A continuously to 2.5V at 25°℃. More than 54 min
6.3 Cycle Life After the battery has been subjected to 300 repeated charge and discharge cycles (charged by CC-CV of 0.909A-4.20 for 5.0 hours; discharged by CC of 3.03A to 2.5V at 25° ),the discharge time is measured as per ltem 6.2,(2) More than 38 min.
Temperature Characteristics (1) Within 1 hour afterfully charging at 25° as per item 6.1,the battery is stored at 0C for 3 hours. The discharge time is then measured as per tem 6.2, (2)at 0C.

(2) Within 1 hour after fully charging at 25 as per item6.1,the battery is stored at 60° for 3 hours. The discharge time is then measured as per ltem 6.2,(2)at 60℃
More than 30min

More than 50min.
Storage at Fully Charged State Afterfully charging at 25℃per item6.1,he battery is stored for 20 days at 60℃ After storage, the battery is held at 25℃ for 3 hours. Then, the discharge timeis measured as per Item 6.2,(2).

Then, the same batteryis fully charged again and discharged a second time and measured as perltem 6.2, (2).
More than 30min

More than 40min.
Storage at Fully Discharged State After fully charging at 25℃ , the battery is discharged as per item6.2,(2).Then, the batteryis stored for 20 days at 60 After storage, the batteryis held at 25 for 3 hours. Then, the discharge time is measured as per ltem 6.2,(2) More than 50 min
Drop After fuly charging at 25 , the cell is dropped 3 times in random directions from a height of 1 m onto a flat surface of concrete No rupture, no fire


1). Do not disassemble, dispose of in fire, heat or short circuit.
2).Do not insert batteries with the(+)and(-)reversed.
3). Do not mix fresh batteries with used batteries.
4).Do not submerge the battery in water

Storage Measures For Daily Lithium Battery Users

1. For Lithium-ion batteries which need to be stored for a long time and not used, they should be kept in a state of 50%-60% charge. They should be recharged every 3 months and recharged every half a year.

2. Attention should be paid to moisture-proof and moisture-proof, to prevent squeezing, collision, etc., to avoid battery damage.

3. It is forbidden to use or place the battery at high temperatures (in hot sunlight or in very hot cars), otherwise it may cause the battery to overheat, catch fire or fail in function, and shorten its life.

4. It is forbidden to store in places with strong static electricity and strong magnetic fields, otherwise it will easily destroy the battery safety protection device and bring unsafe hidden dangers.

5. If the battery emits an odor, fever, discoloration, deformation, or any abnormality during use, storage, or charging, immediately remove the battery from the device or charger and disable it.
