Electrical Characteristics

Test Method Criterion
Full Charge The battery is charged at a 1.155A constant current until the voltage reaches 4.10 V. The current is then reduced to keep a constant voltage of 4.10 V. The total charging time is 4 hours at 25°C.
Capacity ①Within 1hour after fully charged, discharge at 0.462A continuously down to 2.5V end voltage.

②Within 1hour after fully charged, discharge at 1.0C(=2.15)A continuously down to 3.0V end voltage.
≥ 300min.

≥ 54min.
Cycle Life After the battery has been subjected to 1000 repeated charge and discharge cycles below contition. Charged by CC-CV of 1.155A – 4.10 V for 77mA cut, then rest for 10min. Discharged by CC of 1.155 A to 2.5 V at 25°C then rest for 10min. The discharge time is measured as per Item7.2, (1)after 1000 cycles ≥ 240min.
Temperature Characteristics (1) Within 1 hour after fully charging at 25°C as per item 7.1, the battery is stored at 0°C for 3 hours. The discharge time is then measured as per Item 7.2,

(2) at 0°C.(2) Within 1 hour after fully charging at 25°C as per item 7.1, the battery is stored at 60°C for 3 hours. The discharge time is then measured as per Item 7.2, (2) at 60°C
≥ 30min.

≥ 50min.
Storage at Fully Charged State After fully charging at 25°C as per item 7.1, the battery is stored for 20 days at 60°C After storage, the battery is held at 25°C for 3 hours. Then, the discharge time is measured as per Item 7.2, (2).

Then, the same battery is fully charged again and discharged a second time and measured as per Item 7.2, (2) at 25°C.

≥ 30min.

≥ 40min
Storage at Fully Discharged State After fully charging at 25°C, the battery is discharged as per Item 7.2, (2). Then, the battery is stored for 20 days at 60°C. After storage, the battery is held at 25°C for 3 hours and is then fully charged as per item 7.1. Then, the discharge time is measured as per Item 7.2, (2) at 25°C. ≥ 50min
Drop After fully 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


All tests shall be conducted with new cell delivered within the last 7 days. Tests shall be performed at a temperature of 25±2°C and a humidity of 65±20% (the standard temperature tolerance for Class 2 and the standard humidity tolerance for Class 20, respectively, as specified by JIS Z 8703, Standard Atmospheric Conditions for Testing). The precision of the voltmeter and ammeter used in the tests shall be higher than Class 0.5 as specified by JIS C 1102-2, Special Requirements for Ammeters and Voltmeters.Cells are able to meet criteria in item 7 in accordance with the described test condition, not actual usage condition.

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.
