Product Details

Test conditions

1 Standard Test Conditions

Test should be conducted with new batteries within one month after shipment from our factory and the cells shall not be cycled more than five times before the test. Unless otherwise defined, test stated in this specification should be conducted at temperature of 25±2℃, humidity 45~85% and Test should be performed under atmospheric conditions with 86KPa~106KPa pressure.


2 Measuring Equipment

2.1 Dimension Measuring Instrument

The dimension measurement shall be implemented by instruments with equal or more precision scale of 0.01mm.

2.2 Voltmeter

Standard class specified in the national standard or more sensitive class having inner impedance more than 10 MΩ

2.3 Impedance Meter

Impedance shall be measured by a sinusoidal alternating current method (1kHz LCR meter).


3 Standard Charge

The standard charge means charging the cell with charge current 0.5CA and constant voltage 3.65V at (25±2)℃, 0.05CA cutoff.


4 Quick Charge

The standard charge means charging the cell with charge current 1.0CA and constant voltage 3.65V at (25±2)℃, 0.05CA cutoff.


5 Standard Discharge

The standard charge means discharging the cell with charge current 0.5CA with 3.65V cutoff at (25±2)℃.

 

Transportation

Battery for shipping should be packed in boxes with the condition of half charged. The Violent vibration, impact extrusion, sun and rain should be prevented during shipping. The battery is suitable for cars, trains, ships, aircraft and other transportation vehicles.


Storage and other matters

1 Long-term storage

Batteries should be  stored  (more  than 1  month)  indoor  with  a  dry and  clean  environment  at 0 ℃~35 ℃. Avoiding contact with corrosive substances and staying away from fire and heat source. The battery should be charged and discharged every 6 months. The voltage  for storage is between 3.20~3.31  V (30 ~ 50% SOC).


2 Other business

Any matters not mentioned in this specification, shall be negotiated by both parties.


Handling of Cells

1 Charging

1.1 Charging current

Charging current shall not exceed the maximum charging current in this specification. Otherwise it would cause the problem in charge and discharge performance, mechanical performance and safety performance.

1.2 Charging voltage

Charging voltage shall not exceed the maximum charging current in this specification. Otherwise it would cause the problem in charge and discharge performance, mechanical performance and safety performance.

1.3 Charging temperature

Batteries must be charged within the t ambient temperature range of 0 ℃~45 ℃.

1.4 Forbidding reverse charge

Battery should be connected correctly. It is strictly prohibited to reverse charge. Otherwise it will cause the battery scrap and produce safe hidden trouble.


2 Discharge

2.1 Discharging current

Discharge current shall not exceed the maximum charging current in this specification; Otherwise it would cause dramatically capacity loss and overheating.

2.2 Discharge temperature

Batteries must be discharge within the ambient temperature range of -20 ℃~55 ℃.

2.3 Forbidding over-discharge

Battery management system should be installed to prevent over discharge during the usage. Over discharge will cause the battery scrap and produce safety hazard. It is necessary to state that for the battery not used for a long time, it may over discharge due to the self-discharge characteristics. To prevent the occurrence of over discharge, the battery should be regularly charge and the voltage should be remained above 3.2 V.


3 Connection

3.1 Polishing the pole with abrasive paper before use, otherwise it would cause bad contact or failure.

3.2 It is recommended to use copper connector to connect the battery.

3.3 Using the specific tools, such as spanner, to connect the battery.


4 Announce ment

Failure to observe the following precautions may result in battery leakage, overheating, explosion and/ or fire.
