Specification of Product and Test Method

Test items

Test Methods


  1. Dimension

In order to ensure accurate measurement, it is recommended to use a caliper with an accuracy of 0.02mm or more. Also, to prevent short circuits, it is recommended to place insulating material on the vernier caliper when testing.



  1. Open circuit voltage

The accuracy of the DDM is at least 0.25%, and its internal circuit resistance is greater than 1MΩ.


  1. Instantaneous short-circuit

When using a pointer multimeter to test, make sure that each test does not exceed 0.5 minutes to avoid repetition. Allow at least 30 minutes before proceeding to the next test.


  1. Appearance

Visual test

Batteries must not have any blemishes, stains, deformations, uneven color tone, electrolyte leakage, or other defects. When installing it into the appliance, make sure that both terminals are properly connected.

  1. Quick Discharged Volume

The recommended temperature range is 20±2°C with a maximum humidity of 75%. The discharge load should be 3kΩ and the termination voltage should be 2.0V.

≥160 hours

  1. Vibrate test

The vibrating frequency should be maintained at a range of 100-150 times per minute while continuously vibrating for a duration of 1 hour.


7.  High temperature-resistant of weeping performance

Storage 30 days Under 45±2 conditions

leakage %≤0.0001

8.  Circuit load of weeping performance

When the voltage reaches 2.0V, keep the load continuously discharged for 5 hours.

No leakage

Remark2:The bearing boundary dimension of this product, dimension are under IEC 60086-2:2007 standard(GB/T8897.2-2008,Battery,Related to 2nd part )Remark3:1.Extensive experiments were performed to verify the above tests.2.The primary battery standards formulated by the company all exceed GB/T8897 national standards. These internal standards are significantly more stringent.3.If necessary or according to the specific requirements of customers, our company can adopt any test method provided by customers.

Instructions for Usage and Safety
The battery consists of lithium, organic, solvent, and other combustible materials.  Proper handling of the battery is of utmost importance; otherwise, the battery could lead to distortion, leakage (accidental
seepage of liquid), overheating, explosion, or fire and cause bodily injury or damage to equipment.  Please strictly comply with the following instructions to avoid the occurrence of accident.

WARNING for Handling
● Do Not Ingest
The battery should be property stored and keep away from children in order to avoid them to put it into their mouths and ingest it.  However, if it happens, you should immediately take them to the hospital.

● Do Not Recharge
The battery is not a rechargeable battery.  You should never charge it as it could generate gas and internal short-circuiting, leading to distortion, leakage, overheating, explosion, or fire.

● Do Not Make Hot
If the battery is being heated to more than 100 degree centigrade, it would increase the internal pressure resulting distortion, leakage, overheating, explosion, or fire.

● Do Not Burn
If the battery is burnt or put to flame, the lithium metal will melt and cause explosion or fire.

● Do Not Dismantle
The battery should not be dismantled as it will cause damage to separator or gasket resulting distortion, leakage, overheating, explosion, or fire

● Do Not Make Improper Setting
The improper setting of the battery could lead to short-circuiting, charging or forced-discharging and distortion, leakage, overheating, explosion, or fire could be occasioned as a result.  When setting, the positive and negative terminals should not be reversed.

● Do Not Short-circuit The Battery
The short-circuit should be avoided for positive and negative terminals.  Do you carry or keep battery with metal goods; otherwise, battery could occasion distortion, leakage, overheating, explosion, or fire.

● Do Not Directly Weld The Terminal or Wire to The Body of The Battery
The welding will cause heat and occasion lithium melted or insulating material damaged in the battery.  As a result, the distorting, leakage, overheating, explosion, or fire would be caused.  The battery should not be soldered directly to equipment which it must be done only on tabs or leads.  The temperature of soldering iron must not be over 50 degree C and the soldering time must not be more than 5 seconds; it is important to keep the temperature low and the time short.  The soldering bath should not be used as the board with battery could stop on the bath or the battery could drop into the bath.  It should avoid taking excessive solder because it could go to unintended portion on the board resulting short or charge of the battery.

● Do Not Use Different Batteries Together
It must be avoided for using different batteries collectively because batteries of different types or used and new or different manufacturers could occasion distortion, leakage, overheating, explosion, or fire.  Please obtain advice from Shenzhen Greenmax Technology Co., Ltd. if it is necessary for using two or more batteries connected in series or in parallel.

● Do Not Touch The Liquid Leaked Out of Battery
In case the liquid leaked and get into the mouth, you should immediately rinse your mouth.  In case the liquid gets into your eyes, you should immediately flush eyes with water.  In any event, you should go to the hospital and have proper treatment from a medical practitioner.

● Do Not Bring Fire Close to Battery Liquid
If the leakage or strange smell is found, immediately put the battery away from fire as the leaked liquid is combustible.

● Do Not Keep in Touch with Battery
Try to avoid keeping the battery in touch with the skin as it will get hurt.
