Performance

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 and measurement shall be done under temperature of 25±2℃ and relative humidity of 45~85%. The test results are not affected evidently by such conditions of temperature 15~30℃ or humidity 25~85%RH.5.2 Measuring Instrument or Apparatus.

2 Measuring Instrument or Apparatus 

2.1 Dimension Measuring Instrument 

The dimension measurement shall be implemented by instruments with equal or more precision scale

of 0.01mm.

 Q1: Can I have some samples for testing quality?

 A1:  Yes, you can buy some samples of any our products for testing quality and market.
 
Q2: How should I pay?
A2: You can pay via T/T,L/C at sight,Western Union, Cash etc., 100% T/T in advance for samples. For large quantities, 30% T/T in advance as soon as  order confirmed and the balance before shipping via T/T or L/C etc. If you prefer other payment terms, please contact us freely.

Q5: Are you factory?

A5: yes,we are factory.

Q6. Can you explain in detail how you match cells for a battery pack before you assembling the pack?
A6: We will do the following things before assembling the pack:
   a. Select capacity, same capacities cells for one pack
   b.  Measure the voltage, same voltage cells for one pack(difference is under 0.02v per cell)
   c.  Measure the inner resistance,same IR cells for one pack (difference is under 1m Ohm)
  All above steps are very strict to make sure the pack performance is perfect.

Q7: What&rsquos your advantage compared with other suppliers?
A7: a. High quality batteries: Our batteries are in enough capacity, and lower in RI,
   Before shipment, we will inspect the products and ensure the quality which are well approved by our clients.
