Note: The original disassembled battery has been used for some time, and after our test, the capacity is still in the range of 3400~4000mAH.

We use professional battery testing equipment(EBC-A10H) to test our battery one by one before shipped out.

The test steps are as follow:
1. Set Mode : D-CC Mode, Test Val : 0.2C, Cutoff Volt : 2.75V to discharge.
2. Set Mode : C-CV Mode, Test Val : 0.5C, Voltage : 4.35V, Cutoff Curr : 0.05A to charge, it normally takes about 2 hours to get charge capacity.
3. Set Mode : D-CC Mode, Test Val : 0.2C, Cutoff Volt : 2.75V to discharge, it normally takes about 5 hours to get discharge capacity.
Finally, we can judge whether the battery is normal and whether the capacity is sufficient by test duration, curve and test results.
