    We can send batteries to most countries in the world, but a few countries can't send batteries.
    Please click seller guarantees on the right of the Feedback to see if your country can send battery.
    If your country can't send batteries but you still buy them,we will only refund you 85% of the sum.
    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 : 4.4V, Cutoff Curr : 0.05 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.
