Q: How is the capacity grading accuracy of VX4 charger?

The VX4 charger uses a 300mA discharge current to test battery capacity. Under the comparison test of the XTAR lab, with the same test condition, a randomly picked XTAR 1.5V AA 1200mWh battery had real capacity 1161mWh by VX4 charger,

Q: I tested XTAR 4150mWh with VX4, the value is only 3500-3750mWh, is this normal ?

XTAR AA 1.5V 4150mWh Li-ion battery, the original cell is 3.6V rated capacity of 1150mAh; the original cell's power is: 3.6V * 1150mAh = 4140mWh; this is also the origin of our labeling 4150mWh.

Q: I tested XTAR 4150mWh with VX4, the value is only 3500-3750mWh, is this normal ?

When converting a 3.6V primary cell battery to a 1.5V constant voltage lithium battery, there is a loss of about 10% due to the influence of the protection board and the bucking circuit; the actual tested capacity is around 3750mWh.

Q: For 3.6/3.7V Li-ion battery, would the set of 2.5V discharge cut-off voltage cause a over-discharging?

No, it won't. According to the international testing standard IEC 61960-3 2017, the discharge cut-off voltage for 3.6/3.7V Li-ion batteries is 2.5V.
