The battery capacity provided by the manufacturer let go after the test

The battery capacity provided by the manufacturer let go after the test 11A.2 each cell sample subjected to the charge current is 3 times the normal manufacturer specified charging current, the battery connected to a DC power supply. Special charge current access is through a special series resistor sizes and specifications available. laptop battery Calculate the test of time:
tc = 2.5C/3Ic
tc-charge time (h); C-Capacity (Ah); Ic-makers generally specified charge current (A)
