I posted the same question in the yahoo Kaito-Degen1102
group and was told that dividing the capacity of the batteries
by the charge current would give me the number
of hours to charge. 1100 / 220 = 5 hours

Fairly close. But it may take more like 7.5 hours, if they used a .1C
rate for 15 hours as the "standard". IE: 110ma for 15 hours. If you
double the current to 220ma, I might expect 7.5 hours instead of 5.
But I'd watch the voltage to get an idea when full charge really
occurs. It will vary per battery and condition of the cells, etc...
