What voltage battery is it?

Sorry. I wasn't very clear in my original post.
The radio uses three 1.5 volt NiMH AA batteries.
It came with three 1100 mAh double A's
To charge them in the radio one follows a procedure
of selecting "charge", then a number of hours to
charge by pressing 1 through 9 on the number keys.
Pressing 8 charges for 8 hours, etc. This is done
with the radio "off" and plugged into the wall outlet.

The radio came with a converter to change my 110v
to 220v so I can use it here in the U.S.

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
