I wouldn't use that charger on Eneloop batteries. It charges at a constant high rate @ over 1A. Those batteries will not be happy with that high rate of charge. The switch just changes the charge characteristics and not the overall rate.
I rather disagree with that.
Look at this spec sheet:

I have been using one of those automatic balance chargers for all of mine in NiMH mode and set the max charge current at 1A or 2A depending on the time I have.
John's charger should do fine on either the 500 or 1000 setting
