I really appreciate all the help you've given on this. Thank you very much!

The rechargeable batteries are not marked at all, and had it not been called to my attention, I know that I would not even have thought that they could overpower the flashlight.

I tracked down the charger on the Battery Station's site, and from all indications it appears that it is the 3.7V version and the batteries 3.6V.
