That's strange.. I have a Rayovac charger that does 8 cells at a time, got it for the Renewals probably 3 years ago, and it charges all my cells, NiCD's and NiMH's...
I prefer to use one of my old Milleniums to charge them though, faster and I feel better about the capabilities of the Millenium to not hurt the cells.
