Just saw this and will have to investigate. I've been buying Duracell Ion Cores for $12/4 because I've heard that they are relabeled Eneloop XXs. I just bought another Maha C9000 off of BT and have some old Eneloops in it now, the real Sanyo ones that I was buying before you could get good NiMH in stores. Seems like they were a good investment, they have to be at least 6 years old now. And I haven't had any of them leak which is the main reason I started down that road in the first place!
