IIRC, the Eneloops and “similar to Eneloops” were tested by someone over at CPF. The non-Eneloops didn’t test as well, especially after many cycles, but are probably close-enough if you can’t get real Japanese Eneloops or they are too pricey.
IMO, if you can get real Eneloops, go for them. They may be more pricey, but it amounts to a small fraction-of-a-penny per cycle.
Same for lithium-ion cells. Get quality name-brand cells from a trusted source. It’s not worth trying to save a buck or two. I just bought another bunch of 18650’s from Illum. Only 4 days to be delivered to Canada, and confident I’m getting genuine cells.
I’ve bought from China before, but there’s a good chance they’re fakes. They also don’t come packaged well from China (you don’t want damaged 18650’s), and it takes about 2 months to get them. Not worth it to save a few dollars. I’ll pay the extra penny per charge to save the hassle.
