Thanks, but I am looking for tests across a wide range of cells. Or just “the best ones”. Not using AA cells in an adapter; primarily because I have had no real success with the adapters. I have a bunch of Eneloops, but I have not seen C cells from them that are not an AA stuck in a fake battery case. And I would really rather recharge 4 batteries instead of 12. I am also in the US (the PNW means I am at the upper left corner).

I am seeing Tenergy rated at 5000 mAH. But a failed 4000 mAH battery from them is why I am looking for replacements. So I am a bit leery of Tenergy. And I want a matched set. And if 5000 is real, I would like to go there.
