OK, there has been a lot of talk about the black vs the white topped Duracell precharged NIMH cells. The Japanese (White topped) cells are rumoured to be better since they are rebadged Eneloops. I have seen the post here with the NIMH testing, and this tells me some things I want to know. I want real world differences and comparisons. In the average high end AA lights (Nitecore D10, D20, Fenix, Olights, etc) what will be the performance difference? Will the Japanese cells last longer per charge? Will they last for more charging cycles? They tested these cells using current draws that I do not believe any light will do. Another CPF'er said they make a difference in hot wires. I have no idea what that is!! Any info would be appreciated!!
