> Some heavy users do go for the higher capacity with a full understanding of the disadvantages, but that's not the majority of the market. And there's part of your answer as to why a consumer might try rechargables and still reject them, even today: self-discharge too high. > Eneloops came out in 2005. So 13 years ago, whereas NiMH was 1989, or a 16 year spread. Wait at least another 3 years. Actually, wait until only LSD is readily available. Then wait the number of years until how long it will have been from then since 1989. > I don't see a size difference between a 4th-generation Eneloop AAA and a random Duracell alkaline, but I don't have calipers to measure precisely. The specs are probably available, but the more important question isn't whether your particular Eneloops are small enough, but if the vast majority (and AmazonBasics and if there's any other popular enough brand) are. Tiny variations in size can not just prevent the battery from going in in the first place, but, worse, keep it from coming back out.
