Since no one has answered to date here is a bit of information:
I have three generations of duraloops - eneloops have never been easy to obtain where I live but for a long time I could get good prices on the duracell versions. The three I have are:
- duracell PreCharged - 2000 mah (aa) - lots of these and they still have good capacity after quite a lot of use.
- duracell StayCharged Duralock - 2000 mah (aa) - 4 of these and for all intents and purposes they seem to be very similar or the same as 1) above. They have a green band with “duralock” on it just above the half way point.
- duracell Ion Core perCharged - 2400 mah (aa) - haven’t used these much. They are somewhat heavier and a tiny bit bigger than 1 and 2) above and have a black positive end. I obtained them from Mec.ca and it appears that is all they sell now.
I have a few aaa’s the same as 1) above. One however is made in China and has a black positive end. I haven’t taken the time to discover if it performs similar to the white ended “made in Japan” aaa’s as they are only used in small flashlights.
It is my understanding 1,2 and 3 above are rebadged eneloops but I don’t know how to match the different generations…
A couple of links with further info:
Overview: All Eneloop batteries 2005-2023 - very detailed description of the various generations of eneloops.
A quick search should also find discussion of which generation of eneloop is the same as the duraloops.
