I know the Iron core are Eneloop Pro Re-Wraps. However the brand new 2020 models that came out last week have different packaging yet again. Rest assured, they are still Eneloop Pro's. I will post a picture of them below. I lucked out and got a 4 pack of AAA's for under $7 plus under 70 cents sales tax in rural Wisconsin. That, is obviously a good deal. The (perhaps not so)interesting thing is the PowerX are rated higher capacity. Once the Duraloops cycle and charge the first time, they hold more MAH than the PowerX. Go figure. Inflated claims Vs. conservative ones. The Japanese tend to be modest. Even though Duracell is an American company I imagine Panasonic had some say in the matter. I actually use much better chargers than both of those. "Hobby" grade chargers. Plus the La Crosse. I enjoyed seeing those PowerX I cooked plummet on discharge The others may be pretty good still Since I caught them pretty early. Although I do not really care to mess with PowrerX when I can obtain Duraloops for a song. Plus I hardly need very many of these very often. Especially the way they last in low drain devices. They just received a 48 hour Cryo treatment at -200C. That should help regain their longevity quite a bit. The last ones lasting over 11 years is plenty good enough for my expectations though.
Oh, I cannot post attachments. Here is what the new ones look like and notice the price as well. Where the income level is below poverty they are going to have to adjust the prices I guess. AFAIK the brand new batteries were not on clearance:

Actually, now I have seen packages of them online with 850,900 an 950MAH respectively printed on the back. May be market specific. I have no clue about that, but seems like a good guess to me. They are all the same and al of mine that are "rated" to be 850MAH each charged to over 1000MAH. Even at $10.45 with free same day delivery(Prime members) and no tax most likely it is a better deal than Eneloops. Especially, now that people are recently reporting failures here as of late.
