Yep, over a decade ago. I imagine, if the batteries didn't meet it, I'd think Panasonic would be losing their butts replacing a bad product at a 10X failure rate. Even the "first generation" Eneloops didn't have numbers as abysmal as some have claimed here, twenty years ago.
By any chance, did someone confuse the Eneloop charge cycles with 1970's NiDd's? Now THOSE were junk, I wouldn't even claim 50 cycles for those, 25, maybe.
As I said, I'm only about 75 weeks/cycles into a few dozen without problems. I'm not sure if/when they should be "reconditioned", probably when I notice some sort of issue, but nothing has stood out.
As for why I chose that particular NiMH, it was after reading nothing but positive comments in the radio forums for about 15 years, and the Pro model, for the high capacity, and current, which my applications require.
Another thing to consider, for those that have had them fail, if any. What kind of charger was used, and how were the batteries treated? Murdered after every charge, then allowed to bake for hours or days, by the wrong type of NiMH charger, or a charger for an entirely different battery chemistry, charge rate, or voltage? The Eneloops are the most expensive AA cells I've ever owned, so I bought the matching charger/reconditioner.
We'll see how it goes.
