I still have some of the AA rad-shack NiMh and just got done testing them to just over 1000mah. they will likely be recycled.
AA Energizer 2500mah cells are coming in at over 2000mah.
AAA Duracell 1000mah are still showing better than 1000mah except one of four was dead as a doornail.
I am now testing the less known selection.
Just the fake ones that I bought from DX around four years ago. They’re not LSD and seemed to go flat within a week.
Otherwise, the Duraloops and, I think, generation 1 eneloops that I’ve got are fine with the exception of one. I’ve got one that the Maha C9000 says its capacity is down to 1600mAh. Compared this to its siblings which are in the 1850mAh mark, that’s a 13.5% drop in capacity over 2-3 years.
None. I do keep them paired and try to maintain them right, but it’s not like I’ve put any kind of effort into them. My Opus charger shows the 4+ year old ones as slightly degraded (1,850-ish), and I’m starting to believe their marketing hype, which claims, what about 2,000 cycles? A few of the knockoff brands I tried have gone downhill after extensive use. It’s funny, I have a pair of “Enitime” cells that test just as good as the Enloops on my Opus, but for high-drain devices like with my Canon point-and-shoot, their capacity goes to sh*t in a hand basket. Where the Eneloops just keep on chugging along. I get about 4 shots on those Enitimes before the battery warning starts blinking on the Canon. A couple years ago I went to the King Tut and Chihuly gardens in Seattle and got almost 1,000 photos (no flash) off a pair of Eneloops. I’ve been a fanboy ever since. EDIT: I’m not sure I believe that it’s 80% or 90% charge after a year on the shelf, but they sure beat normal NiMH cells.
I have about 70 eneloops total, roughly 40 aa and 30 aaa.
The oldest ones I have are first gen aa’s from 2007. I’ve never had one fail to perform yet.
Never recycled a single one although I don’t put them threw not nearly as many cycles as others have around here and my oldest ones are second gens. I have since purchasing a decent number of 3/4th gens from ChibiM to replace almost all of my non-lsd cells that I have bought from various brands with some being in the 10year old range after testing them out on the BT-C3100 and seeing how down their capacity is or how crappy they actually are in comparison.
Most common failure for me, Nicads I bought from like Radio Shack, with tabs to go into some piece of electronics and they leaked before I got around to using them. Ditto some from ebay, dead or leaked before I could use them.
I’ve been testing and culling old nicad and nimh so I can rotate more new LSD types into regular use, and seems that many of the sets of 4 have one or two bad and the rest pretty good. I ended up buying more flashlights to put the cells in instead of leaving on the shelf.
Total Eneloops = 268 (AA=180 / AAA=88) 
Over 50% of them have been supplied by my secret BLF dealer.......BLF Eneloop dealer that is. lol
In 4 yrs. or so I haven't had any eneloops go bad. The oldest I have are dated Sept. 2008 and they still are doing very well.
The link below is my old eneloop thread but I need to update the photos though since I've added over 60 more. I'm gonna need a bigger boat.....I mean shelf! lol

And yes, I know I need to see a shrink to help me deal with my eneloop obsession/addiction. 
I found a bunch of Eneloops in the bin at the local recycling centre. Some were tarnished and spoilt but I found 7AA and 3AAA that looked good. I charged them up and left them for a few months and recently tested some of the AAs. The worst were 1600mAh, the best 1800. Not a bad result. Sadly I’ve used the AAA, so will have to test them some other time but they look like they’ll get close to spec. Wonder why they were thrown away. Somebody thought they were too old and wanted an upgrade?
So the answer is no! I haven’t recycled any Eneloops but I have benefitted from someone else’s discards. Very green!
Great thread idea.
I haven't had to retire any yet. I have about 40 or so (haven't tried to keep track). Some from each generation. Haven't tested any as none have shown signs of diminished capacity yet.
Fishinfool I remember I used to think your collection was way over the top .
Now I understand and think instead of pooling our funds to get you therapy ...probably just simpler to buy you some neweloops.
you know you're a flashaholic ...when 270 eneloops doesn't seem unreasonable
There must be something wrong with me because I only have 4 eneloops. Thats 4 not 40 or 400 
Had them since about 2010 and they get plenty of use (and abuse) by the kids. I would have got some more, but free cells from work negate this.
’Loops are just bomb-proof 
Seven years, (AA’s and AAA’s), so far and still fine. Not one failure.
I’ve got one or two which are physically crushed, 4 of my Duraloops are rusty (from being used in an electric toothbrush), but I haven’t discarded any. I can’t seem to remember/find out when I bought any of them.
FWIW I don’t think I’ve had my cheapy LSD cells wear out yet either…

Nawh, you're fine. Just missing out a little. I'm guessing I have about 40, but I want double that. In addition to various flashlights, they're in many of my high drain (or want handy and ready to use) devices. Devices such as:
I'm sure I'm missing some stuff. Oh, and there are usually some loose cells fully charged waiting to swap in and some drained waiting to be charged.
I only have two AA’s. Looks like I should get a few more in AA and AAA if I find a sale.
Alkaline doesn’t have the guts to run stuff as hard as I want it to be ran.
I have four xx cells [2012 dated] which havent had much use as well as 20 odd normal eneloops. When i fully charge them[xx] to 1.49v, hot off the charger, my ea4 in turbo mode sends the battery voltage indicator flashing instantly and is about 15% down on output. The normal eneloops are fine and seems my XX’s have built up a dislike to discharging at higher current which is disappointing - any similar experiences with the XX.
I don’t think I have recycled any Eneloops just yet! My collection includes:
4 AAA Eneloops, 16 AAA Duracell Duraloops, 4 AAA Sony CycleEnergys Sonyloops (dated 2007 too!)
32 AA Duracell Duraloops, 4 AA Sony CycleEnergy Sonyloops
Of all these, even the 8 year old Sonyloops are holding on! There is only 1 set that has a bit higher than normal internal resistance, and that’s with a set of Duraloops that are in a Panasonic cordless phone whose charger I think is more timer based and could be overcharging the batteries a bit.
I have 32aa and 16aaa Eneloops for more than 6 years and they are still working great!
I also have 16 DuraLoops and 12 AppleLoops. 
I know, I know, get therapy.
