Earlier on, before low self discharge nimh, I bought name brand and 99 cent ebay AA nimh cells and almost all those cells over 10+ years have lost 50% or more of their capacity.  The ebay cells never had 50% to begin with even brand new.

These cells would lose about 1% of their capacity each day brand new.  The name brands would be used in my digital camera and I learned to charge them the night before if I wanted best performance and capacity. I now use these cells for small non critical things where capacity doesn't matter. 

The 10+ year old Eneloops and it's various label variants goes into remote, camera, controller, mouse, toothbrush, shaver, etc.  Pretty much all my Eneloops, when I last checked about 1 year ago, are close to their rated capacity as reported by my charger refresh/capacity check function.

PS. I have some Duracell pre-charged 1900 mAh AA cells that are made in Japan.  These are reported to be Eneloops with a Duracell wrapper.

I use alkaline AA and AAA cells for the lowest drain devices or devices that I use very rarely like remotes.  Everything else, which amounts to my GPS, carry flashlight, calculator, and camera, gets 4th generation Eneloops.  When I was using a wireless mouse and keyboard, those got Eneloops also.

My current set of Eneloops were purchased in July of 2017 and my battery charger and analyzer shows that they are doing fine with better than 90% capacity remaining.  My previous set lasted at least 10 years.

In Australia you really can't beat IKEA LADDA. They just released a new line (blue-green in colour) which is much cheaper than the old one, reports say they're still made in Japan. At something like $1.50-$2 per cell I put them in literally everything I can.

There is only one battery factory in Japan that makes low discharge NiMH rechargeable cells, so if you're out shopping and see "made in Japan" then you know it's made by FDK. (long story short Sanyo were forced to sell their factory to preserve competition)

Duracells have leaked so badly for so many years, it's cheaper to use LSD batteries.
Ikea summer sale was under $1 each for (white) Ladda rechargeables, so I loaded up. The new green Ladda are lower capacity.
They're not the same as Eneloops for charge and discharge behavior. All NiMh I've had need a "top up" charge to 1.5Vpc for some reason or they just go lazy if you never take the end of charge voltage up there.

I can't find Eneloops to buy without the *@W#%&$@ free charger so I have way too many of those, and they are so slow.

That's an excellent price.  I'm assuming that sale is over?

I don't live close to Ikea, but I see they have 1900 mAh package of 4 for $5 CAD.  If they are made in Japan (it's not obvious from the photos) and lsd, that's still a good everyday price vs throwaway alkalines.  Charge them 5 times and you get your money back.  I'm using 30 cents for your standard Costco AA cell.
