Duracell 'StayCharged' batteries previously known as 'Pre-Charged'
- The name of this product has been changed to Duracell Rechargeables StayCharged AA Batteries. As far as I can tell, those are the same batteries previously marketed as 'Pre-Charged'. In other parts of the world, those are also marketed as 'Active Charge'. They are stlll available in either 'white top' (made in Japan) and 'black top' (made in China) versions.
- Amazon has combined the AA and AAA versions of those Duracell batteries into the same product page. So now I look like a fool who says the same things twice. Oh well...

I was only half-right when I boldly proclaimed that "Duracell Pre Charged AA are rebranded Sanyo eneloop cells" in my original review. It turns out that the first batch of Duracell AA cells I bought from Amazon are made in Japan, and those are identical to eneloop (both mechanically and electrically). But lately I bought some more Duracell AA from a warehouse club. Those are made in China, and they are identical to the Rayovac Hybrid.

Judging from similarity of technical specifications and physical shapes of (+) and (-) terminals, I am convinced that the Duracell Pre Charged AA is actually SANYO eneloop AA underneath a different wrapper. Therefore all the good things you heard about eneloop apply to Duracell 'Pre Charged', too.
My own testing has shown that the capacity of eneloop AA cell is slightly above the claimed 2000mAh, and it is able to retain at least 85% of its charge after 5 months in storage. The Rayovac Hybrid AA starts with slightly higher capacity at 2100mAh, but it 'only' retains 80% capacity after 5 months. For all practical applications, both are equally good. Just pick whichever brand (Sanyo, Rayovac, or Duracell) is on-sale, and you can't go wrong.
One small problem with the Duracell 'Pre Charged' cell is that: it looked too similar to the well-known 'Copper Top' alkaline cell. So there is a good chance that people may mistaken it for a disposable cell. Personally, I prefer the distinctive-looking white case of the eneloop cell.

Note that the Rayovac Hybrid AAA has an average capacity of about 780mAh (compared to about 830mAh for eneloop AAA), so is not as good a value.

Judging from similarity of technical specifications and physical shapes of (+) and (-) terminals, I am convinced that the Duracell Pre Charged NiMH cell is actually Sanyo Eneloop underneath a different wrapper. Therefore all the good things you heard about eneloop apply to Duracell 'Pre Charged', too.
My own testing has shown that the capacity of eneloop AAA cell is slightly above the claimed 800mAh. The Rayovac Hybrid AAA is usually cheaper, but its capacity is slightly below 800mAh. Both brands are able to retain at least 85% of their charge after three months of storage. Just pick whichever brand is on-sale, and you can't go wrong.

This is how batteries should be made! By Nuknuk
Pros:
-For a rechargeable battery, these batteries does not need to be charged before you use it for the first time; right from the packaging into your gadgets.
-They last a long time.
-Does not need special charger. You can use your existing NiMh charger.
Cons:
-You can confuse them with regular Duracells and mistakenly thrown away after losing charge.
-This later technology is still expensive.
I also like Eneloops by Sanyo. But they are not easily available at your local stores.
