An eneloop by any other name...
[Updated Dec 21 2008]
I was only half-right when I boldly proclaimed that "Duracell Pre Charged AAA are rebranded Sanyo eneloop cells" in my original review. It turns out that the first batch of Duracell AAA 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 AAA from a warehouse club. Those are made in China and they are identical to the Rayovac Hybrid (see my scan in the Customer Images section). 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.
[Original review follows]
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.
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.

New Duracell 'Value Charger' is a _slightly_ better value nowThis package (Duracell Pre Charged Rechargeable Nimh Batteries Combo) contains the Duracell CEF14NC 'Value Charger' four Duracell DX1500 Pre Charged AA cells (2000mAh) and four DX2400 AAA cells (800mAh).
Duracell pre charged cells are either rebranded Sanyo eneloop ('white top') or Rayovac Hybrid ('black top'). But there is no way to know which version you are going to receive. Incidentally I have examined dozens of those packages in a famous warehouse club. Majority of them contain AA 'black top' cells with just a few containing 'white top'. All AAA cells are 'black top' only.
The new Duracell 'Value Charger' offers several improvements over the previous version (which was also called 'CEF14NC'):
- It accepts 100-240V universal AC input (instead of just 120V AC)
- It can charge up to 4 AAA cells (instead of just 2 AAA)
The charging current is same as before: 360mA when charging AA cells 180mA for AAA cells. That means it take about 6-7 hours to recharge a pair of exhausted AA cells.
One remaining drawback with this charger is that it still charges in pairs. That is either 2 or 4 cells. This is very inconvenient when you have appliance that requires either 1 or 3 cells. Now you're left with one cell that you cannot charge. If you try to charge one exhausted cell together with one that is full then the second cell will be over-charged (becuase the charger only stops when the combined voltage of two cells is high enough). NiMH cells are fairly robust so they are unlikely to burst or leak when over-charged occasionally. But over-charging is very bad for battery lifespan in the long run.
If all of your battery-operated appliances require only even number of cells then this package is still a good value. But if you do need to charge odd number of cells occasionally then I recommend buying the Sanyo Eneloop 2 Pack AA NiMH Pre-Charged Rechargeable Batteries w/ Charger in addition to this one. It contains a compact charger 'MDR02' that can handle 1-2 cells and it recharges much faster.
