Customer Reviews

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.

Much better than Energizer
These batteries are great. The new 'precharged' technology is great where it can sit unused for a year and still have most of its charge unlike the older rechargeable technologies. These 800 mAh actually last longer in my noise canceling headphones then the 1000 mAh (non-precharged) of the same brand.

I had previously purchased Energizer rechargeable batteries and found that after only a couple of weeks of non-use they would be dead.. so every time you went to use them they would be useless. After getting these Duracells and also some PowerEx batteries, I realize that the Energizer batteries are cheap Chinese junk. oh, the duracells are made in Japan and are very nice quality.

Anyway I definatly would recommend the precharged Duracells to anyone.

This is how batteries should be made!
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. I use it on my portable speakers which has been playing in loud volume for many weeks.
-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 got them on sale from Safeway for 11$ Normally sold at 14.99$

I also like Eneloops by Sanyo. But they are not easily available at your local stores.
