should i buy Duracell Rechargeables StayCharged AA Batteries reviews

he 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.

[Original review follows]

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. Nice product, nice price, the batteries have more duration than my old batteries...i have two charges and the duration are the same. These are 800 Milli-amp hr batteries. If I had known, I would have bought locally. The price seems cheaper but they are the low grade batteries so you are not saving any money. Produce arrived quickly. Use to power Bose headphones and battery power source works as promised. Have not recharged batteries as yet but anticipate no problems. I always buy Duracell, they last really long time. Rechargeables are particularly good for house phones. The order was shipped promptly and on time. I received the newer 2450mah batteries, so the performance has been great.
I've had them in my Microsoft Mobile Mouse 6000 for a month and they are still working. well is just a battery,,, a really good one. need to say more?
(well for the sake of this review i will)I love these batteries so much that we are no longer using disposable batteries. They are great for the environment and easy on the wallet! I use these batteries for a laser pointer, as a toy for my cat! I shine the light around for her to chase (like a bug!) and have used it for hours per day. Before I bought the duracell, I went through batteries like crazy but these batteries are truly long lasting. You won't be disappointedThey've been on my arctic mouse since day i received them and haven't died just yet, there definitely better then regular batteries!
