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.

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.

I have been using these for a few months in my camera, Logitech Harmony remote, and in my Wii remotes and they have been great.

However, I was looking at batteries at Walmart today and noticed their new stock of Duracell Precharged batteries are being made in China and no longer have a white cap. They shoved the Japan made white cap batteries to the back of the shelf. This makes me think they are no longer Eneloops. I am a little nervous to buy another set of these as the only reason to make that switch in my opinion is to save money yet charge the consumer the same. This usually leads to an inferior product. The originals I have are made in Japan.

Anyway, maybe the battery review guru of Amazon will do a little comparison test of these new China made precharged batteries vs the Japan made batteries that seemed awfully similar to the Eneloops. I really hope the new version stands up to the old.

This is a great battery. It has total power similar to a good alkaline battery, and holds its charge for a year. Duracell calls them “pre-charged rechargeables,” and they are often called “Ultra Low Self-Discharge (ULSD)” rechargeables.

It’s the only rechargeable battery that works for “long-duration” uses, such as remote controls, thermostats, and other places where batteries have low drain for long periods of time. I’ve been buying and using these batteries for nearly a year now, with excellent results. I keep a spare set in my gym bag for my headlamp and GPS, and they always have power after sitting unused for months. That’s unlike other rechargeables which have invariably self-discharged by the time I need them.

The rule of thumb that I have heard and believe, is that if a battery is going to be stored or in use for over a month, ULSD rechargeables have more usable power than traditional rechargeables. Over the course of a month, a standard rechargeable loses at least 1/3 of its total power to self-discharge. These batteries potentially have fewer charge/discharge cycles before they start to degrade, but they need fewer charges because they don’t self-discharge. Overall, it’s a win for all my uses.

I’ll be buying these exclusively for the foreseeable future.

Anyone that uses a wireless controller with their console of choice will certainly tell you that rechargeable batteries are a must. They simply eat up disposable batteries at a rate that would quickly put anyone in the poor house. While some gamers may opt for console branded chargers, it seems smart to invest in a system like Duracell’s that you can use in other devices as well.

I have been using Duracell’s rechargeable NiMH AA batteries with my wireless controllers for well over a year and have been delighted with them. They recharge quickly and hold enough power to operate both of my controllers for well over 20 hours of actual gaming. Once a pair discharges, I swap them out with another. Using this method, I have never run into an instance where I didn’t have a fully charged set at the ready.

These batteries work so well that I decided to also use them in all my remote controls. Despite heavy daily usage, I haven’t had one run out of power in over a year. These are certainly rechargeable batteries that any gamer can trust.
