Now with NiMH rechargeables and more sophisticated chargers, it's a no brainer to convert over to this newer technology. High drain devices like digital cameras are a great example of where NiMH really shine. I take picture after picture with flash and review photos on the built in LCD and I don't worry about these duracells running out. 1,800 milliamps will last a long time.
For trips/outings where I'll be taking hundreds of shots, I just get an extra set that I can charge and have ready. No more wasting money on disposable batteries! Some travel chargers are really small, and you don't have to wait for it to charge overnight anymore, they charge in a few hours now.
For other devices that use AAA's like FRS radios, the smaller version of these duracells will take a beating and you will save lots of money compared to buying disposable batteries. I used these to replace the batteries for my Archos Jukebox mp3 player. They last about 2.5 hours longer than the batteries it came with and recharge in my jukebox without any problems.
These batteries come CHARGED (some don't). Got a second set just a few days ago.
First set is excellent, they seem to perform far beyond their spec. I use them in external flash for photography and they last aaaa llooot longer then any battery that I've ever used (excluding non-rechargeable Duracell), used them for over 8 months too ... charged at least once a week, they still seem to go strong (though I rarely fully drain them, that's usually good to keep the battery in shape).
Used Energizer as well ... but they didn't seem to last as long (granted only used one kind and tried a few Duracells before settling on these).
Also, I don't use Duracell charger, it's some crappy no name charger that came with some other crappy no name batteries I started with, but they don't last long enough in photo flashes, so I retired them.
I'm not going to talk about benefits of rechargeable, if you haven't gotten on board with using rechargeable, get over it, single use batteries are so 1990ssolid performance, and last very long, standby time is excellent too. I had some older version of this, which went bad after about 100 charges, I hope this one will last a little longer. Anyway, amazon had the right price and i will buy again. The batteries hold a charge well. It was nice to find rechargeable batteries at a reasonable price. I would purchase the product again! I bought this battery rechargeable Duracell and believe me it was the best investment I've made, is a battery that gives a high yield, as I use a Minolta 4000 AF flash, which is major consumer of battery charge and another that I have Vivitar 285HV brand, also good consumer of energy, besides the also use a Canon A1200, and was working properly, the above is that I have given 5 stars for the best quality, just give it 5 stars to shipping , which they did before the estimated time. Have never had any problem with duracell recharables. Bought them to use in the Wii remotes as we were going thru to many regular batteriesI user rechargeable batteries for just about everything, and these Duracell have proven to be very good. They last a long time and perform very well while they have a charge. When they finally wear out, I put them in the charger, and they are ready to go back to work. I am not sure how well that maintain a charge yet, but just wanted to let you know the listing accurately points out these are now 2450 mAh. I have used 2300 mAH Duracell rechargeables for a long time, but now even higher capacity 2650s are amazingly long-lasting. Good for just about everything that needs AA batteries, including demanding devices if you do the proper things for initializing and charging the batteries.. that is. One thing most people don't understand about rechargeable batteries is that they need EXCELLENT CHARGERS to ASSURE EXCELLENT RESULTS! Don't use the cheap chargers that come with cheap lowered-capacity batteries. They will quickly ruin your expensive batteries by boiling them with too high charge currents and not multi-stage charge curves. Don't use chargers that group batteries in twos or fours so that it doesn't charge single batteries, it shows you that it isn't sensitive to the small differences internally present in every battery--differences that get worse over time and can cause premature battery failure if your charger is taking the same approach to charging every battery! Get an expensive recharger like those made by PowerEx or Maha that scientifically charge the batteries using sensors which are monitored by a computer processor running sophisticated charging programs which account for the actual capacity of the individual battery. Many rechargeable batteries of friends that used bad chargers were almost ruined but a sophisticated charger refreshed them and brought them back to life! I am still using the same rechargeable Duracell batteries I bought over two years ago and I use them every day! They have lasted hundreds of charges because the charger is careful to pay attention to each individual batteries needs.
