OK. So notice most of the complaints are about the shipping time not the quality of the product.

Ordered 3/26 received in two days with prime.

As others have mentioned these are 900mAh batteries.

Ran the 4 cells through a few charge-discharge cycles on a BC-900 charger (also a good product available here). All of the batteries tested above 900mAh. 902, 926, 928, and 937mAh. This is with only a few cycles on them so it might creep up later but should not be much.

This is better performance than less expensive brands (ultralast, etc.) Those seem to test at only about 50% of the cells above the stated capacity, although they are often at least 85% of listed capacity.

Just my experience, with a small sample size. Choose which is best for you.

Would be 5 stars but could be a bit less expensive. Only a minor complaint.

Update 8/2/06

Used these in a GPS unit and MP3 Player mainly. Probably have been recharged around 10x each. Retested now they are at 900, 924, 930, and 932. so not much change

I have begun to buy DuraCell over Energizer after having 4 of the latter go bad and refuse to charge after only about 20 cycles. In general NiMH are great, but they have some caveats people should know about.

1.) They don't hold a charge over long periods of time very well as their charge ebbs away just sitting around. So if you have something you really need to work on the rare occasion you use it, like a flashlight in the car, use Lithium(longest shelf-life) or Alkaline.

2.) NiMH only produce 1.2 volts, not the standard 1.5, so for a flashlight that uses 4 batteries it produces 80% of the voltage - 4.8 volts, not 6.0. LED lights in particular have voltage compensation circuits, but they use up a fair amount of energy, so unless your flashlight was designed for NiMH it will not be as bright and won't last as long as using Alkaline in most cases. What are your priorities?

3.) The greater a battery's capacity, (expressed in mAH, short for milli-Amp hours, where 1,000 mAH will provide 1 amp for 1 hour) the fewer recharge cycles you will get. Very high capacities require very thin and fragile materials. Again, what are your priorities?

4.) It still pays to charge NiMH batteries all the way up and then use them until they are completely dead before charging again. The Duracell charger I bought states explicitly that batteries may need to be charged and used 2-3 times before obtaining optimal performance. It gives them longer life and the ability to accept a fuller charge for life. It also "heals" batteries that have been habitually "topped off" and develop memory.

5.) 15 minute chargers are great if you really need the batteries fast, but even the 30 minute chargers really heat up the batteries, and that shortens their lifespan. In most cases it makes more sense to keep a spare set of batteries than to habitually flash charge them. I have also heard that when the charger indicates it's done, it's not. Leave them in another hour if you can. Leaving them in all the time tends to ruin them.

6.) NiMH really work well in applications where you will use up the entire battery's charge in less than a week, (or month at the outside) the application takes a lot of current/energy, and your use is habitual. They can also be a lot more environmentally friendly than throwing out tons of Alkaline batteries.

Amazon must be shipping a new batch. got them today and they were 900mAh and made in Japan. Good value compared to local shops.

Duracell is the best battery out there, especially the rechargables. I would swap Duracell with Energizers in my mp3 players every other time I needed to charge my batteries. My last set out-lasted Energizers hands down.

I was pleased that these weren't the 750 mAh batteries the whining reviewer got; although for the price, 750 mAh isn't a terrible thing, it's just not as great a deal as 900 mAh capacity for the same price.

Since they're from Duracell, and they were manufactured in Japan, you can be sure these batteries are top quality; I have no reason to believe that this is not the case (they arrived a couple of hours ago), but if they are anything but wonderful, I will update this review within 24 hours. We'll definintely know about the initial quality by then. Otherwise, if something goes wrong with these later, we will definitely update our review.

So unless you hear otherwise, rest assured that purchasing these batteries, especially if you get free shipping, is an absolute no-brainer if you need AAA size batteries...for anything. Flashlights, cameras, anything: 900mAh AAA NiMH Batteries are as good as it gets right now, and to get namebrand quality at this price is a treat (we paid <9 dollars shipped).

White Top batteries that are Made in Japan are the ones to buy. Black top Made in China do not last. I have 1 dozen Black Top batteries less than a year old that don't hold a charge for more than a day.

I bouget some duracell rechargeable AAA NiMH Batteries and I would not buy them again because the charge does not last very log.

Duracell DC2400B4N Rechargeable Batteries, NiMH, AAA Size, 4-Count Packages (Pack of 2)

PHOTOLAND WAS GREAT. FAST DELIVERY, AND I GIVE EM 6 STARS..

Perfect for my Vtech portable phones. Has alot of reserve power for long conversations on speaker phone

They don't last that long, maybe 6 months. In fact after 3 or 4 months they don't hold a charge for very long. That eventually gets worse. I bought another pack to test them again, but if I get the same results, I will switch, most likely. I am one of those who almost always puts the phone back on the hook and I have heard that wears out batteries quicker, don't know.

UPDATE: These last ones lasted only 2 months. I think I will go back to panasonic batteries. I keep buying these because they look pretty. But, they don't last. I'm not even sure 2 stars is low enough. I just changed it from 3. I tried, I really tried to give them a chance. I have a panasonic dect 6 phone I use them in and I have never had a problem with any other battery, just these duracell.

UPDATE: I ordered these September 2011, because of the good reviews, so we'll see: GP RECYKO ALWAYS READY NiMH Rechargeable battery package: 8 AA 2100 mAh + 8 AAA 850 mAh
