Great value for Pre-Charged Batteries - with some caveats, October 22, 2008
The Kodak Pre-Charged AA NiMH belongs to the latest generation of low-self-discharge NiMH cells. It may not be as well-known as other brands (SANYO eneloop, Rayovac Hybrid, Duracell Pre Charged) but it is just as good according to my own testing:
1. The battery capacity is specified as 2100mAh. But the average capacity I have measured (using my La Crosse BC-900) is actually closer to 2200mAh!
2. After three months in storage, the capacity lost is only around 10%. This is even better than the results I got from eneloop and Hybrid (both close to 15%). Note that the difference could be due to measurement error and different ambient temperature, since those cells were not tested during the same period.
I have used more than a dozen of those Kodak Pre-Charged AA cells in digital camera (Canon S5), external flash (Canon 420EX), plus various toys and gadgets with great satisfaction. This Kodak 4-pack is an excellent buy, especially since it can be found at lower prices than other brands of pre-charged cells. If you are also looking for a fast and compact travel charger, then I highly recommend buying it with the KODAK K6200.
However, there are a few caveats when buying or using those Kodak Pre-Charged cells:
1. Make sure those cells are in WHITE cases. Avoid other Kodak rechargeable cells that come in green or grey cases, as those are not "Pre-Charged".
2. Those cells are slightly fatter than ordinary alkaline cells. Most appliances have no problem accepting them, except for my Microsoft wireless keyboard which has a very tight battery compartment. In this particular case, I have to use Hybrid AA cells since they are slimmer than others.
3. Many vendors here offer this product at a low price, but then charge you ridiculous amount in shipping and handling. If possible, wait for it to be available directly from Amazon, and order it with free "super-saver" delivery.

Great batteries, long life!, April 9, 2008
I found these at Wal-Mart for $8.47 in the camera section, if you happen to want some of these new pre-charged batteries right away.
If you are not familiar with the pre-charged batteries, these little things actually hold their charge similar to an alkaline battery, in fact they come charged right out of the package!
The problem with normal rechargeable batteries is that while they have a great capacity to store power, they lose most of their charge in manner of weeks. You really must have a freshly charged pair ready to go in your camera. A normal rechargeable is not suitable for things like remote controls, clocks, etc.
You can charge these batteries up and leave them charged for a year and still know that they will be charged and ready to go. You don't get this option with regular NiMH batteries. There really is no reason not to replace all your alkalines with these batteries now.
Update: (5/21/2008)
It's been over 1 1/2 months since I purchased these batteries, and they are still going strong in my Nikon SB-600 external flash. I haven't had to recharge them once, and this was right out of the package! I've probably gotten at least 200 flashes out of it and I'm very satisfied with the long life these batteries are going to provide me! I even hear these batteries get better the more you use them, yahoo! Again, I highly recommend these "Pre-charged" batteries for your high-demand digital equipment, and/or any device really!
Another Update (7/18/2008):
I continue to be amazed with these batteries. I am still using the same 4 batteries I purchased months ago in my high-drain flash unit for my camera. I haven't recharged or changed them yet! They are still going strong, and believe me, I've probably used this flash at least 1000 times since I put the batteries in. I'm beginning to wonder if these ever need recharging! :-)
Final Update (9/20/2008):
Ok so the batteries died the day after my last review, but they still lasted a LONG time!
I definitely have to agree with the another review posted here. The plastic label that surrounds the battery appears like it can easily be peeled away/loose. Nothing a dab of super glue can't fix, but definitely something you should consider.

Finally - a rechargeable NIMH that STAYS charged., October 26, 2008
Standard NIMH batteries have a nasty habit of self-discharging themselves. If you charge them up and leave them alone, they could be dead by the time you actually use them a few days or weeks later. This is especially true in hot climates. I've had NIMH batteries totally self-discharge in as little as three days in hot weather!
These Kodak pre-charged NIMH AA's are not like that. They keep their charge so you don't have to worry about whether the batteries you charged a few days or weeks ago will be dead when you need them. This also makes them suitable for low drain or intermittently used devices like remote controls, clocks, wireless keyboard and mice, and the like, where the self-discharge of a standard NIMH forces the user to charge more frequently than should be necessary.
There are a few issues with these batteries. One is they are slightly fatter than a typical AA battery, which makes it a tight fit in some devices. They also have less capacity than the highest capacity standard AA NIMH batteries. However these issues are pretty minor compared to the huge benefit of not having NIMH batteries which drain themselves flat in as little as a few days.
