There appears to be no history of performance on these cells. Previous history of rechargeable alkalines from reputable manufacturers were a flop, at best.
I am amazed at the number of posts that represent complete ignorance of any knowledge about a commodity that we all use. There were only a couple of dozen posts that indicated some reasonable knowledge about cells and battery chemistry and characteristics. Google Battery University and do some research.
One post referred to buying quality alkaline primary (non-rechargeable) for 10-20 cents each, which I personally believe is a much more practical solution than the cells being sold here with extremely limited recharging tools (only the one sold with it), very limited cycles (about 25), decreasing capacity, and their likely hood of leaking (and ruining whatever it's used in or the charger).
Research and learn where rechargeable cells are practical and where they aren't. It's plain silly to put a $3 rechargeable cell in a TV remote where a moderate quality alkaline primary that costs 10 cents will last for 3 years.
For those interested in rechargeables, in plain terms, the LSD (low self discharge) NiMH cells are the way to go for the masses. The Eneloops that have had several references here are the creme of the crop, but pretty much all of the LSD cells have been good performers and certainly much better than all of the previous rechargeables. Those that have used the old NiCads and the more recent standard NiMH, but were disappointed and thought that recharging cells were more trouble than worth it, would likely be pleasantly surprised by the performance of the newest LSD cells. They are everything that you thought a rechargeable cell should be.
A quality charger is important. The LaCrosse 700 and 900 referred to are good chargers, but the creme of the crop is the Maha C9000 Wizard. Whatever charger you choose should be a true 'smart charger' and should have the ability to charge single cells (not in twos).
Avoid deep discharging your cells (unless intentionally doing so to condition them in a smart charger). Far better to recharge them often (top them off).
As to the comments about camera use .... agree with another poster, forget alkalines. NiMH are the perfect fit for digital cameras. The experienced photographer prefers higher capacity standard cells (2700-3000 mAh), but they usually know how to care for them. They have top quality chargers, will test and recondition them and make sure that they have several sets fully charged just prior to a shoot. For the rest of us, LSD are the way to go. A 2000 mAh cell that maintains 90-95% of its capacity for when you're ready to use it, is much more useful that a 2700mAh cell that has lost 50% of its charge just sitting in the camera.
There are some situations that primary cells are a better practical choice, especially with digital cameras. Backpacking or travel, etc. where weight and space are a premium, Energizer primary lithium cells are the way to go. They are best in temperature extremes (both hot and cold), are much lighter in weight than all other standard cells, almost never leak, even in extremes, and maintain 90% of their capacity for 15 years.
They are also my choice for important, stored flashlights, such as those in cars of garages, that are not used often, but must work when you need them.
In case you didn't get it from my first two sentences, buyer beware of the cells offered for sale here. The rest of my post is advice for alternatives.
