Ideal for the most advanced, high-drain devices, like digital cameras
Rating: - Good Rechargeable battery
Overall works very well. Holds charge well. Gets 20 or so full recharge/drain cycles before starting to taper off on holding a charge. 30 or so is the limit. However, that's not a bad return on investment.
Rating: - Dead
I have a whole bunch of these along with a lot of other rechargeable batteries and these ones are the worst by far. They only work for about 15 minutes now and then die. It's takes probably a year to get to this point. I could have saved money by buying regular batteries for the amount of use I've gotten out of these.
Rating: - Very short lifetime
The lifetime of those batteries are so short you would need dozens and overwhelming look after for continuous recharge. Not money worthy.
Rating: - Don't waste your money
As others have said, these batteries do not hold a charge at all. I have 20~ of these that I mostly use in Wii and Xbox 360 controllers, with 6-8 to spare for when one set goes dead. They're always charged as soon as they're taken out and then put back in a case with the other reserves. Often times it might be 3-4 weeks before I have to change some out, and at least 1/2 of the time the replacements are already dead.
I have 4 Sony batteries in the mix, and as another poster has mentioned, I've also noticed that they seem to hold their charge much better.
