I bought these batteries when I bought my new camera. After the first charge they worked about two weeks (which is great after using regular AA batteries). Once they ran down though I have not been able to get them to re-charge. So I only got about two weeks use out of them. I don't know if it is the batteries or the charger. I am very dissapointed!!
