Title: This batteries are completely worthless!!!
Review: Purchased two of this batteries in September of 2007. They worked fine for a while. Stored them fully charged for about 3 months. When i tried to use them again both batteries had fully discharged, after charging them they each ran for about one minute each and died. Tried to recharge them but they wouldn't hold a charge no matter how many times or how long i put them on the charger. By comparison the original battery from canon only lost about one quarter of its charge in three months and is working the same as new. DON'T BUY THIS PRODUCT, they are unreliable. You wouldn't want to miss videotaping an important event due to battery failure.
Is the review positive or negative?
