I bought a Canon SX230HS camera for a European vacation.It has excellent reviews but battery life is one area where it's been criticized so I decided to purchase a backup before leaving. I decided against a generic battery after reading that although they're cheaper, they don't hold as good of a charge as a Canon. I purchased one from ANATOLIAN BOOKSTORE, INC. through Amazon because that was the best price I found and I was very pleased that the battery was indeed an authentic Canon and holds the same charge as the one that came with the camera.It was delivered promptly, at a good price and was as advertised. I would buy from this vendor again.
