Title: Great Product- Long Life
Review: I have been professionally using my Canon 30D for over 1 1/2 years now, and the battery still works great! I have no problems shooting an entire wedding with it. I just purchased a second BP-511A, simply because I know that it's getting older and I needed a backup. It is really worth it to buy the Canon brand- its more than just a name when it comes to this battery.
