Title: Canon BP511A battery pack
Review: Canon BP511A 1390mAh Lithium Ion Battery Pack for Select Digital Cameras and CamcordersWhen I purchased my Canon 40D the first accessory I bought is this. One can never have enough batteries especially for a camera! I have learned from hard experience that 3rd party vendor batteries just do not work as well or as long as an original Canon battery pack.Which is why I only purchase Canon made battery packs. This one is no different than the other Canon battery packs I have purchased, holds a charge a long time and when in use gives me 1500-1800 photos per charge.
Is this product review negative?
