Excerpt: Purchased for my Canon EOS Rebel Xsi. Sorry to say after charging for 12 hours and then trying again 2 days later, charging for 24 hours...this battery only holds 1/2 a charge. I am trying to return it now.
Excerpt: I had to buy this one because the original life ended because I leave the battery in camera and did not use it a few months.
Don´t leale your battery in camera when not in use for long time if you dont want to spend more than necessary.
