Summary: I lost my original battery, thus I purchased this one instead of the original one from the Canon website. I am not a professional photographer, but I am a graphic designer that I am taking photos a lot. I do not see the difference between the original one and this one. I will definitely buy another one again for extra.
Excerpt: I use Canon T5i cameras as backup cameras for wedding video shoots. I've tried 3rd party/generic battery packs and they just don't hold a charge as long and don't last more than a few months. Authentic Canon batteries just work. They last. They are reliable. Exactly what I need for critical wedding shoots.
