If you need a replacement battery for your Canon video camera that allows you to see all your camera's features, this is the recommended Canon battery. They are expensive, but they are better than the generic variety. You also know how much battery power is available on your video display. Generics won't do that, but generic brands are a lot cheaper.
I prefer to buy the Canon battery pack that any other brand name for my Canon video Camera. The life of the battery is much better. I recommend to expend a little more for the original products. I bough before several other Chinese copies and they are in the trash.
