The Canon BP-110 Battery Pack is compatible with Vixia HF R20, R21 and R200 high-definition camcorders. (It's also compatible with Canon Legria models HF R26, R28 and R206.) The BP-110 ships with those camcorders, so this is a replacement or additional camcorder battery.
The lithium-ion BP-110 is rated to power the camcorder for up to 85 minutes while it's recording in LP mode. It's an intelligent battery system, which means it communicates its charge level to the camera so that it can be displayed in the LCD screen.

Primarily for doing video work for family etc.
tried cheeper alternative battery, besides not being able to see how much battery life was left battery failure with contacts not making connection after second use. Buy the exact replacement for accurate level reading and quality the first time would have saved money and worked properly when needed without loosing recording.
