How long does the battery last on the Canon FS100/FS10/FS11?

Question

The battery model is BP-808. If I record on the highest setting, how long would the battery life last?

Answer 1

Well, it all depends ...  if you are using the LCD screen or not, if you are leaving the camcorder on between recording segments or turning it off, how often you are using the zoom, and so on ...  

All these things create a heavy drain on the camcorder.  Most decent full sized camcorders come with batteries that have enough capacity to last up to 2 hours of constant recording with the LCD screen open but no use of the zoom - if the recording media can last that long.
