About one hour of use with the standard BP-809.
The Canon BP-819 extended life battery does work in the WP-V1 but I have not verified usage time yet. It is supposed to be about 2 hours of use.
I have read somewhere that other brands of extended life batteries will not fit in the WP-V1. I read it somewhere, but cannot verify that it is true.
I posted it. I contacted a Canon rep and they emailed me what patteries would work with the WP-V1.
