GH1 Battery

How long does it take for the battery to go out of power
in video mode ?

The USA manual says 120 minutes, they do charge fairly quick, I think in about 3 hours. B&H sells batteries for $69.95 each.

Subject to additional real-world testing. Refer to Panasonic's global website (first few paragraphs):

The "120-min." rating is in reference to the GH1 recording in a specific video mode and with specific caveats; refer to link above, and:

Kholi has reported that he's getting good life out of the GH1 battery he's using, but in general, when it comes to _any_ cam's battery life, YMWDV*

* Your mileage will definitely vary! :)

Yeah I am getting really good battery life. Between two I've never run out of juice to shoot.

Definitely suggest two, maybe even a third just in case.
