The battery life on the ContourROAM is about 2.5 to 3 hours on a full charge, depending on settings and conditions.
You can provide continuous power to the camera if you need to record for longer than that by using a Contour brand wall charger or the Contour brand car charger. Both are designed specifically to supply continuous power to the camera while also charging the internal battery.
There are available from your local Contour retailer. If you are in the USA, the chargers can be found at our online store here: http://store.contour.com/power-c2.aspx
