The ContourHD Spare Battery gives you the freedom to extend your recording time by having double the battery life. Take a spare one with you and enjoy double the time to record your adventures.
Simply charge this up and carry it with you when you head out for a full days recording. It is light and small enough to carry in your pocket or bag and is easily exchanged when the first one runs out of juice.
Each fully charged battery will give you approx 2hrs of power and takes about 3hrs to charge up again.
