A:Answer With a full charge, you can get through a 30-40 minute performance or program. If you record in burst you might make the battery last longer. Also, you can record and have the camera connected via the USB connection. If you choose to record for more than 10 minutes, about 8-9 minutes will record and the rest will continue with the next mp4 file. So the limit is around 10 minutes. I used a 128 Gig SD card for this camera, a regular one.
