I've got a nikon D3100 and i want to know how long of a video can a 16Gb SD memory card hold? + what's the battery's life?

Added (1). How many videos can i take if the length of a video was about 2 mins

It doesn't matter because the camera will only run for about 12-minutes anyway. That's because of heat buildup in the sensor that can damage it or other sensitive parts.

Besides if you're smart about video you'll be shooting for the editor not for length. If you're shooting an event you have to stop and restart about every 10-12 minutes.
