It’ll only marginally outlast a video because the camera is still working hard to do the intervals automatically so it may be best to hook up an external supply if it’s possible. There’s nothing worse than doing a time lapse and it ending up as incomplete.
This article might helps you. There is a Time Lapse calculator embedded into it, so you will be able to work out how long your finished time lapse will be based on the interval you set, and duration of the task. I hope it helps.
