Timelapse with SX240
I completed a timelapse with an SX240. If you are planning one, these stats may be useful:
723 pictures at M1 (4000x3000) over 2:00 hours and 10s interval, completely drained a battery. This gives 30s of video played back at 24fps.

jpg 723 1,492,887,040 2,064,850.677731674
That's just under 2MB each. There were 7 pics per 1% of battery.
