I've had a Meike MK-80N3 intervalometer for a few years. It works great, but when doing time lapse with long exposures (1 min) I find the watch battery running out quite quickly. I always have to have a few packs of Energizer 2032 batteries with me. My guess is because it's draining energy while holding the shutter open?
Are there any intervalometers that fair better for multiple long exposures?
Thanks for any guidance.
