So I have a small boat and I want a small 12v battery to power my fish finder. I am going to purchase a Garmin 7cv. Would like to use one of the small 12v batteries, but I am unsure of how much power to finder will draw. It says 500w rms/4000 peak. How many amp/hour would I need to power the finder all day? 8ah? 15ah?
