I am not battery professional but I will tell you is that if you leave your unit hooked up and you do NOT have circuit breakers in your boat to turn off your unit will drain power even if it is turned off.  I am extremely surprised at how many of you guys leave your expensive units plugged in on your boats.  I did not spend spend roughly 4 grand on electronics to beat them up on the water and furthermore beat them up on the trailer ride home.  Just throwing it out there, I put my graphs on at the launch and put them back in my truck when I get back adding around 3 minutes extra per trip.  I also switched to a deep cycle battery for the cranking battery giving me 3 deep cycles but thats mainly in case another deep cycle fails but it can be beneficial.  I really do agree the units are probably draining the battery if they remain plugged in afterwards because just once I left my unit plugged in and didnt have the boat hooked up over night and my boat didnt start at the end of the trip...just lucky I was fishing in to the launch that night.  One more thing...not sure if its true but I heard that you are never supposed to hold power button down on HDS...I just made it a habit of pushing power button once and arrowing to power off.[/QUOTE]
