I bought this battery to power 2 12 inch Garmin Screens on my boat. One screen runs Live scope and the other does the more typical sonar and GPS work. I incorrectly connected the battery at one point and shorted it. I sent a note of to Norsk for help on what to do next. They responded quickly and I could tell the cared about getting me back up and running. We all know there’s only so many fishing days on the calendar!! Couldn’t be happier with the battery and the customer service.
