The battery tender will be great to keep the battery in fully charged trim. I would use it if the boat is not used for a two week period. In time you will need to get into the battery box to clean and secure the connections, it is just one of many things a skipper has to do. I would use the Battery Tender the night before a trip, if you hard wire the quick disconnect make sure you keep the connector dry and salt free. Nothing mess's up a trip more than a outboard that wont start at the ramp, while all the New Yorker,Conn and Canadian snow birds stand there in black socks, Bermuda shorts and street shoes, point and tell each other dumb shite like ''he flooded it''.
Do you need a jump start ? Do all your maintenance well, back in your drive way. When you hit the ramp with your A team crew your on a mission to kill.... fish of course.
