I have a trickle charger/ maintainer mounted in the boat & when I get back from an outing I just plug it into the house & let it go until next trip. I had no problems with doing that all summer. During winterization I removed the battery & the charger. Some people here said leave the charger on the battery in the garage & others said don't. What's the deal? Should I leave it on or not & why? Thanks, Maxx
