Not at all necessary to disconnect battery. My charger/maintainer is always hooked up while the boat is in the garage. I'm always out there doing something with the stereo running.

In my mind, I was thinking that this would/could keep at little charge going to the ECM, the starter and other electrical components during the off season and possibly cause an earlier failure than not having them connected. Am I over thinking it?
Those electrical items are connected to the battery for the other 8 months of the season with no failure. So no damage would be caused by having them connected to the battery during the off season. The key is to use a charger that does not put out too high of a voltage level while charging. That can damage those electrical components as well as over charge a battery.

I use a Battery Tender Jr and leave the leeds on the battery all the time.

I leave mine hooked up when not in use. It's so low amps it won't hurt a thing. Also it will keep your batteries fresh

Add a Perko switch and you will have no worries. When you are done boating move switch to off and plug in your tender.

I have been using this Diehard charger for a couple of years now and have loved it. It analyzes your battery when you first hook it up. Then it will show you percent of charge until the battery is fully charged. I leave it hooked up to a garage queen car 24/7. It has worked great.

Hoping someone could answer me a quick question. Would a stock 96 Prostar have 4 gauge or 2 gauge battery cables? At the auto parts store trying to buy some new connectors.

I recommend the Guest 16102 Marine Battery Charger (12-Amp) for maintaining batteries during the off season. A very nice product and has maintained my battery for years.
