Battery disconnect

They work but they will spark when they make contact. Plus they have to be cranked pretty tight to work. Honestly buy a cable and an inexpensive surface mount marine battery switch and do it that way, I have used the kind you posted a link to on cars and do work but its not something I would want on a boat. If something happens where you need to shut off the battery quick you will be happy to have a real switch.
 
My 1985 Sedan Sportfisherman is in haul out as we speak. I had it surveyed and I have 2 of the batteries with wingnuts. The surveyor told me that it isn't done this way in a marine environment. Meaning, put the right bolts and nuts on it.
I agree with KP49.

How long do you plan on going between boating? A good battery should last weeks and weeks before you even begin to notice a difference. A better investment might be a small, solar trickle-charger.

Also, do you keep it in the water? If you do, and you have an automatic bilge, you'll want to make sure that it hooked up independently of any switch you install.

I am an auto electrical parts wholesaler. Used to she'll quite a few of them, probably still ave some on the shelf, don't think I have sold any though for a few years.

My honest opinion though as a tradesman, they are a cheap and nasty solution. I agree with the previous comment about sparking, and I wouldn't want it in a disconnected position if it was sitting in the water or being trailered, due to vibration and that issue.

Honestly if price is the issue, buy one of the small battery isolators with the red key, they don't cost much more that unit

I put a Sunsaver Duo on my 210 Select with a Power film 28 watt panel - that was more than enough to keep batteries in peak condition with 4-6 hours of sun pr. day. I could have done with a 14 watt without any problems. If you only have a single battery you can just use the Powerfilm battery charger they sell in their bundles. But the Sunsaver Duo supports 2 batteries.
