Default Re: Battery Tender Surge Protection

I just don't see much use for the battery tender in the first place.If you have a draw,then the tender is a band-aid,and the draw needs to be fixed.If you have a one wire alternator,you will have a draw,and really should have a cut off switch.I had a deltran tender go up in smoke a few years ago.Luckily it was on the top of an A engine,and it just kind of melted and smoked until the breaker blew.Any time a see a charger with the words,automatic,floating,or digital I run the other way.If it has lights that fade in and out,or change colors to tell you what it is doing I avoid them.A charger with plain switches,with a person to run and keep an eye on them,work just fine.If a car is just going to sit over the winter,I just unhook the battery and let it sit.If it is going to sit for more than a year I pull the battery and use it in something else.
