[Public-List] Batteries

[gordon white]

    I am aware of the issue of a battery (or any shore power hookup) 
causing electrolysis of underwater fittings. There is a device that 
determines if your hookup is safe or not, and I tested with that years 
ago. I have been using a trickle charger of the automatic kind for 15+ 
years with no electrolysis of the underwater metal, and, my cheap 
charger is isolated. Some years ago the automotive chargers used an 
autotransformer to drop 110 volts AC to 12 volts, but what I now use 
does not. Obviously there is a question that you need to check out on 
any installation, but this works for me.
