Hello there,

I am from Canada and I have summertime toys that I have put away for
the winter months. My problems are for maintaining battery
charge..........I have on a very heavily built shelf 3 deep cycle 12 volt
batteries out of my Boat and Rv trailer. Two regular 12 volt batteries out
of my Corvette and Boat motor starter battery....smaller 12 volt garden
tractor battery and also smaller12 volt battery out of my ATV
quad...amongst a few others that are out of other summer toys.

Do they make such a thing that I can wire the whole works up ...plug
in for the winter and walk away til spring?

thanks for any replies....Jim


The key as another poster recommended is charging the batteries with
isolation diodes. You cannot use just any diode because it will drop a half
volt or so and never charge the batteries properly...here are a couple of
links to help you out.....and best of luck on your project...Ross
