[C320-list] 4D Battery replacement

[Chris Burti]

HI John,
We are still running the same set that we had purchased and discussed back
then, but will probably replace this year in an abundance of caution. They
are an exact size replacement for the OEM Exide Nautilus 4D's that came on
the boat and fit perfectly. They are a heavy truck commercial duty battery
and spec out almost identically with deep cycle batteries.

I may go with two 6v batteries this time for the additional amp hours and
the fact that installing and removing the 4D's has prudently become a two
person job for me now. I have a pair of stainless battery trays that I had
fabricated to fit the slightly greater length needed  for the conversion
and will just need to rewire the jumpers, the alternator feed and the
charger feed.
