I am trying to find a source for some bronze battery cable adapters
that I originally purchased in San Diego several years ago.

The adapter resembles a small inverted "cup", with a 3/8" threaded
stud on the top. The "cup" fits over the vertical post on the
battery, and four 1/4" or 5/16" flat bottom bronze screws (which are
threaded into the sides of the "cup") are then tightened tightly
onto/into the battery post. The "cup" also has a grease zerk fitting,
into which grease is then injected into the area holding the battery
post captive. The battery cable lug (crimped and soldered onto the
battery cable) is then then slipped over the post and tightened with a
copper nut.

The result is a bulletproof system, and as there is no air at the
lead-to-bronze interface, corrosion is non-existant. I have had these
on my boat now for over 7 years with no problems.

If anyone has a source, it would be appreciated.
