  OK Dave an' All; To clear it up, OFFSET post, I guess, yur right. Dyno
calls it a "wing nut" post in THEIR catalog. The new Trojans come through
with them, as well as that silly manafold type cap. Nice concept but they
LEAK acid whenyu charge the battery. Something yu do alot withEV's I don't
need pools of electrolite all around tops of the batteries. I won't back
down on saying the bolt is pretty useless, AND ads height to the battery,
albiet not much. Other Trojans come with "Duel Purpose "S" posts, an
automotive with a hole/ flat aide. OK ,the clamp type automotive terminals
don't care, grab that just fine.

 Guess whatever battery catalogue yur looking at, rather than a universal
definition. EVerybody agrees on "automotive" post, like the ones cars had
for YEARS, ICE's I mean. That's what my FIRST set of cells came with and I
didn't wanna redoo all my cables, etc to change batteries.

   Back to AC/DC and rolling backwards<G>!
