Lesson Learned.
I had a Yellow top Optima. I cut the top posts to fit my battery
compartment and shortly after that the battery lost power and would not
accept a charge.

I got the battery back into operation. It seems the inner plug of the top
posts connect to the cells. The outer ring of the top posts connect only to
the side posts which were my connect points to distribution.

By drilling and tapping a quarter/32 screw into those flush cut inner plugs,
I regained access to the cells. The battery is now taking a charge just
fine. Cutting the top posts also improperly vents the interior, so that was
sealed up with some epoxy. It has a new home as drive source to a trolling
motor, and a pair of Odyssey 925s is going in the airplane.

Good data sir. Thanks for sharing. I'll take this opportunity
to reinforce the notion that there is as much value in
sharing ideas that do not work as there is for sharing
the ones that do work. If you can help another builder avoid
repeating an experiment with a predictably poor outcome, the
$time$ you expended "getting behind" will push him ahead by
the same amount of $time$. If more than one builder benefits
from the information, then the service you've provided becomes
still more valuable.
