From the photos in post #1 of this thread, the battery terminals (J3) seem to be about 2 inches apart and about 1/4 inch in diameter. The CT (computerized tomography) scan is an X-ray horizontal 'slice' at about the level of J3. The GSYuasa data sheet
http://www.s399157097.onlinehome.us/...s/LVP10-65.pdf for the LVP65 battery seems to suggest that each cell comprises six sub-cells (connected in parallel at top and bottom?) which appear as 'streaks'. The cell anodes and cathodes, I'm sure, are not connected to the cell case.
