There are significantly more plates and plate surface than optima spiral gel cells. Reserve hours are 2x that of same size optima.

According to what inforamtion I got with my Optima, (when buying it)......Optima batteries are "spiral cell technology" Not "gell cell" batteries at all????



Couple of sites to check IMHO
