Moose..........do you still like the Optima Batteries

[aceoky]

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

Sorry I wasn't "unhappy", I was confused when you said "gell cell" and talked about the glass mats holding the lead in place (which both possess) .

It's "all good"
