 No, the gel is your glass mat battery. The original ones, like the Optima battery, is a gel-style battery. Oh, so I've just heard of an AGM or a glass mat. I haven't ever heard of them called gel. That's interesting. Look, I learned something else today. Right, and now we have another new one in there with Clarius, and that's the lithium batteries, which is a totally different way of maintaining and charging with the lithium battery.
