What is an AGM battery?

Does Interstate sell one?

Thanks......just trying to learn about the various batteries here.

Yep .... Interstate sells them.

The last 12 volt Group 29/31 model showing at the bottom on this Interstate AGM battery list link is what we have two of in our Class C motorhome. They've just passed seven (7) years old now in our rig. I dust them off once a year for "maintenance". They get along just fine off the motorhome's stock 13.8 volt converter and the main engine's alternator:

A short time ago today on the radio, there was an ad for the Interstate AGM battery. I paid particular attention to the wording of the Interstate ad when they stated; it lasts two to three times longer than a regular battery. If their claim is true, then wouldn't that be a bargain versus the regular batteries?
