Absorbed Glass Mat
AGM batteries differ from flooded lead acid batteries in that the electrolyte is held in the glass mats, as opposed to freely flooding the plates. Very thin glass fibers are woven into a mat to increase surface area enough to hold sufficient electrolyte on the cells for their lifetime. The fibers that compose the fine glass mat do not absorb nor are affected by the acidic electrolyte. These mats are wrung out 2–5% after being soaked in acids, prior to manufacture completion and sealing.
The plates in an AGM battery may be any shape. Some are flat, others are bent or rolled. AGM batteries, both deep cycle and starting, are built in a rectangular case to BCI battery code specifications.

Famous quotes containing the words absorbed, glass and/or mat:
“Sternly, remorselessly, fate guides each of us; only at the beginning, when we’re absorbed in details, in all sorts of nonsense, in ourselves, are we unaware of its harsh hand.”

“Heaven has a Sea of Glass on which angels go sliding every afternoon. There are many golden streets, but the principal thoroughfares are Amen Street and Hallelujah Avenue, which intersect in front of the Throne. These streets play tunes when walked on, and all shoes have songs in them.”
—For the State of Florida, U.S. public relief program (1935-1943)
“Or on the Mat devoutly kneeling
Would lift her Eyes up to the Ceiling,
And heave her Bosom unaware
For neighb’ring Beaux to see it bare.”
