An AGM battery is a special highperformance battery design that absorbs the electrolyte into a fibrous mat material woven between the lead plates. There is only enough liquid suspended in this spongelike material to keep the mat moist. If the battery were broken open, acid will not gush out. This is why they are sometimes called Dry Cell ...Get Price
