The Odyssey ODS-AGM20L is a 12-volt absorbed glass mat (AGM) battery rated at 18 Ah, built for motorcycles, powersports vehicles and small cars. AGM construction makes it spill-proof and vibration-resistant, and Odyssey's thin-plate design gives it high cranking current for its size. It suits riders and owners who want a sealed, maintenance-free battery that tolerates cold and rough terrain. Against conventional flooded batteries it costs more and needs an AGM-compatible charger, but it resists sulfation better and holds charge longer in storage.
