Absorbed Glass Mat (AGM) Technology is an advanced battery design used in Yuasa's Maintenance Free Batteries that eliminates water loss. Once it's filled with acid the battery is permanently sealed - so you'll never need to fill it with water or check the acid level. Because of its lead calcium design, the AGM battery will hold its specific gravity more than three times longer than conventional lead antimony types. This means much longer periods between charges when the battery is used in a standby mode, like winter storage. And to remain factory-fresh the AGM battery is shipped dry along with its own pack of high-gravity acid that's added at the time of installation. Once filled with acid from its special packs, the AGM battery is virtually maintenance free. It's totally sealed and all of the acid is absorbed in the special plates and separators, so there is no need to worry about acid leaks on valuable vehicle parts and accessories.
These features are built into our conventional manifold vented battery - and every battery in the YUASA line: -Patented separators provide high cranking power -Through-partition construction delivers maximum power. -Unique sealed posts resist corrosion for longer battery life. -Polypropylene cover and container thwart damage from gas, oil, and impact. -Heat-sealed, bonded unit fabrication protects against seepage and corrosion.
Additional plates inside the battery provide up to 30% more power (cranking amps) than the YuMicron battery.
Customer fills battery from included acid tubes to create a sealed, spill-proof battery.
Never needs refilling.
High level of power (cranking amps) possible for today’s big bikes.
