Yuasa Batteries: The Industry Standard in Powersports Power

When it comes to powersports and vehicle batteries, few names carry the weight of Yuasa. Yuasa Battery, Inc. has been manufacturing batteries in the United States to uncompromisingly high standards since 1979, earning a reputation as the dominant force in powersports energy storage. Today, the brand supplies more OEM partners than all of its competitors combined — a distinction earned through decades of engineering innovation and real-world reliability across motorcycles, ATVs, UTVs, snowmobiles, personal watercraft, and scooters.

A Legacy Built on Innovation

Yuasa's technology leadership in this category is well documented. In 1983, Yuasa pioneered the world's first motorcycle maintenance-free AGM batteries with the YT Series. Then in 1988, the landmark YTX Series arrived and quickly became — and remains — the industry's de-facto standard for AGM powersports batteries globally. Innovation continued with the 1999 introduction of the YTZ Series, the first global Factory Activated (FA) battery design, delivering high cold-cranking amps in a compact, lightweight package. In 2008, Yuasa raised the bar again with the GYZ Series — their most powerful and toughest battery lineup, engineered specifically with the American rider in mind and serving as Yuasa's second US Factory Activated design.

Yuasa Battery Product Lines Explained

Understanding the differences between Yuasa's core battery families helps riders and technicians choose the right fit for their machine:

• GYZ Series: Yuasa's elite performer — offering more cranking amps and higher amp-hour capacity for years of trustworthy service. Ideal for high-demand machines.
• YTZ Series: A compact, high-performance AGM battery delivering huge power in a small, lightweight package. Excellent vibration resistance and a corrosion-resistant design make it a standout for sport bikes and modern machines.
• YTX Series: The backbone of Yuasa's lineup and the global de-facto standard for AGM powersports batteries. Virtually maintenance-free, the YTX uses an advanced lead-calcium design that holds its specific gravity more than three times longer than conventional lead-antimony types.
• YuMicron & YuMicron CX Series: Premium conventional batteries for applications that don't require AGM. The YuMicron CX was the first small-engine starting battery to use lead-calcium technology, generating 5–8% more cold-cranking amperage than standard lead-antimony designs.

Why AGM Technology Sets Yuasa Apart

Yuasa's Absorbed Glass Mat (AGM) batteries are built around a sealed, non-spillable architecture that eliminates water loss entirely. All of the acid is absorbed into special plates and separators, meaning there's no risk of harmful acid leaks — a critical advantage for ATVs, watercraft, and motorcycles that operate on uneven terrain or extreme angles. These batteries are also engineered to withstand severe vibration through compounded case materials and through-partition construction, which delivers shorter current paths and maximum cranking power. Many models are available as Factory Activated — pre-charged and ready to install straight out of the box.

OEM Trust, Rider Confidence

Over 80% of major OEMs rely on Yuasa for their batteries, and it's easy to understand why. Yuasa batteries are manufactured at their Laureldale, Pennsylvania facility, where a relentless focus on AGM technology advancement ensures each unit meets or exceeds OEM specifications. Whether you're replacing the battery on a Harley-Davidson cruiser, a Honda ATV, a Yamaha WaveRunner, or a BRP Sea-Doo, Yuasa has a purpose-matched solution with the engineering pedigree to back it up.
