Motobatt Battery MB16AU Sealed Factory‑Activated Replaces: YB16AL‑A2

OVERVIEW

The Motobatt MB16AU is a sealed, factory-activated AGM battery designed to deliver reliable starting power and stable electrical performance for demanding motorcycle applications. Constructing with advanced Absorbent Glass Mat chemistry, this unit serves as a direct drop-in replacement for the OEM Yuasa YB16AL-A2, offering enhanced durability and resistance to vibration. Engineered specifically for motorcycle compatibility, it installs instantly without assembly, fluid checking, or electrolyte addition to restore consistent ignition across street and touring platforms.

ENGINEERING & PERFORMANCE

Featuring 20.5 amp-hours and 230 cold cranking amps, the MB16AU provides aggressive cranking capability that ensures rapid engine ignition even in cold temperatures or after prolonged storage. The sealed AGM construction eliminates acid spill risks while the QuadFlex terminal architecture delivers four versatile connection points for precise cable routing and secure mounting. This maintenance-free design maintains stable voltage output for sensitive EFI systems and ECU memory retention, resisting internal sulfation and recovering quickly from deep discharge cycles under heavy electrical loads.
