Motobatt 12V AGM Battery - MB16AU
The Motobatt 12V AGM Battery - MB16AU is built for powersports riders who need dependable starting power, long service life, and zero maintenance. Designed for motorcycles, ATVs, UTVs, and side-by-sides, this battery delivers a clear performance advantage over standard AGM replacements.
At the core of the MB16AU is Motobatt’s patented Quadflex technology, engineered to maximize both capacity and cold cranking power. By utilizing unused internal space found in conventional batteries, Quadflex supports larger internal plates without increasing the battery’s physical size. Combined with enhanced grid thickness, denser paste, and increased active material, this design delivers up to 30% more capacity and CCA than same-size competitor batteries. The result is stronger starts, improved voltage stability, and reliable performance in cold or high-demand conditions.
Built with premium AGM (absorbed glass mat) construction, the MB16AU is fully sealed, spill-proof, and highly resistant to vibration and internal weld fatigue. This makes it ideal for harsh riding environments where traditional batteries are prone to early failure. The battery is factory activated and maintenance-free, eliminating acid handling and setup time.
Shipping pre-charged at over 12.5 volts, the MB16AU is ready to install right out of the box. Solid-mounted terminals with threaded inserts ensure secure connections and long-term durability.
For riders seeking a high-performance 12V AGM powersports battery that delivers more power, greater safety, and hassle-free ownership, the Motobatt MB16AU is a confident upgrade built to keep you riding.
