Motobatt 12V AGM Battery - MB51814
The Motobatt 12V AGM Battery – MB51814 is engineered for powersports owners who demand reliable starts, consistent performance, and zero maintenance. Designed for ATVs, UTVs, side-by-sides, motorcycles, and snowmobiles, this high-performance battery delivers a clear upgrade over standard AGM replacements.
At the core of the MB51814 is Motobatt’s patented Quadflex technology, which maximizes unused internal space found in traditional batteries. This innovative cell connection system allows for larger internal plates, thicker grids, denser paste, and increased active material—all without increasing the battery’s external size. The result is an optimized balance between ampere hours and cold cranking amps, delivering up to 30% more capacity and power than same-size competitor batteries. You’ll notice stronger starts, improved voltage stability, and better performance in cold or high-demand conditions.
Built with premium AGM (absorbed glass mat) construction, the MB51814 is fully sealed, spill-proof, and highly resistant to vibration and internal weld fatigue. This durability makes it ideal for rough terrain and harsh riding environments. The battery is factory activated and maintenance-free, eliminating acid handling and setup time.
Shipping pre-charged at over 12.5 volts, the MB51814 is ready to install right out of the box. Solid-mounted terminals with threaded inserts ensure secure connections and long-term reliability. If you’re looking for a high-performance 12V AGM powersports battery that delivers power, durability, and worry-free ownership, the Motobatt MB51814 is a confident, ride-ready choice.
