-
The Motobatt 12V AGM Battery – MB10U is built for powersports riders who want reliable starts, long battery life, and zero maintenance. Whether you ride a motorcycle, ATV, UTV, or side-by-side, this battery delivers consistent performance in conditions where standard replacements often fall short.
What makes the MB10U different is Motobatt’s patented Quadflex technology. Using an innovative cell connection system, Quadflex maximizes unused internal space found in conventional batteries to support larger internal plates. Combined with increased grid thickness, denser paste, and more active material, this design delivers an ideal balance of amp-hour capacity and cold cranking amps. The result is up to 30% more capacity and power than same-size competitor batteries—providing stronger starts and improved voltage stability.
Key rider-focused benefits include:
-
Maintenance-free AGM design – fully sealed, factory activated, no acid to add
-
Ride-ready out of the box – ships pre-charged at over 12.5 volts
-
Superior durability – highly resistant to vibration and internal weld fatigue
-
Easy installation – solid-mounted terminals with threaded inserts for secure connections
Built with premium AGM (absorbed glass mat) construction, the MB10U is spill-proof and designed to handle harsh riding environments and frequent vibration. It requires no ongoing service beyond keeping it charged during storage.
If you’re looking for a high-performance 12V AGM powersports battery that delivers more power, greater reliability, and everyday convenience, the Motobatt MB10U is a confident upgrade that keeps you ready to ride.
