Motobatt 12V AGM Battery - MB5U
The Motobatt 12V AGM Battery – MB5U is a dependable upgrade for riders who want stronger starts, longer service life, and zero maintenance from their powersports battery. Designed for motorcycles, ATVs, UTVs, and other small powersports vehicles, the MB5U delivers consistent performance where standard batteries often fall short.
Motobatt’s patented Quadflex technology is the key advantage. By utilizing unused internal space found in conventional batteries, Quadflex allows for larger internal plates and an optimized balance between amp-hour capacity and cold cranking amps. Enhanced grid thickness, denser paste, and increased active material help this battery deliver up to 30% more capacity and power than same-size competitor batteries.
Built with premium AGM (absorbed glass mat) construction, the MB5U is fully sealed, spill-proof, and highly resistant to vibration and internal weld fatigue. It’s factory activated and maintenance-free, with no acid to add and no setup required. Shipping pre-charged at over 12.5 volts, the battery is ready to install right out of the box. Solid-mounted terminals with threaded inserts ensure secure, long-lasting connections.
For riders seeking a reliable 12V AGM powersports battery that combines performance, durability, and convenience, the Motobatt MB5U is a smart, ride-ready choice.
