Motobatt 12V AGM Battery - MB5.5U

When dependable starting power matters, the Motobatt 12V AGM Battery – MB5.5U delivers a clear advantage for powersports riders who refuse to settle for ordinary performance. Designed for motorcycles, ATVs, UTVs, and snowmobiles, this battery is built to handle demanding conditions while providing consistent, reliable power.

The MB5.5U is powered by Motobatt’s patented Quadflex technology, an innovative design that maximizes unused internal space found in conventional batteries. By allowing for larger internal plates and an improved balance between ampere hours and cold cranking amps, Quadflex delivers up to 30% more capacity and power than same-size competitor batteries. Enhanced grid thickness, denser paste, and increased active material translate into stronger starts and better performance in cold weather or high electrical demand situations.

Built with premium AGM (absorbed glass mat) construction, this battery is fully sealed, spill-proof, and extremely resistant to vibration and internal weld fatigue—ideal for off-road and high-vibration environments. The maintenance-free design means there’s no acid to add and no setup required beyond installation.

Shipping factory activated and pre-charged to over 12.5 volts, the MB5.5U 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 combines power, durability, and everyday convenience, the Motobatt MB5.5U is a confident upgrade built to keep you riding without interruption.
