Motobatt 12V AGM Battery - MBT9B-4
The Motobatt 12V AGM Battery – MBT9B-4 is built for powersports riders who demand reliable starting power, long service life, and zero maintenance. Designed as a premium replacement for motorcycles, ATVs, UTVs, and side-by-sides, this battery delivers consistent performance where standard batteries often fall short.
At the heart of the MBT9B-4 is Motobatt’s patented Quadflex technology. Using an innovative cell connection system, Quadflex maximizes unused internal space found in conventional batteries, allowing for larger internal plates without increasing the battery’s external size. Thicker grids, denser paste, and increased active material work together to provide an optimal balance between amp-hour capacity and cold cranking amps. The result is up to 30% more capacity and power compared to same-size competitor batteries—especially noticeable during cold starts and high-demand riding conditions.
Built with premium AGM (absorbed glass mat) construction, the MBT9B-4 is fully sealed, spill-proof, and extremely resistant to vibration and internal weld fatigue. This makes it an excellent choice for rough terrain and high-vibration environments common in powersports use. The battery is factory activated and maintenance-free, eliminating the need to add acid or perform initial setup.
Shipping pre-charged at over 12.5 volts, the MBT9B-4 is ready to install right out of the box. Improved solid-mounted terminals with threaded inserts ensure secure connections and long-term reliability.
For riders looking for a high-performance 12V AGM powersports battery that offers more power, greater durability, and worry-free ownership, the Motobatt MBT9B-4 is a smart, confidence-inspiring upgrade.
