Motobatt 12V AGM Battery - MBT12B4
The Motobatt 12V AGM Battery – MBT12B4 is engineered for powersports owners who want reliable starts, longer battery life, and zero maintenance. Whether you ride a motorcycle, ATV, UTV, or side-by-side, this high-performance battery is designed to outperform standard OEM replacements in real-world riding conditions.
What sets the MBT12B4 apart 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 physical size. Enhanced grid thickness, higher paste density, and increased active material work together to deliver up to 30% more capacity and power than same-size competitor batteries. This means stronger cold starts, improved voltage stability, and better performance under electrical load.
Built with premium AGM (absorbed glass mat) construction, the MBT12B4 is fully sealed, spill-proof, and extremely resistant to vibration and internal weld fatigue. It’s ideal for harsh riding environments where traditional batteries are prone to early failure. The maintenance-free design eliminates acid handling and routine servicing—just keep it charged during storage.
Shipping factory activated with over 12.5 volts, this battery is ready to install right out of the box. Solid-mounted terminals with threaded inserts provide secure connections and long-term reliability.
If you’re looking for a high-performance 12V AGM powersports battery that delivers more power, greater durability, and hassle-free ownership, the Motobatt MBT12B4 is a confident upgrade built to keep you riding.
