Maintenance-Free & Factory Sealed

The MF motorcycle battery series is designed to be truly zero-maintenance, so riders can install it and forget it.

  • Factory activated — ready to install and use, no time wasted on filling or charging before first use.

  • Factory sealed — safer operation with no acid leakage.

  • Low discharge rate — holds charge longer when the motorcycle is parked.

  • Maintenance-free design — no water topping up required for the service life of the battery.

Long Service Life & Vibration Resistance

Motorcycles shake, and so does the battery. The UFO-TX and UFO-B series are built with special active materials to survive tough riding conditions.

  • Composite special active materials withstand vibration for a longer service life.

  • Special active materials deliver higher performance per unit of weight.

  • Selected high-quality raw materials for consistent quality from our production line.

  • Stable and reliable performance across the whole range, from 4Ah to 14Ah.

Strong Starting Performance in Cold Weather

Starting a motorcycle in cold weather demands strong cranking current. Every model in this series is rated with a CCA value at -18°C so you can rely on a fast, strong start.

  • Strong starting performance at low temperature, with CCA from 45A to 180A (-18°C).

  • Advanced anti-sulfate technology resists capacity loss during storage and light use.

  • Unique power-boost design supports reliable ignition in demanding conditions.

  • Ideal replacement for common 12V motorcycle battery sizes, backed by UFOPOWER quality control.
