The MotoBatt MBTZ14S is a sealed, maintenance-free AGM (Absorbent Glass Mat) battery from the QuadFlex range. It uses fiberglass mat separators to absorb the electrolyte, delivering superior vibration resistance, stronger starting performance, and a longer lifespan than conventional batteries.
Its standout feature is the patented QuadFlex system — a four-terminal design (two positive, two negative) with threaded brass multi-fit terminals, offering flexible mounting and wider compatibility across various motorcycle models. The battery is factory activated and ready to install straight out of the box, with no acid filling required.
The QuadFlex design delivers up to 30% more power than comparable batteries, and its broad compatibility means only 12 part numbers are needed to cover 80% of the market — significantly reducing the need for large stock holdings.
