GS Yuasa has released an AGM auxiliary battery. The Yuasa YBXAX14 has been designed for use in a wide range of popular Audi, BMW and Mercedes 12V auxiliary and back-up applications.
A key feature is the OE-matching lid ventilation for in-vehicle fitment. The end vent hole makes it possible for vehicle OE breather pipe fitting, meaning it can replace the existing back-up battery safely.
The YBXAX14 is supplied charged and ready to fit. It is also maintenance-free with spill proof construction and no free acid, for maximum safety.
