The MTX line offers extended service life and premium performance as an absorbed fiberglass (AGM) battery or enhanced flood battery (EFB) and a free 36-month replacement warranty.
Interstate Batteries' MTX AGM is an absorbed fiberglass mesh battery that uses a revolutionary design that, instead of allowing the liquid to flow freely in a battery cell, suspends the electrolyte in fiberglass meshes. This design contains more lead in the car battery, giving it the longest possible life, while the battery itself is spill-proof and vibration resistant.
On the other hand, Interstate Batteries' MTX EFB is designed like normal flooded batteries with critical differences that allow an EFB battery to last longer than a normal battery between recharges. The Interstate EFB battery is only suitable as an OE replacement for vehicles that require an EFB battery.
