The MTX battery line for cars and trucks offers long life and premium performance as an absorbed glass-mat (AGM) battery or enhanced flooded battery (EFB) battery and a 36-month free replacement warranty. Get the right OE replacement battery for your start-stop vehicle, whether it came from the factory with an EFB battery or an AGM.

•  MTX AGM batteries: The MTX AGM from Interstate Batteries is an absorbed glass-mat battery using a revolutionary design that, instead of letting free-flowing liquid in a battery cell, suspends electrolyte in fiberglass mats. This design packs more lead into the car battery, giving you the longest life possible, while the battery itself is spill-proof and vibration resistant.
•  MTX EFB batteries: The MTX EFB from Interstate Batteries is designed like regular flooded batteries with critical differences that allow an EFB battery to outlast a regular battery between recharges. The Interstate EFB battery is only suitable as an OE replacement for vehicles requiring an EFB battery.
