Exide GNB Marathon High Temp FTX valve-regulated lead acid batteries have been optimized for high temperature operation. Engineered for premium performance and maximum battery life, Marathon FTX batteries have a 15 year battery life design. These batteries feature a high-compression design utilizing Absorbent Glass Mat (AGM) technology for greater than 99% recombination efficiency and superior Lead-Tin-Calcium-Silver Positive Alloy to resist corrosion at higher temperatures. MICROCAT® Catalyst (one per cell) reduces float current and minimizes water loss, combating processes which can prematurely age VRLA batteries. A patented diamond side-wall design paired with durable flame retardant polypropylene container and cover help minimize water loss and maintain structural integrity in higher temperature operating conditions. Exide GNB Marathon High Temp FTX Batteries are perfect for telecom, cable / broadband, utility, emergency lighting, & security applications. The Exide GNB Marathon FTX is available in the M12V155FTX & M12V180FTX models.
