Odyssey ODX-AGM31M 12V 100Ah Extreme Battery, 2 Years Warranty

Large-format commercial and marine applications demand batteries that combine exceptional cranking performance with deep-cycle resilience – a combination conventional lead-acid designs struggle to deliver consistently. The Odyssey ODX-AGM31M is a 12V 100Ah Extreme Battery built to meet precisely those dual demands, rated at 1150 CCA (EN) and classified NCC Class A for the highest reserve capacity tier.

The ODX-AGM31M is built on Odyssey's AGM2 Thin Plate Pure Lead (TPPL) technology. Pure lead plates are manufactured to be extremely thin, allowing significantly more plates to be packed into the case. More plates equate to greater surface area, greater power output, and improved charge acceptance – all without the performance degradation associated with conventional lead-alloy construction. The sealed AGM design is maintenance-free and spill-proof." The battery measures 330mm × 173mm – 239mm (L × W × H) and weighs 34kg. It carries the cross-reference code 31M-PC2150. Terminal placement and polarity should be verified against the product label prior to installation. This product supports start-stop technology – confirm compatibility via the product label. Case type: consult product label. "The ODX-AGM31M is one of several sizes within the Odyssey Extreme AGM2 range, including ODX-AGM34, ODX-AGM34R, ODX-AGM34-78, ODX-AGM78, ODX-AGM65, ODX-AGM24, ODX-AGM27, ODX-AGM31, ODX-AGM31A, and ODX-AGM31R, allowing selection by group size and terminal configuration.

This battery is supplied with a 2-year warranty, providing documented assurance of service life and manufacturing quality.
