Odyssey ODX-AGM78 12V 68Ah Extreme Battery, 2 Years Warranty

Modern vehicles with advanced electrical systems and start-stop functionality place exceptional demands on the battery, requiring deep cycle resilience alongside reliable cranking power. The Odyssey ODX-AGM78 is a 12V 68Ah Extreme Battery engineered to meet those demands, delivering 850 CCA (EN) from an Absorbent Glass Mat construction built for high-draw applications.

The ODX-AGM78 is part of the Odyssey AGM2 Thin Plate Pure Lead (TPPL) range. Pure lead plates are manufactured to an extremely fine gauge, allowing a greater number of plates to be packed within the case. The result is a substantially larger active surface area, which translates directly into higher power output, superior charge acceptance, and extended service life compared with conventional lead-acid designs. The TPPL construction also supports start-stop duty cycles – verify compatibility with the product label before fitment.

The battery measures 276mm × 180mm – 186mm (L × W × H) and weighs 22.5 kg. It carries the group reference 78-PC1500. Terminal placement and case type are as indicated on the product label; polarity must be confirmed from the label prior to installation. No IP rating, MCA, Watt-Hour, or NCC classification data applies to this part.

The ODX-AGM78 is one of several Odyssey Extreme variants available on PartsForMachines, including the ODX-AGM34, ODX-AGM34R, ODX-AGM34-78, ODX-AGM65, ODX-AGM24, ODX-AGM27, ODX-AGM31, ODX-AGM31A, ODX-AGM31R, and ODX-AGM31MJ, covering a range of group sizes and terminal configurations.

The ODX-AGM78 is supplied with a 2-year warranty, providing reliable performance assurance under everyday driving and operational conditions.

Standard delivery: 1–3 working days within UK mainland. 30-day returns.
