Whether you need a reliable battery for everyday emergencies, today's vehicles are equipped with an abundance of electronics that would have seemed unimaginable just a few years ago. That's where the ODYSSEY Extreme Series Battery ODX-AGM34 78 comes in. These batteries are specifically designed to keep up with the constant technological changes. Unlike most batteries that use a lead alloy, ODYSSEY batteries are made with pure virgin lead, allowing us to fit in more plates. This means more plate surface area and, ultimately, more power - twice the overall power and three times the lifespan of conventional batteries. With up to 400 cycles at 80% depth of discharge, you can rely on ODYSSEY batteries to deliver massive starting power, rapid recovery, and fantastic performance.
