Odyssey Battery

<h3>About ODYSSEY Battery</h3><p>Few names in the battery industry carry the weight of <strong>ODYSSEY Battery</strong>. Born from decades of engineering innovation, the ODYSSEY brand traces its roots to 1995, when Hawker/InvenSys expanded its Warrensburg, Missouri facility to pioneer flat-plate battery technology. The following year, the ODYSSEY battery was introduced to the marketplace — and the industry hasn't been the same since. In 2002, EnerSys acquired the brand, and today ODYSSEY operates as a flagship line under EnerSys, the global leader in stored energy solutions for industrial applications.</p><h3>The Technology Behind the Performance</h3><p>What sets ODYSSEY apart is its proprietary <strong>Thin Plate Pure Lead (TPPL)</strong> Absorbed Glass Mat (AGM) technology. Because the plates are made from 99% pure lead — rather than the lead alloy used in conventional batteries — they can be made extremely thin, allowing more plates to fit inside the battery case. More plates mean greater surface area, which translates directly into more power. The result: engine cranking pulses up to 2,700 amps for five seconds, roughly double that of equally sized conventional lead acid batteries. Couple that with an 8–12-year design life and a 3–10-year service life, and you have a battery built for the long haul.</p><p>The sealed AGM construction also means ODYSSEY batteries are completely maintenance-free — no watering, no acid spills, and no worries about orientation. They're engineered to tolerate extreme temperatures from -40°F to 140°F and are rated for up to 400 charge-discharge cycles at 80% depth of discharge, making them a true dual-purpose solution for both starting and deep-cycle demands.</p><h3>A Battery for Every Application</h3><p>ODYSSEY's lineup spans a remarkably wide range of applications. Their <a href="/498-odyssey-battery-vehicle-battery-2476">vehicle batteries</a> cover everyday cars, trucks, performance vehicles, and commercial fleets — available in multiple BCI group sizes and even found as original equipment in a number of commercial trucks and performance vehicles. For those on the water, ODYSSEY's <a href="/498-odyssey-battery-batteries-200137">marine batteries</a> bring the same dual-purpose starting and deep-cycle capability that fishing enthusiasts and serious boaters depend on. Out on the trails or on the snow, <a href="/498-odyssey-battery-batteries-201357">powersports batteries</a> are engineered to withstand the constant shock and vibration that would quickly destroy lesser batteries. Heavy-duty and RV operators aren't left out either — ODYSSEY's <a href="/498-odyssey-battery-batteries-201672">heavy-duty batteries</a> are purpose-built to power the growing array of onboard electronics in commercial trucks, buses, earth movers, and recreational vehicles.</p><p>Beyond the batteries themselves, ODYSSEY also offers a complete ecosystem of accessories. Their <a href="/498-odyssey-battery-battery-hold-down-1336">battery hold-down kits</a> provide secure, vibration-resistant mounting solutions designed specifically to complement ODYSSEY batteries in demanding installations. The brand has also expanded into battery chargers and monitoring systems — including the ODYSSEY Connect system, which uses patented microchip technology to track state of charge, state of health, voltage, and temperature via a Bluetooth-connected smartphone app.</p><h3>Trusted by Professionals and Enthusiasts Alike</h3><p>From weekend off-road adventurers to commercial fleet managers and racing teams, ODYSSEY Battery has earned a reputation for delivering <strong>extreme power, exceptional longevity, and unmatched reliability</strong>. With manufacturing facilities across the United States, the United Kingdom, and France, and a warranty backed by one of the world's largest stored-energy companies, ODYSSEY continues to set the benchmark for premium AGM battery performance.</p>
