This ultimate line of advanced generation batteries is built with maintenance-free design, ultra-premium performance, and all-weather starting protection that discriminating drivers demand for their vehicles. If your car requires an AGM battery, do not substitute a conventional battery. Get superior starting power, high reserve capacity, and long lasting life. Advanced AGM technology with dual purpose design makes it great for quick starts and plenty of competition-quality accessory power for stereo systems boats, RVs, hydraulic lifts, winches, on-board electronics, and many other power demands. The tight-pack plate and separator construction provides added power for resistance against hard-hitting stereo, competitive racing, or off-road wear and tear vibration. Along with a more efficient design, it also has the same case/cover configuration used by original equipment manufacturers for an easier fit into more applications. No elaborate marketing gimmicks or hold-down retrofits—just decades of experience to provide a better fit, more power and longer life.
