Optima dual-purpose batteries are designed to provide both starting and deep cycle capabilities. The Spiralcell Technology offers 15X more vibration resistance and 2X the life of an ordinary wet cell battery. Fully charged, these batteries can sit unused for up to 12 months (at or below room temperature) and still deliver the starting power you need; making them ideal for seasonal applications. A low internal resistance allows for faster recharge, and the spill-proof design prevents external gassing/leaking. Optima batteries are 100% maintenance-free and can be mounted in any position.
