Optima OPT-D51 YellowTop Dual-Purpose Car Battery 8071-167

The YellowTop® high-performance AGM battery is one of the only true dual-purpose automotive batteries available. With premium cranking power and unparalleled cycling capability (rechargeability), it is perfect for modern accessory-loaded vehicles. The YellowTop can repeatedly bounce back from deep power drains to full energy capacity, so it can power plenty of electronics and still start you up time after time. Lower internal resistance also provides more consistent power output and faster recharges.

Trucks with winches, vehicles with multiple electronics, cars with high-demand audio systems, commercial vehicles and heavy equipment all rely on this battery to provide ultimate starting and deep cycle power.

These batteries contain High Purity lead-tin alloy with “Wound Cell” configuration utilizing proprietary SPIRALCELL® technology.
