Optima YellowTop Deep-Cycle 12-Volt Batteries
Optima YellowTop Deep-Cycle 12-volt batteries are high-performance, dual-purpose power sources. They're great for applications requiring repetitive amperage drain and quick recharging—like trucks with winches, commercial or public safety fleets, and vehicles loaded with electronics and accessories. YellowTops also power forklifts, tractors, and other heavy equipment. The maintenance-free AGM batteries deliver premium ignition starts, while sustaining high power levels even when system loads exceed the alternator output. Optima deep-cycle models are sealed, spill-proof, and can be mounted in most any position. They are far more resistant to vibrations than standard batteries, and will perform up to three times longer. For consistent power and faster recharges, order the YellowTop designed for your needs.
