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.

ACDelco Gold Automotive AGM Batteries

ACDelco Gold Automotive AGM batteries have high-cycling capabilities, are remarkably charge-receptive, and are necessary for start/stop applications. These batteries are also maintenance-free, 100 percent pressure-tested against leaks, and are manufactured to resist corrosion. Best of all, they are backed by ACDelco's outstanding warranty coverage. When reliable starting power is a priority— ACDelco Gold Automotive AGM batteries are the answer! Additional features include: * Absorbed Glass Mat design is 100 percent leak and spill-proof, because the electrolyte is permanently held in the glass mat separator, instead of free flowing within each cell * Oxygen recombination reduces water loss and reassures maintenance-free performance * ACDelco Gold Automotive AGM batteries have longer life expectancy in traditional vehicle applications, due to a maintained pressure on the plates, which significantly reduces the amount of active mass lost from the grid
