OPTIMA YELLOWTOP Deep-Cycle Batteries
OPTIMA YELLOWTOP Deep-Cycle Battery: Use this when electrical loads are higher than average, or when the discharge cycle is more than typical engine starting, such as vehicles without alternators. This also includes vehicles with significant electrical loads that may exceed the average alternator output (for example, aftermarket audio systems, GPS, chargers, winches, snowplows, inverters, drag cars). This can also include vehicles that have a lot of electronics from the factory, such as a minivan with power sliding doors and a DVD player, especially if the DVD player is used when the engine isn’t running.

Also use for:

• Racing vehicles without a charging system (alternator or generator)
• Dedicated drag-racing vehicles
• Diesel-powered vehicles with aftermarket electronics
• Car audio/video applications exceeding 250 watts over the OE system
• Vehicles or heavy equipment with inverters, hydraulics, winches or other accessories
• Electric vehicles

• Deep-cycle and cranking power
• Up to 3X longer life
• 15 times more vibration-resistant
• Virtually spillproof
• Mountable in virtually any position
• Maintenance-free
• Faster recharging

Why choose OPTIMA batteries?
OPTIMA batteries are the choice among performance enthusiasts who want to add more power to their adventures. Thanks to proprietary SPIRALCELL TECHNOLOGY, these batteries are more than 15 times more vibration-resistant, which means they can take a lot of abuse both on and off the road, and provide up to three times the life of a traditional flooded battery.

OPTIMA battery grids are constructed of 99.99% pure lead. The purity of the lead provides lower internal resistance for additional power and quicker recharging, corrosion resistance for longer life and reduced self-discharge when stored on the shelf.

OPTIMA's tightly coiled Absorbent Glass Mat (AGM) separators hold electrolyte like a sponge to eliminate acid spilling. Each maintenance-free battery is also completely sealed, preventing corrosion and acid spills.
