Optima Batteries

If you're looking for pure power, look no further. Optima Batteries to deliver supreme performance and reliability. Optima Batteries over 15 times more vibration resistance and increased cycle life compared to traditional batteries. They’re virtually spill-proof and maintenance-free for absolute peace of mind.

Optima Battery Styles:

RedTop Starting Battery: 

Use this for normal engine starting where an alternator immediately monitors the state of charge and provides energy to the battery whenever it is needed. This would describe most stock vehicles.

Also use for:
- Automotive and RV under-hood starting
- Heavy equipment where starting is the primary function
- Diesel-powered vehicles with no aftermarket electronics

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

BlueTop Marine Battery: 

The BLUETOP starting battery (dark gray case) is to be used when a dedicated starting battery is required; it should never be used for cycling duty. The dual-purpose BLUETOP (light gray case) can be used for both starting and deep cycling; it is a true deep-cycle battery with extremely high cranking power.

Also use for:
- Trolling motors, marine applications with heavy electrical accessories and RVs should use a dual-purpose BLUETOP (which is both a starting and deep-cycle battery)
- Marine applications and RVs when the battery’s only function is engine starting

Note: The difference between BLUETOP and YELLOWTOP deep-cycle batteries is that BLUETOP batteries have both automotive (SAE) posts and threaded studs, while YELLOWTOPS (other than D31T) only have SAE terminals.

If you ever get confused about the colored tops, just remember: If it has a dark gray case, then it’s a starting battery; if it has a light gray case, then it’s a deep-cycle (dual-purpose) battery.
