Optima's Blue Top battery is the ideal marine and motorhome power source. Optima has been a leader in battery technology and advanced battery engineering for more than 40 years. Optima's best-in-class material purity outperforms competing lead alloy models. The absorbed glass mat (AGM) design is perfect for boaters and RV enthusiasts. The Blue Top is a spill-proof battery that's possible to mount in almost any position.

Trust the Blue Top to deliver vital power on accessory-loaded boats. Power sophisticated electronics, trolling motors or other high-drain components with ease. The vibration-resistant design is engineered with active boaters in mind. Boats often sit for weeks at a time. When idle, the Blue Top battery holds its charge, thanks to minimal sulfation.

On RVs, count on the Blue Top to deliver reliable power. It will handle everything from the water pump to the fridge, and from the lights to the stove's ignition. The battery also supplies power to options like TV screens, DVD players, awnings and outdoor steps.

Which Blue Top is Right for You?

The charging system used on your boat or motorhome will determine which Optima Blue Top is right for you.

The Blue Top starting battery

What the Red Top battery does for cars, utes, 4WDs, SUVs, trucks, and vans, the Blue Top starting battery does for boats and motorhomes. It is the right solution when electrical loads are replenished by the factory charging system. Your charging system consists of a generator, an alternator and related components. The Blue Top starting battery delivers many years of high-quality performance.

The Blue Top deep-cycle battery

Boat and RV batteries must deliver prodigious power when heavy loads occur. Electrical demands draw down power faster than the charging system can replenish it. In other situations, a deep-cycle battery delivers power when there is no alternator. The battery is simply recharged later.
