Going Farther for Longer
Installing an OPTIMA BlueTop high-performance AGM battery in your boat or RV means exceptional running time and more recharges than you’d get out of a traditional battery. It’s the perfect marine battery for boats with trolling motors, extensive electronic systems, and works well as an RV battery for RVs with creature comforts that tend to drain batteries quickly. On top of providing outstanding vibration resistance, the BlueTop efficient power delivery and faster recharge time mean you’ll spend less time worrying about your battery. This means more time for fun. Again and again. This flexible boat battery and RV battery is ideal for those who need a sure-starting, strong-cranking, maintenance-free power source.
- Up to three times more recharges than other marine batteries
- More than 15 times the vibration resistance
- Spillproof, mountable in virtually any position
- Works well as a boat battery or RV battery
At the heart of every OPTIMA battery is a series of individual spiral-wound cells comprised of two pure (99.99%) lead plates coated in a precise coating of lead oxide. One coated plate is positive and the other is negative.
The unique manufacturing process of spiral winding continuous lead plates is far more precision-controlled and expensive than building traditional flat plate AGM batteries. Custom automated cell-winding machines are required to maintain the close tolerances required to maintain quality and performance. Critical tolerances, temperatures, humidity and automated processes are maintained and constantly monitored.
OPTIMA has built over 100 million individual spiral cells since the early 1990’s. No one knows how to build the highest quality and best performing spiral-wound batteries better than OPTIMA.
What's the difference between OPTIMA RedTop, YellowTop, and BlueTop Batteries?
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, including: automotive and RV underhood starting, heavy equipment where starting is the primary function, and diesel vehicles without aftermarket electronics.
Use this when electrical loads are higher than average, or when the discharge cycle is more than typical engine starting, such as vehicles with multiple electronic accessories and vehicles without alternators. This can also include vehicles with a lot of factory electronics such as power sliding doors and a DVD player. Examples also include: racing vehicles without a charging system, dedicated drag racers, diesel powered vehicles with aftermarket electronics, and vehicles with inverters, winches, or other accessories.
The BlueTop starting battery (dark gray case) is to be used when a dedicated starting battery is required and it should never be used for cycling duty. Use a BlueTop starting battery for marine applications and RVs when the battery's only function is engine starting.
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. Uses include: trolling motors, marine applications with heavy electrical accessories, and RVs.

Without a dought, this is the worst battery support I have ever had to deal with, and it's the worst battery that I have ever purchased. I have been buying batteries for more than 40 years. I never had this problem with other brands. I even purchased their expensive charger, which did not help one bit.
Do yourself a favor and buy something else somewhere else. There is no support for this product on Amazon and the product died in only 1 1/2 years.
I run these batteries with a 24v trolling motor on 24' center console by boat. I can run 3-4 days without a charge in calm conditions and a 8-10 hours in windy conditions (20-30 mph). I noticed about 40% difference in run time compared to regular type 31 batteries.
