SpiralCell Technology

SpiralCell Technology

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.

What's the difference between OPTIMA RedTop, YellowTop, and BlueTop Batteries?

yellowtop

bluetop

RedTop

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.

YellowTop

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.

BlueTop

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.

Product description

Optima D34/78 YellowTop battery provides the extra performance and deep-cycling capability that your vehicle demands if it has a lot of accessories like running lights, high-performance stereo/AV system, winches, or hydraulics.
