Our Promise

Ultimate Power, for the ultimate professionals, for the ultimate enthusiasts. And for the ultimate experience. That's our goal each and every day. We look for every technological advantage to push the limits of what's possible and leave pretenders in our dust.

We manufacture our own batteries in our own facilities to our demanding standards.To ensure quality and consistency in our batteries, no matter where they are being sold - our batteries are never re-labled or re-spec'd.

Gentlemen, Start Your Engines

The RedTop high-performance AGM battery is the ultimate starting battery designed to deliver a powerful burst of ignition power for a reliable start-up every time. It will withstand hard launches, extreme corners and is race proven for every road every day whether it's used as a truck battery, automotive battery, or for other applications. Its reputation as a truck battery or automotive battery is unsurpassed.

  • Strong starting burst
  • More than 15 times the vibration resistance
  • Spillproof, mountable in virtually any position
  • Maintenance-free with up to 2x longer life
  • Faster recharging
  • With impressive high-power delivery and extreme resistance to the most common causes of battery failure, the RedTop is ideal for trucks, SUVs, hot rods, street cars.

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?

redtop

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 25 RedTop is designed to deliver high power cranking ability even in harsh weather conditions. This battery is great for heavy use by hot rods and off-roaders with its leak-proof, high power, and starting ability. The unique SpiralCell design provides a strong and clean power source, ensuring the safety of you, your family and the environment. The higher reserve capacity gives you a longer shelf-life to give you the power when you need it, where you need it.

    The battery died on my Scion tC and I went straight to Amazon to find a new one. I have had an optima Red-Top in my Prelude for about 6 years now and it still runs strong (Worth it for just the winter starts alone), so I naturally went for the same battery this time. As far as the battery is concerned:......Works great right out of the box......Battery was charged enough from the factory to get the car started right out of the box.......Size and weight are very close to the OEM tC battery, It fit right in place with no mods. (Also, I do agree with the previous poster who said the terminal protector case would serve great as a booster to pick the battery up an inch or two. It's just a square piece of plastic)As far as the shipping and packing by Amazon is concerned:......First, I'll admit, I was concerned about the shipping based on what I read in the other reviews, but I know Amazon is on top of most problems pretty quickly and I was hoping they had addressed the packing issue by now. So I went ahead and ordered.......Well, as soon as I opened it up, It was obvious they fixed the packing problem. It was packed VERY well. You can see in the pictures that the used chunks of cardboard pieces sandwiched between an inner and outer layer on all four sides. No cheap popcorn or anything.......The battery arrived with no dents or scratches......Never doubt Amazon, my son.All and all....a great buy!
