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 34R 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.

    Replacing after 7 years, ordered 34R-003 but in box was 34-002
    4 Stars
    Replacing after 7 years, ordered 34R-003 but in box was 34-002
    Previously running Optima Yellow Top 34 since 2016, still works and still starts but starting to go weak over the last year so trying the Red Top after 7 years for more CCA and hopefully same level of longevity. Strangely, after installing the battery I remembered ordering the 34R which is model -003, and the box label shows 34R -003, but I didn't remember seeing "34R" on the battery during installation. Sure enough, the battery in the box is a 34 -002 battery, and I don't know what the difference is between these batteries.I checked the battery voltage upon unpacking, and it read 12.4V. I charged the battery over a few hours to full, and it read 13.1V when installed. First start was very powerful with no power sag as the old battery was typically exhibiting when idling. The car sits for days or a week without starting so during these early periods upon installation I'm keeping it charged when not running to maintain battery health, and after a week the battery reads either 13.2V or 13.3V after charging and will drop down to 12.6 or 12.4 after sitting for a couple days slowly discharging, a good sign it's a healthy battery.7 years ago the Yellow Top was $130 less in price and lasted that long without the attention I'm giving this Red Top right out of the box, the old one is disconnected and fully charged with some life left in it. Although Amazon says this does not fit my vehicle it is a perfect fit. Maybe I got lucky getting a 34 instead of the 34R because I don't even know why I'd need one over the other, they look exactly the same.
