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?
|
|
|
---|---|---|
RedTopFor 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. |
YellowTopUse 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. |
BlueTopThe 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.

Update: This one failed spectacularly after 4 years. One day it was working fine. Next day... nothing. Voltage at 5.5V. Completely dead. I'm on the fence as to whether or not to use Optima anymore. Looking back, the old ones, made in USA, are the ones that really lasted. New ones don't last.
Update to the above update: So it turned out that my Odyssey had a faulty A/C relay, and it was getting stuck intermittently and draining the battery when the car was parked. I used a non-standard charger (my solar charge controller) and was able to bring the battery back from the dead. Also replaced the faulty relay in the car. Considering that all the other Optima batteries that I've used have also lasted 7+ years, I'm changing my rating back to 5 stars.
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.

The Optima in my CJ5 lasted 10 years!
