No matter how extreme the conditions, OPTIMA delivers Ultimate Power. We look for every technological advantage to push the limits of what's possible and leave pretenders in our dust.

The OPTIMA YellowTop high-performance AGM battery is one of the only true dual-purpose automotive batteries available. With premium cranking power and unparalleled cycling capability (rechargeability), it is perfect for modern accessory-loaded vehicles. With a 40-year history of technological innovation and engineering OPTIMA products offer unstoppable power for extreme enthusiasts and others who require the ultimate power source.
Trucks with winches, vehicles with high-demand electronics and audio systems, commercial vehicles and heavy equipment can all rely on this battery to provide ultimate starting and deep-cycle power. It also functions well as a forklift battery, tractor battery, or for other applications.
- Deep-cycle and cranking power
- Up to 3x longer life and maintenance-free
- More than 15 times the vibration resistance
- Spillproof, mountable in virtually any position
- Faster recharging and 300+ discharge/recharge cycles
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.

I bought an Optima SC35DA Yellow Top directly from Amazon in August of 2009 and it worked fine until March of 2011. The plastic around the negative battery post just split with gas and gel oozing out.
I did not think there was any problem because this Optima battery comes with a three year full replacement warranty.
Now the warranty merry go round started.
I called Amazon and I was told to call Optima, Optima told me they would not warranty the battery because Amazon is not an authorized reseller, so back to Amazon, then back to Optima and so on.
The final result is that Amazon wound up giving me a full refund of the purchase price of the battery. I would rather of had a new battery but I got tired of the BS and aggravation and then I did what others did, I went to a local discount store and bought a cheap battery.
What is the point of spending $174.00 on what is supposed to be the best battery only to have it fail very early in its life cycle and then have to argue over getting it replaced?
The Optima battery worked for less than two years. So why spend the money on one when you can buy a Wal-Mart special for less than half the price, get it replaced locally or just throw it out and buy a new one.
I do have to thank Amazon for finally giving me the refund but there was too much aggravation involved. From all of the complaints I have read about the lack of a warranty when the Optima Battery is bought from Amazon, you would think Amazon would stop selling it.
This is exactly why I gave it only one star.
I can only recommend that no one should by any Optima Battery Product from Amazon unless they are fully aware that there is no warranty at all.
I started out looking at the Optima Red Top, but the reviews were not as as good & people I know have had problems with their Red Top battery failing. Now the choice was between the Sears DieHard Platinum & the Optima Yellow Top.
The Sears DieHard Platinum looks like a very good battery & it's said to be made by Odyssey. Not really sure that's true? What pushed me over to the Optima Yellow Top was the heaver weight, much higher cost & shipping hassles if I went with the Sears DieHard Platium.
The Optima Yellow Top was delivered quickly by UPS. It comes in a heavy-duty, double walled cardboard box. The battery inside the box was protected with more cardboard packing & the top of the battery was covered with a protective plastic cover. With the attached removable lift handle, the battery was easy to remove from the shipping box. The battery was in perfect condition!
We found the Optima Yellow Top sits lower than a standard type 35 battery. Not a problem, since a spacer is provided, which snaps onto the bottom of the battery. This made the battery fit perfectly in my son's '03 Subaru Forester. The battery comes fully charged, so once we hooked up the cables, the engine started right up!
We would recommend this battery & the plan is to install one of these in our other 2 vehicles.

Since I wrote this review, I bought another Optima Yellow top for our '95 Neon Sport. I should note that this isn't a direct replacement for the stock battery in the stock location!Read more ›
In my case I leave accessories on 24x7 like my escort radar detector. It's to ensure that the gps data is up to date and to keep the microwave components warm so when I leave in the early morning they are on frequency and yield accurate measurements.
The yellow top is a cross between the deep cycle marine blue top and the starting red top. It has plenty of CCA's to turn over the engine the next day, plus it is not damaged by being drained. I do keep my yellow top "topped off" with a ctek charger CTEK Multi US 7002 12V Battery Charger whenever possible, but the battery holds its own even without ac charging.
Yes, Optima cells are expensive, and that is their one and only downside. Mine came with adapters to make it fit my vehicle like a factory cell. I get more years out of an optima vs. an interstate by quite a bit, so there is a value proposition as well. Just not being stranded from headlights left on is a great feature!
