Optima D35 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. The unique SpiralCell design provides a strong and clean power source, ensuring the safety of you, your family and the environment. The Optima battery is ideal for seasonal use because of its very low self-discharge rate. That means you can store your seasonal vehicles all winter without regular charging and still spring out of the starting block when winter is over.

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.

Pro Tip -
Mounting : This battery is NOT a direct fit to the battery box. Optima doesn't make a direct fit replacement battery for a Porsche 996 at the time of this post. A custom spacer is needed to lock down the battery so it doesn't move. Some people use a high density plastic, like a thick cutting board to fashion one. I used a 12mm or 13mm combo wrench as a spacer. It was the perfect size, shape and had the rigidity to do the job. I was able to really crank it down and the wrench had enough tension to act like a strong spring on the hold down tabs of the battery. This might sound like a "backyard fix". It works, and works great. I have had the battery in the Porsche for a year and 6,000 mi now. It has withstanded a lot of spirited driving , jars and bumps and still it's solid.
Battery terminals are in the correct orientation and the Factory Porsche Battery cables are plenty long enough to reach.
Weighed in at 37.7 lbs vs 41 lbs for the stock battery, so shaved off a little over 3lbs of dead weight. This was a nice incentive as it reduces high center of gravity front-end weight a little bit. Even though lighter, my yellowtop has 70 CCA more than the stock battery and a lot more reserve capacity.
Cranked just fine, very strong, and hopefully will have a long life ahead. Even if not so, the 3 year free replacement warranty (not some pro-rated scheme) direct from Amazon gives me a lot of confidence.
Also, I chose the Yellow over the Red since Honda's have a so-called "intelligent" charging system that seldom applies 14.4v current to the battery. Instead, the system is purposely setup to drain down the battery a good amount so the alternator has no load and this can help fuel economy/emissions. Net effect is increased drain-down wear and tear to which the Yellow top should much better resist than the Red, or any other non deep cycle battery. Although some may fault the lack of CCAs over the Red, I once again remind you that this has 70CCA more power than stock.
The battery is brand new (as advertised) and included the Optima brand optional spacer (if your OEM battery is taller than the Optima just clip the optional spacer to the bottom and it is the exact same height as the taller OEM battery).
I am glad the spacer was included because my car required a taller battery. I hooked up the battery to the car and it works as expected. So far I am 100% satisfied.
I expect the battery to work well for a long time since I bought an Optima yellow top battery for another car years ago and have never had a problem with it.
Bottom line, the battery is brand new, and arrived quickly and in perfect condition for a great price.
