Outstanding pick for a weekend warrior car that sits during the week
Style: Battery
Product Packaging: Standard Packaging
I've consistently used Optima Yellow Top D35 on my weekend fun car (heavily modified 2002 WRX) that sits during the week and sometimes the battery drains down. It start very strong every time. Most recently I left the car for about 3 weeks just after installing the new battery and without much driving on it, and came back expecting the battery to need a jump, but I turned the ignition and it fired right up. The extra cost is a million times justified in my mind considering my experience with cheap batteries that last about a year or two. I've had Optima Yellows last 8+ years easy and have not seen deterioration in quality in the maybe 15 years I've ran them on my two cars. My "battery for life"

I bought this battery September 2016. Been running it in a 14 XV Crosstrek with pretty powerful multi amp sound system. Battery just died today. FEB. 22 2026. Pretty amazing battery but price has gone up so much I might have to try a cheaper alternative.

Was good, poor and slow support.
Style: Battery
Product Packaging: Standard Packaging
I was a fan of Optima. My first two batteries lasted over 5 years here in hot Florida. My 3rd barely lasted 2 and a half years. Yes it only had a 2 year warranty, but after reaching out to their support I was severely disappointed. They did not comprehend the answers I gave that they asked me, and refused a replacement or a discount on a replacement. I'm sad a brand I used to swear by stopped communicating with me. I think they made great batteries, but their support is slow, sloppy, and inconsiderate.

2001 Porsche Carrera 911 (996) battery
Style: Battery
Product Packaging: Standard Packaging
Confirmed fit in 2001 Porsche 911 (996) 3.4L Coupe. This battery is the best battery you will get for your Porsche. Typically I get about 7 years out of the yellow top and most of us don't daily our 911s so a deep cycle battery like this one won't let you down. Deep cycle batteries are tough and Optima gel cell batteries resist vibration, which is the primary killer of a battery. My 996 tends to sip down electricity just sitting. Repeated draining of the battery will kill a standard battery , even a red top Optima... which are trash (IMO) but the yellow won't suffer nearly as bad as a standard battery. Car cranks nice and strong every time even if she sits for a week or two. 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.

A wise Birthday gift request!
Style: Battery
Product Packaging: Standard Packaging
After doing a lot of research on AGM batteries, I finally decided on this one. This was a Birthday gift for my son, to be installed in his '03 Subaru Forester. 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. ► Update - October 23, 2012 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! We relocated the battery to the trunk & a sealed battery (less chance of gassing) was the way to go. We completed this project over the summer & it was a complete success! As to the previous battery installed in the my son's '03 Subaru Forester. It's been 100% trouble free! :) ► Update - July 13, 2016 We have 3 of these now & 100% trouble free! :)

bad battery warranty....
Style: Battery
Product Packaging: Standard Packaging
I purchased a yellow top battery through amazon 12-22 and it is not holding a charge anymore. It only shows 11.2 volts. I have been buying Optima batteries for over 30 years for my vehicles. I own at least 3-5 vehicles at any given time. I started when I was young due to stereo systems but continued the trend because I felt they were a superior product. The last two I have gotten have failed at 3.5 years and this one has started failing at less than 2 years and now will not hold 12 volts. I sent an inquiry and got no response. Can someone help me with this? After words this is what ended up happening :through email they were not helpful but when amazon provided a number the process for warranty was fast and easy. They shipped out a new battery within a week. It was nice to see they have a person on the other end helping you through the process . Nice touch.

Optima yellow top 218D35
Style: Battery
Product Packaging: Standard Packaging
This is my fourth purchase of an Optima dry cell battery. I still have all four. My old Chevy 4x4 pick up. I bounced down the road cause I drove the heck out of it. Battery acid was everywhere and I was replacing the wet cell batteries every year. In 2006,I installed an Optima Red Top. No more spills and better starting power. I have used that same old Red Top in two pick ups and one car, sold the cars but kept the battery for a spare cause it fits most applications and still starts most any car or pick up at 6 years old. In 2006 our new pick up kept going dead cause we parked it most if the time. The alarm system would kill the wet cell battery after a couple of weeks parked. Bought a Yellow top, now it can be parked for just over a month with the alarm on before the batter goes low. We stored the pick up for three months with the alarm off and it never went dead. Yea you car alarm will kill your battery eventually. Yea you'll need a deep cycle type maintenance free setting on your home battery charger, if you need to recharge Optima batteries. Most new chargers have that setting too. If you buy a new charger with the 50 amp jump starting feature, you'll never wait for a tow truck. My old 2008 corolla needed a replacement battery in 2012. Yep, Optima Yellow Top was my choice cause I like to listen to the stereo with the engine off for hours. The car always starts right up now. Oh yea put two Optima Blue Tops in my boat for peace of mind. Wired in a Perko boat battery switch so I never have a dead battery. If we beach the boat and play the stereo all day long, I can switch to the full battery to insure we all get home safely. Yea you can do the same with wet cell batteries but they won't last as long and charge back up as easy as Optima batteries. Plus you can mount Optimas sideways or upside down to make more room. Just don't short out the battery terminals. Note:some modification of battery mount hardware may be needed in some applications but most just fit perfect. Check the battery post locations before you buy. I looked at the over priced batteries at my local car parts store first, took some measurements, then ordered from Amazon. Yes Optima batteries are about double the price of most replacement wet cell batteries, but well worth it. Amazon is awesome, the lowest price and you don't have to carry the new battery home. Who doesn't love free shipping. Order yours today and in about a week the nice Fed Ex or UPS person will carry that heavy battery right to your door or garage.
