OPTIMA Batteries High Performance D34 YellowTop Dual Purpose Sealed AGM Car, Truck and SUV Battery, 750 CCA, Maintenance Free, Versitile Mounting

Great price on a great product. Performance is excellent as always from optima. Use two of these in a camper Vanagon. They have enough CCA to use as a primary starter, and plenty of AH to use as the "house" battery. Have a similar set in my 2nd Gen Cummins that have lasted quite a while as well

Purchased 3: September of 2020 I've bought two of these for my 2015 Equinox LT (Mothers vehicle) & 2012 Chevy Malibu LS (personal vehicle), and one as a spare. Despite the amount of horrible reviews on this page, I researched it this is basically one of if not the best battery. Now while I don't plan to fully utilize it's capabilities (maybe I'll add running AUXILIARY lights), I wanted it because of its impeccable qualities (Cold cranking, long life, not lead acid, amp draw). I do believe it's worth it for the price, BUT if you need to do alterations on your vehicle consider getting help. (I did it myself and as an Engineer it wasn't to hard just not alot of work room). Totally worth the money. 💯💯👍👍 NOTE: - The manufacturer was correct and that alot of vehicles won't work for this. (both my chevys technically aren't compatible, and my Outback didn't have a battery bracket (so I got a battery reloacter and modified it)) - Reguardless of cold/Heat car will always start - If you forget to turn off the headlights or Interior light, the battery won't be dead the following day. - If your alternator fails on the road (I.E. Battery light), you can drive for several miles with no problem (when I was in this situation, I had driven 30miles in traffic to get home & the car was fine.) - If you aren't sure if this will fit. Autozone carries Optima Now, so ask a clerk there if you can test fit the battery. (Vehicle photos have been provided) Rather: [2012 Chevy Malibu LS] I had to straightened out the termial connectors to make them fit, thank goodness the factory lines have enough slack. (As of February 08, 2023 the Malibu is still running) (I have since sold this car, loved it to peices) Rather: [2015 Chevy Equinox LT] This one was the most challenging, since the factory lines are backwards (meaning when you rotate the battery 180 degrees to have the right orientation ( "↕️↕️ not ↗️↖️" ) the male leads are 4 inchs too far from the female connectors). I had to cut the original heads off the lines and extend them by 6ins so I'd have plenty of slack. That job took me 5hrs to do and it tuned out near flawless. The only issues is that the bracket that secures the battery is now 1.5ins higher then the original postion and when you place everything back together. The hood closes, but there is a slight 3cm gap at the driverside lamp (maybe I'll correct this later, not a big deal). (As of February 23, 2023 Equinox is still running) Rather: [2008 Subaru Outback] Fits nearly perfectly, but if your car doesn't have battery terminal covers. I would suggest getting some, so that the hood/bonnet doesn't ground the terminals out. (As of February 23, 2023 Outback is still running)

Optima Yellow top is the absolute best battery you can put in your vehicle. And I will tell why ... I put them in all my cars. I have had 6 cars carry the yellow top. They have the cranking power to turn over high compression v-8's and just recently installed two into my dad's 2000 Ford F350 Powerstroke 7.3 Diesel. My last yellow top battery lasted 7 years (most batteries last 4-5 years tops), and this battery was used in my 1995 Jeep Wrangler off-road trail rig running a 8000lb winch, 6 off road lights and a stereo with amps and subs. The yellow top is a duel cycle battery. Meaning it is both a starting battery and a deep cycle battery. As a deep cycle battery it will withstand regular discharging and recharging without damage. Where normal batteries will go deceased from multiple discharges/charges. Also these a gel batteries which can be mounted in any position and will not leak. They also withstand vibration better tham common lead-acid batteries which is the most common cause of death to a battery. As a bonus , because they are sealed hydrogen gas will not form over the battery making them safer and corrosion resistant. Stay away from the Red Top , I have tried them 3 times now and they only last about a year before a cell goes dead ... at least that has been my experience. I have heard some people with red top lasting 6+ years, others say the same as myself and had problems. Pro tip - Use Solid Zinc Military battery terminals for solid performance and reliabilty.

I had heard these Optima batteries were very good, so I purchased one in March. I placed the battery in my vehicle and after two weeks it was dead. I charged it up and it died again. I took it out of my Jeep and charged it again and left out of the vehicle. The battery went dead in 9 days. I talked with Optima and they told me to submit a form stating all the facts which I did. I never heard back from them so, I sent another email, again with no response. I then called Amazon and they said they would refund the price of the battery, that was 10 days ago...still no refund. I called Amazon again and I had to talk to a supervisor which I couldn't understand but she said she would refund the purchase. When I received the refund it today it was only for $31.00 of the $309.99 purchase price. This Optima company doesn't honor the refund or warranty policy and apparently Amazon won't back it up either. Buyer beware.

works great, solid build

I tried to install this battery in a 2017 Subaru Outback. The terminals are quite far from the edge on this battery, so the 90° positive terminal does not fit. Also, I received the 34/78 model (seller mistake) and with this model the battery clamp does not fit because of the front terminals. If anyone is interested, I was able to install a group 34 AGM battery from Motomaster. The only modification needed was minor: I had to increase the length of the battery liner by 1".

If you buy an optima battery from amazon and it’s supplied by Canada direct don’t buy it and save yourself a lot of headaches. If your battery stops working and it’s past the 30 return from date of purchase you will not be able to get your battery warranty! Canada direct will not warranty there batteries, optima batteries have a 2 year warranty and when you call optima directly as Canada direct tells you too , optima says they will not warranty because Canada direct is a third party seller on Amazon. Just thought you should know this , I have lived this headache!
