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.

works great, solid build

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.

Overall, this battery has been reliable and it seems I got a decent one, even though I've killed this battery multiple times over the years by draining it by accident, letting it sit too long without starting and maintaining, or other ordinary situations. I probably need to replace it by now, but as long as I keep an eye on the battery being charged between starts, it continues to function. I didn't know 5 years ago that there was any issue with these batteries being made in Mexico and of lesser quality control, but mine is one of those and has been working great compared to conventional lead acid batteries. 5 years ago I paid almost 100 dollars less than the current price, so I'm not so sure I'd buy another one at these prices, and I'd explore other reliable AGM options first. However, I got a very well performing D34 yellow top to start a 40 year old Jeep that was never a daily driver, and although Amazon says it won't fit my vehicle, it fits an AMC FSJ perfectly. Whenever I had the chance to keep the battery on a maintainer/charger for a week or two between starts, I did. Over 5 years that 15 or so year old charger didn't seem as effective so I recently got a new smart charger that has an AGM Mode to see how much more life this Optima battery still has in it. I have my doubts that it's holding its original charge that it had when it was new, so I'll have to check it but as long as it isn't drained it still starts the 360 V8 in cold winter below 30 degrees. The old truck definitely seems to slowly discharge the battery when it sits, so maintenance is a must. I've brought this battery back from an almost completely dead state a few times using a slow recharge, so I've been satisfied with the resilience of the battery design and the extra deep cycle cranking amps. An ordinary battery would have been wrecked and maybe would need some expert regeneration techniques just to perform like this one has without having to take it out of the engine bay. If I could get another one that works like this one did for the same price it was 5 years ago, I would.

I put this battery in my 1990 Jeep Wrangler, which is a weekend toy that I hardly use. I often go months without starting it. It takes a good bit of cranking to get the gas up to the carburetor and this battery has no problem cranking for minutes after lying dormant for a long time.

Okay, tell me how this relatively small size battery puts out as much power as a considerably larger battery of the same specs? Replaced the battery in my 2005 Ford Crown Vic CVPI P71 with this battery (Because it had a yellow top and matched my yellow Accel coils. Can you think of a better reason?). It is considerably smaller than the one I took out that took up almost the entire battery tray. This takes up about 4/5s of the tray, and it's also narrower and comes with little clip on attachments to make it able to be clamped down into the existing tray. Because the battery has the little round towers it comes with a special plastic hold-down to replace the stock hold-down bar. It JUST fits with some wiggling around. Because the Optima hold-down is curved and MUST fit around the round tower, and makes the battery sit against the tray edge towards the radiator, it CANNOT be centered in the tray. Because the battery is smaller and the provided clamps position it towards the front of the car AND the posts are pretty far from the battery edge, the battery cables JUST reached the posts. The attaching end I have on the positive cable is a one piece deal that is part of the cable assembly and did hit on the battery edge and had to be bent to fit. The negative cable could ONLY be positioned diagonally because it was not long enough to reach the terminal at a 90 degree position on the terminal. So, I would NOT consider this a direct replacement battery for my vehicle. BUT, it is yellow and matches the coils, so it looks cool, and that's what is most important, right? The battery seems to be working okay, so I'm keeping my fingers crossed that it lasts a while since it's plenty more than running down the street to my car guy and having them pop an Interstate Battery in the thing that they will prorate if it goes bad.
