Review: Use what work and these work! - One is great for your Polaris Slingshot. Three is what I use. Yes, I use three of these. I mounted a Zarate tray in the engine bay and now my Audio and lights are connected to the two batteries up front. I ran on of these for the longest for my audio and it worked well but the Volts dropped pretty fast on the one. I have a 320-amp alternator that helps a lot. now with the three batteries, my Slingshot can run for hours, and I don't get any voltage drops. Before I installed these batteries, people kept telling me to put lithium batteries in my Slingshot. I am sticking to what I know works. These batteries are durable and with multiple connections, the installation of your components gives you options. They do weight 26 pounds each, but the quality of these batteries is second to none. Unless someone can convince me to use a different battery, these are the ones I am sticking to. Review: Optima fit in 2000 Mustang GT with no modification needed - Fit just fine in my 2000 mustang GT battery holder. No modification needed. No clearance issues etc. I should have bought years ago. The one I got is: Optima Batteries 8014-045 D34/78 YellowTop Dual Purpose Battery The battery was about 1mm longer than the tray (from front to rear of car vs left to right), but the tray just stretches out to accommodate. I laughed and said to myself - "Are you serious?!? that's what I was all worried about?!? Lol!" "Good grief - this fit just fine!!! Lol" :-) 1st pic shows Mustang 2nd pic is looking at battery from drivers side - it shows how the tray stretches to accommodate the 1mm increase in size 3rd shows from the drivers side looking at the front of the battery in the mustang - the thing to notice is that the front side didn't need to stretch since it's already stretched on the back side 4th pic shows mustang from the front and how it's installed without the blue adapter, without the large yellow tray adapter, and without the larger of the 2 red adapters (I left them on top to show how they're not used) 5th picture is from the drivers side looking over the battery to show how I used the red clip that came with the Optima. This red clip is the same as the stock black clip. But the new one looks nicer. 6th picture is from the front at headlight level - they show how I didn't run into any clearance issues. 7th shows no clearance issue. The pictures help. See, the Optima site doesn't list it as fitting in the 2000 mustang GT. But yet we all know people put them in their mustangs... So the discrepancy between the 2 kept me from buying for a long time. But all you do is drop it in, and lock it down. In hindsight, it was really no different than any other battery I have ever installed. I used the new clamp that came with the battery vs the factory because because the new one was clean, red, and looked cool, but it was identical in shape to the factory clamp. There were a few other clamp items (blue tray items) for applications in other vehicle types, and they caught me off guard and so I tried to use all of them - partly because I thought they looked cool, but most because I didn't realize that they're actually for different vehicles; it ended up just being the red one, which was the same as the factory black clip that came with the mustang. The other ones would raise the battery with no benefit. I don't remember if there were any clearance issues if it was raised, but don't bother with them unless you're just having fun with the battery changing project and just want to see. You might save them in case you ever get a new car and want to bring the battery - Optima batteries are notorious for lasting a super long time. But yeah - the yellow top Optima fit just fine in 2000 mustang GT. I was all worried that I was going to need to get an F150 tray from a salvage yard (which was a pretty neat idea that someone had done successfully), or order a new cool fancy tray (but those aren't cheap). Neither are necessary, but they're good to know because the knowledge helps guarantee that can somehow fit if your experience is somehow different than mine. But you won't need to do it. You can still do stuff like that it you want, but do it after you put your battery in - because if your tray is the hard plastic one like mine, there is absolutely no problem putting it in. No modification to your tray is needed. I was very happy about how easily it went in. Can't believe I waffled for years over getting one. The low price on desertcart helped too. The absolute best battery I could get otherwise was around 120 dollars, but not nearly the same quality as the Optima. The Optima red top wasn't much more than that on desertcart, but I went yellow because it is an even better battery. Both the red and yellow are great though - WAAAAY better than other batteries. But most people know that about Optima batteries. I don't think they need people to endorse them. I'm writing this not so much because of Optima's quality (already known), but more so 2000 Mustang owners know that they can get this and be happy. It should be the same for any 99-04 mustang, the red or yellow top. But my knowledge is first hand for the 2000, and the Optima Yellow top Optima Battery that I'm rating: Optima Batteries 8014-045 D34/78 Yellow Top Dual Purpose Battery ## Features - BATTERY SPECS: 12-Volt, 750 Cold Cranking Amps, Size: 10" x 6 7/8" x 7 13/16" tall, Weight: 43.5 pounds, Dual SAE & GM Terminals, C20 Capacity: 55 AH - RESERVE CAPACITY of 120 minutes for constant performance.

If any...** A: Amazon has sent me two emails saying that they do not honor the 36 month warranty. Mine failed after less than 2 years. Very disappointing for a $300 battery. **Q: Is this battery good for operating temperature around -15 to 20 Degrees Fahrenheit , and whats the difference between blue , yellow and red tops?** A: Blue is for marine use. Yellow top is called a "deep cycle" battery and is for high demand use such as vehicles with high wattage sound systems or electrical systems that draw a lot of power like off-road lights, snow plows, etc. The red top is for most vehicles on the road and the one I've had the best luck with. The yellow top, if not cycled and/or charged properly runs a higher risk of shorting out, not common, but possible (I did it to one) but I've never had a problem with the red tops. As for the temperature range, it's not going to be much different than a standard batter. Their advantage is they use a a spiral "cell" as opposed to plates that standard batteries use. In theory, their life cycle should be longer as there is less of a chance for the batter to short out as plates are typically close together where in the Optima, the spiral is in a tube/cell of it's own. Hope that helps. **Q: how many amp hours? not cca.** A: As per Optima web site, the battery has 55 Ah **Q: i am looking to use in a race car with no charging system, we manually charge between races, would this be better than red top?** A: My short answer is Yes - the yellow should be better. Deep cycle type batteries do better than regular batteries. They can be run down and then charged back up without consequence, whereas the red is not a deep cycle, so it might not like it as much.Heres my long version. The yellow top has the properties of a deep cycle where it's the better type to use if you have an audio/video system that you sometimes run with the car turned off for a long period of time (and it gets charged back up later when running), so from that perspective, it sounds pretty similar to running it in a race car.But here's where I would be out of my element a bit. It seems to me that it would depend on the type of race and what the power requirements would be. If it was just a drag race where it's starting off charged, and then run for maybe 15 minutes while getting ready for an 11 second run, then I bet either would work well and the determining factor of the winning choice would be weught. And maybe even an entirely different and significantly smaller (lighter) battery altogether might be a better choice. But your question was about yellow or red. I think their weights are pretty similar, so I think you'd get the best performance from the yellow. I believe a deep cycle is made to be more durable and provide sustained power longer (that's the general purpose of a deep cycle from what I remember reading). And they don't have issues being run down and charged back up, so the yellow deep cycle should be better for the guy at a car audio video show, or a race car driver, or i bet even a person that just has a failing alternator, but a short drive to work and a garage and place to park and charge his battery each night.The yellow is a better battery, and I was very pleased with the price I paid for mine too through Amazon. Hope that helps! ## Customer Reviews ### ⭐⭐⭐⭐⭐ Use what work and these work! *by T***K on December 31, 2025* One is great for your Polaris Slingshot. Three is what I use. Yes, I use three of these.

I know I'm old because when my old battery stopped accepting a charge I said "but I just bought this" I did, in Jan 2013 ... 7 years ago. I saw a lot of complaints about warranty and hopefully I won't need it, probably the most important page on the PDF regarding the warranty or lack thereof is pictured here, I'm no lawyer but the battery was new and came in unopened Optima packaging so "limited warranty?" whatever that means. If I do run into a problem later I intend on first doing the math to see if it's been 7 years, next try returning it to where Amazon got it in Laredo,TX. Please note when I first turned over the truck it didn't even engage the starter, just tick tick tick like a dead battery. I cursed a few times then made a couple of pleas and tried again, started just fine I ran it for a while. 2 days later tick tick tick, just like a dead battery after charging it with a special AGM charger it's been working fine ever since, even with the plow attached. ## Frequently Bought Together - OPTIMA Batteries High Performance D34/78 YellowTop Dual Purpose Sealed AGM Car, Truck and SUV Battery, 750 CCA, Dual Terminal, Maintenance Free, Versitile Mounting - Billet Aluminum Battery Pallet - Trunk Battery Hold Down Bracket Perfectly Compatible with Racing Trunk Optima Batteries Tray Blue Yellow Red Top 34M D34M D34 D34/78 34 34/78 - Boao 8-Piece Side Post Battery Terminal Adapter - 3/8 16 Bolts Standard Battery Post Stud Extender Screws --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/4315836-batteries-high-performance-d34-78-yellowtop-sealed-agm-battery](https://www.desertcart.gr/products/4315836-batteries-high-performance-d34-78-yellowtop-sealed-agm-battery) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-09-02*
