5.0 out of 5 stars One tough battery
Reviewed in the United States on June 11, 2024
I use this battery to power a forestry winch. It easily pulls down a half-dozen large oaks on a single charge and recharges all summer long with no problems. I only replaced the last one when a tree fell on it and cracked the case open. Even then, it continued to work fine and nothing appeared to leak out. They're pricey for sure, but when you've gotta have a good battery, they can't be beat.

5.0 out of 5 stars So far so good
Reviewed in the United States on February 25, 2011
I have a 2008 Dodge Grand Caravan that has been modified for wheelchair use. Pushing the passenger sliding door button on the remote opens the door, slides a ramp out, and lowers the right rear quarter of the van so the ramp angle will be less steep. When it got frigid this winter, I would open the door, get in the van, close it up while I transferred out of the chair into the driver's seat, try to start the van and - you guessed it - not enough power left in the battery to turn the engine over. After the third time, I decided that I needed a new battery.

I did some research and decided that an Optima Yellow Top Dual Purpose battery was just what I needed. Arrived *very* well packaged from Amazon, and even without charging it up, it ran through all of the non-starting actions and proceeded to start the engine in 10° weather.

So far, I haven't had any problems whatsoever. The only negative is that there is only a 36 month warranty for a battery that is as expensive as the Yellow Top.

Update:
Two years in, and absolutely no problems with the battery.

I installed the yellow top in my 2003 1500 HD truck. This battery lasted me 8 years. Didn’t fail on me but I don’t want to take a chance. 8 years is plenty. Just bought a new one. Great battery. You get what you pay for!!

1.0 out of 5 stars Hard to get warranty service for defective items
Reviewed in the United States on June 4, 2023
I got this item and it was defective. I tried to get warranty service from Amazon but they refused and told me to go to the manufacturer which I did but was bounced back to Amazon and they still refused to service the warranty. I’ve reminded Amazon of their policy that clearly states on their website “If you’ve purchased a defective automotive item , shipped from and sold by Amazon.com, that is covered by a published manufacturer warranty, Amazon honors the warranty. Amazon will either replace the item or refund the cost of the item for the life of the published warranty” but they still refused. so back to the manufacturer I went. They required me to go to a shop to get the battery tested and get a load test report. While doing so the battery started smoking and filled the place with smoke. The machine doing the tests automatically shut off and wouldn’t give a report. I told optima this and they said I needed a written statement from the test facility and they refused to do this because they were not the ones that sold it to me Amazon did and giving a written statement would make them liable. So here we are. Stuck in limbo and I still don’t have a resolution for a $300 supposed top of the line product. It’s frustrating to say the least.

5.0 out of 5 stars Optima fit in 2000 Mustang GT with no modification needed
Reviewed in the United States on October 22, 2016
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 Amazon 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 Amazon, 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

5.0 out of 5 stars Really outlasts other batteries
Reviewed in the United States on November 13, 2023
Like everything else, batteries seem to have become outrageously expensive. But when it was time to replace my boat batteries, I chose the same ones. The other OPTIMA lasted a long time (one 10 years, the other 7 years). Just about any other conventional marine battery I had before lasted 2-3 years, tops. Also, the type of engine I have with hydro-electric steering requires a certain type of battery. So this is a very high performance battery, although I wish it would be less expensive - but I suppose you get what you pay for. Would always buy again, and now am thinking of getting them for my RV as well. More money, but lasts much longer.
