Product Description

Optima D34/78 YellowTop battery provides the extra performance and deep-cycling capability that your vehicle demands if it has a lot of accessories like running lights, high-performance stereo/AV system, winches, or hydraulics. The unique SpiralCell design provides a strong and clean power source, ensuring the safety of you, your family and the environment. The Optima battery is ideal for seasonal use because of its very low self-discharge rate. That means you can store your seasonal vehicles all winter without regular charging and still spring out of the starting block when winter is over.

Really a 4.5 "because"...
By Palm Trees
This is officially my sixth Optima Yellow Top battery, and the first that has had an issue requiring warranty support. Unfortunately, I was told by Optima that Amazon is not on their authorized retailer list therefore I am unable to take it to a local retailer for warranty support. I also confirmed via my Amazon account that it cannot be returned to Amazon. What to do, what to do. Well, even though it is only 9 months old, I bought a brand new Optima from my local Autozone that I know will be an easy exchange should I ever have an issue again.

Now, on to the battery: These have worked well for me in multiple applications from HD trucks to multi-amp-ed Trans Am's and even an off-road Jeep. I've never had one fail until now but be aware that these are not "plug-and-play" batteries like a wet lead-acid type that most people use and/or grew up with when it comes to charging. I'd suggest visiting Optima's web site and reading the differences between their Red, Yellow and Blue top batteries so you understand their application and the type of care and feeding they require. The Yellow covers both cranking amps for starter motors as well as deep-cycle capacity for applications with a large amperage draw such as amplifiers and accessories like winches and such. I've averaged over 6 years out of each battery until I had this one fail and two were going strong when the vehicles left my possession.

I'm guessing that a number of those who are saying this is a bad battery or doesn't last haven't taken the time to learn about them. They can be drained completely down and yet recover where a standard battery won't. But, and it is a big but, they must be recovered following very specific procedures and no, you can't simply hook up a charger and expect it to recover automatically. Do some research and you'll confirm what I already know, these are not standard batteries and yes, they are better than your standard wet-cell batteries, in my opinion. For me, they've outlasted every other type of battery I've used and are what I buy when the stock battery dies or when I need more power for accessories. Peace.

Not worth the hype or the money
By Mark Sanchez
There's a lot of un-due praise for Optima batteries. I believe their reputation is over deserving. Granted batteries don't last long in Phoenix, I was expecting more than the 2 years I got out of my Yellow Top Optima; their capacity and life is not much different than cheaper quality batteries.

Negs:
- The warranty is very poor, nowhere near the level of the competition.
- I expected a quality deep cycle AGM to last a lot longer than just over 2 years.

Pros:
- Worked well under heavy current loads. I run 5 amplifiers that draw about 80-100 amps. The Optima helped buffer the headlight-dimming effect I used to have w/ my stock battery.

Overall a good battery, but at this heavy price I would expect a battery to have a warranty to back it up past 18 months and to last longer than 2 years. If you're spending this much, check out the Diehard Platinum or others first, you'll be glad you did.

4 years, so-so
By G3
First of all, I am a dedicated AGM fanatic, and I won't use leaky wet-cell batteries. That said, I'm not sure if Optima is my brand any more. They just don't seem to last very long. This one was in very intermittent use, kept on a trickle charger, and gave up the ghost after 4 years of really light duty. The failure mode was a lost cell - cranking voltage dropped to 7V. I'm trying out the Lifeline product line in several places - - maybe it will be better than Optima's so-so history with me.
