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"…
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.
