    • Super fast delivery and with good build quality
Product Packaging: Frustration-Free Packaging
Super fast delivery and with good build quality. Come with 77% of battery left and now is charging. Preparing to install it to my RV. after one and half years use (connecting with a 5w solar panel and a solar charger controller), the battery dead. the battery is still able to be charged by a Black Deckor 15A battery charger but not able to hold the charge (still have cranking capability after tested with an electric battery tester). after contacting with optima, they are not able to honor the warranty (the technical said the one of the cell of the batter might dead) but i have to consult with the original re-seller which is Amazon. After calling Amazon, they can send me a replacement or a full refund. i choices a refund then to get another one from costco coz I do not want to wait. the price i purchased in the past is about 80 dollars cheaper then current price. so, i think that i got a very good deal in the past. basically, i like Optima and I like Amazon! The one fails may just because the discharging speed of the battery itself is bigger then the charging rate i provided from a tiny 5w solar panel.. i bought a 40w bendable solar panel instead. hope this time works! ... show more

    • Pricey but not when compared to the cost of not having it is
Product Packaging: Frustration-Free Packaging
Early c5 Corvettes have a design flaw. They put the battery directly above two computer components. Over time conventional batteries have been shown to leak and destroy wiring to these components resulting in costly repairs. My research showed that this was by far the AGM battery recommended to overcome the problem. Installation was easy and a variety of mounting options were included. Hoping for the best over the long haul. ... show more

    • This BS is a total scam
Product Packaging: Frustration-Free Packaging
This thing is a total dog compared to walmart batteries for 1/3 the price. The reserve capacity is terrible, the CCA is only 800 - yet I wanted something to last. With that said - I am not happy. I thought "hey buy the best of the best and you'll finally be happy." This is not the case. An $80 walmart battery outperforms this battery in nearly every aspect. I am within my return period and I am literally seconds away from returning it. I could buy 3 walmart batteries and put them in parallel/series and see some serious business for the same price. I have some parasitic drain and my 2 year old no-name battery usually takes a week or two to run flat. This thing dies overnight. Additionally, the cheap no name battery does 950cca easily - where this POS only does 800. This company at this point is literally scamming people on name alone. There are BETTER batteries for MUCH LESS. My only saving grace IF I KEEP THIS BATTERY is that it will last for way longer. But with the results I've gotten in the past couple days I would not trust that or invest this way. I could buy a new BETTER battery every couple years and have a better outcome. This thing would have to last over a decade to be worth it. But with my current results I am not convinced the reduced performance and lackluster results are boding well for this battery. Frankly, I will most likely return this thing within the week. Be a smart person!!! If you're looking for output - there are better batteries for WAY LESS. If you're looking for capacity there are better batteries FOR WAY LESS. If you're looking for longevity - for the same price you could just buy several of the other better (and cheaper) batteries over time FOR WAY LESS. This thing is an utter disappointment overall. I regret buying it and having a hint of red under the hood is not enough to justify the cost. In conclusion if you want the name, or flare of color under the hood at any expense - get this. Essentially, "I want red in my engine bay." If you care about performance, capacity, or frugality THIS IS NOT YOUR BATTERY. DO NOT BUY THIS. This company is literally running on scams. ... show more

Great product as expected made cranking a cinch. Kit came with several mounting blocks to fit most vehicles and made installation very easy. One notable detail you may need to know is the Red top’s main priority is starting power which I do need on my Suburban but the Yellow Top would have better served my needs for towing and my Sub system. I’m still very happy with this battery. ... show more
