At first I was a little leery to order a car / truck battery from on line, but my local auto parts wanted close to double what I found it on Amazon for. So I plunged in. The battery arrived sooner than I had thought it would, greatly packed, no problem with the battery, came charged and fit right in my truck. Truck cranked right over. After a month battery still has had no issues and still looks new.

I purchased this battery for my Silverado 4x4 truck. I have a large Alpine stereo system with two amps and two 12" subs under the back seat. The truck also uses electric fans for cooling. My old battery would go dead every couple of weeks under this current drain. With this new Optima Yellow top battery, everything works great. My problems are solved.

There may have been packaging problems in the past, but not now. Battery came in heavy cardboard with all corners protected. It arrived a day early. The size was exact, all brackets & cables fit. A lifting handle works fine and stays on the battery. A plastic elevating platform, about an inch thick, was included but not needed for my Corvette. Battery was fully charged, car started right up. I have another yellow-top in an old Blazer, that Optima has worked without incident for the last two years. Very pleased.

This is replacing the same battery on my car a 2002 Subaru WRX.

PROS:

Strong battery

AGM technology > No liquid and non-spillable

Reliable power > Won't die immediately and leave you stranded on the side of the road when it's weakening.

Side posts are helpful when you have a lot of electronics going on and need another connection.

High quality construction (save for the Amazon packaging and eventual shipping damages)

CONS:

The box in which it shipped was snug and contained virtually no protection. My battery had 3 chipped plastic corners. The battery was 100% functional however.

The CA (Cranking Amps) and CCA (Cold Cranking Amps) numbers dropped a bit since 4 years ago. Not sure if Optima is making a weaker battery or just more accurate specs. It is the same item number as my old battery and that had over 800 CA and 660 CCA. This one is showing 770 CA and 620 CCA. Weird.

CCA not as high as Optima Red Top line; can be an issue if you experience very cold winters.

My battery arrived in a snug cardboard box with holes in the sides for handles. If I remember right the cardboard at the bottom extended a bit to protect it if it was dropped 3 or 4 inches straight down. After reading the reviews here, I put a sign on my door asking the delivery person to ring the bell and wait so I could examine the packaging. UPS delivered it. I don't know if they would have taken it back had I refused it because no signature was required. In any event, the packaging was fine, the battery was fine, and it works fine. This is not my first Optima. If it works as well as the last one, a different model, I will be happy.

However, I just noticed that even though this item is sold by and fulfilled by Amazon, there is a notation of no returns. I don't remember seeing this when I purchased it in January and the restriction does not appear on my invoice. This battery has a three year replacement warranty and I am wondering how that is going to work with Amazon not accepting returns. I always assumed that Amazon was an authorized dealer for items sold and fulfilled by Amazon. As soon as I find out where to make an inquiry in Amazon's maze of a help system I will report here what I find out.
