Contacted Optima to register my purchase, and they won't allow it because they say it was sold by Amazon. This is in direct contradiction to their warranty page where it's clearly written that Amazon is a certified seller of Optima batteries. So, without even needing service from Optima, I'm already behind the 8 ball with Optima, already causing problems and nonsense with their product. Do not buy Optima batteries.

the battery worked fine for almost two months. Then after sitting for a week has gone completely dead. Supposed to be a 36 month mfg. warranty but amazon makes it imposible to do a return after 30 days.

The thing I care most about in my car battery is how long it lasts, so its hard to write a review of this until a few years has passed but will give my initial thoughts here and update if it ever changes.I bought this for my 2002 Honda Accord. I had compared it to other batteries and was going to buy it local but when I looked around similarly priced batteries were not nearly rated as high. This particular battery would have cost me at least $50 more locally so I ordered it from Amazon. Shipped quickly and was at my door two days later. The packaging was in the frustration free packaging and it was indeed that. No problems that I could see and very easy to get to.Anybody who is worried whether they can do this by themselves shouldn't be. If you are at all mechanically inclined, this is the simplest job on your car you can do yourself. Just unhook the battery harness. Remove the cables. Potentially scrub them a little if they have rust. Spray on some battery protector, and hook the cables back up. I had to use the riser that was included with the battery for it to fit in my car, but that was easy and straightforward.Battery works great. Provides plenty of power and starts the car right away with no issue. Actually, this is an improvement over the battery I had before which was from AAA.

Good battery. I had an earlier version, which somehow after two years totally died completely in my 'Vette (which, honestly, is a garage queen and doesn't get driven more than a few times a month). There is a known voltage drain glitch in some manual 'Vettes with the shifter-in-reverse-to-turn-off requirement and also the remote door lock function (software fixed this problem). But, regardless of why it died, the battery wouldn't recharge at all following a jump and 50 minutes of driving - the charging voltage never settled down (probably something about the load presented to the alternator). I took it to the place where I bought it, an outfit I get my motorhome batteries from, and they couldn't get it to charge/hold a charge so they sent it to the area rep. I suspected a bad cell, but the rep was able to fully charge/hold (which I have verified these last few weeks). The battery this review is written for, is working fine in the car and I monitor the charge voltage often while driving, but the reason for so much yakking is that I was told by the rep that this cell design, once fully discharged, needs more attention than "regular' cells to wake them up.

The battery died on my Scion tC and I went straight to Amazon to find a new one. I have had an optima Red-Top in my Prelude for about 6 years now and it still runs strong (Worth it for just the winter starts alone), so I naturally went for the same battery this time. As far as the battery is concerned:......Works great right out of the box......Battery was charged enough from the factory to get the car started right out of the box.......Size and weight are very close to the OEM tC battery, It fit right in place with no mods. (Also, I do agree with the previous poster who said the terminal protector case would serve great as a booster to pick the battery up an inch or two. It's just a square piece of plastic)As far as the shipping and packing by Amazon is concerned:......First, I'll admit, I was concerned about the shipping based on what I read in the other reviews, but I know Amazon is on top of most problems pretty quickly and I was hoping they had addressed the packing issue by now. So I went ahead and ordered.......Well, as soon as I opened it up, It was obvious they fixed the packing problem. It was packed VERY well. You can see in the pictures that the used chunks of cardboard pieces sandwiched between an inner and outer layer on all four sides. No cheap popcorn or anything.......The battery arrived with no dents or scratches......Never doubt Amazon, my son.All and all....a great buy!
