    • My car's battery was dead as a doornail
I tried jumping it, tried charging it - nothing. I've owned the car for a couple of years now and that battery was in it when I bought it (and my car is older), so I have no idea how long it was in my car prior to my purchase. So...while I wish batteries weren't so expensive, this one is right in the costs of recommended batteries for my vehicle. I also did check on the cost to have someone bring a new battery which also required I pay for installation meaning TWICE (and a little more) than the cost of this battery!!! I have very little money to spare, so...I bought this battery, took out the old battery, although I had to have help to get the old VERY heavy battery out (my male next door neighbor helped pull it out of the engine bay as I am a 70-year-old lady with no upper body strength. This battery was actually lighter weight so I could pick it up and set it on the battery plate and that is the only downside is that this battery came with a bottom that could be used on the old battery platform EXCEPT that the way my battery platform ties down is this long screwtop with a J-hook bottom that hooked into a small spot in the original battery platform and the ones that were sent with this battery didn't have any way to use it with that J-hook and screw-top piece that was NEEDED to tie down my battery. Other than that, I was able to tie down and hook up this battery very easily. I did my little prayer that the car start after hook up and my car purred to life and works so well my neighor who stopped to see how I was doing said, "You just replaced the battery?" His eyebrows up, he added, "And it's running?" My car runs so quiet even with the hood still up he couldn't hear it running! So, all I can say is while I wish batteries weren't so dang expensive, this one worked perfectly. I'm happy with it as my car is back to running - what's not to love about that? ... show more

    • Go to battery
This is and has always been my go to choice of car battery. I have full trust that when that key turns, my car is going to sing to life. They have never left me stranded. The one thing I do dislike is when they do go dead, the go DEAD. There is no recharging, there is no repairing, no fancy charger is going to bring it back That battery is kaput. It's a good thing it always get years of use out of it. Well worth the money. ... show more

    • "Upto 3x longer life" is the claim, but it is dead after just 1 year.
Bought this to replace my old battery, which I don't even remembered replacing. Since I live in Las Vegas now, and my mechanic told me that the heat and cold will shorten the battery life, I opted to buy the best one available on the market. Sadly, it first started giving me trouble after just 1 year and will not even start my car after exactly 13 months (from order date Dec 15, 2014 to January 28, 2016). Thought it was just a fluke at first when it will not start my car when I was trying to commute to work, but it was really cold that week. And since then it has struggle to start but started the engine, unless I purposely leave the car parked over 36 hours to see if it is the battery not having enough juice to start the engine. And sure enough, I only hear the clicking sound and that's it. It will start for awhile when given a jump start, but today I felt embarrassed for my car not starting after filling up at a busy gas station, since I was inconveniencing others patiently waiting in line to fill up and go about their day. Seriously expected a lot more for a battery that claims to have 3x the battery life compared to other competitors. But after 1 year and 1 month, the premium price paid for this battery seems not worth it. Especially reading all the reviews that claims the warranty is not honored at all. Anyway, 2 stars for now, but will update once I find out more from the manufacturer and Amazon. ----------UPDATE---------- This is the email reply sent my Optima Customer Care, which basically punt the responsibility of warranty claim (13 months within the 36 months warranty period to Amazon, the original retailer). Hi Tony, Warranties are handled by the original retail location with original receipt. Most retail locations register your sale with your phone number and can track that purchase. Amazon does handle the warranty on the batteries they sell; you simply need to contact them for warranty services. If you have any issues attempting to get warranty assistance please get the name of the person you spoke with and give us a call or email us. The Optima factory warranty policy requires a receipt from the original purchaser. Your purchase receipt: 1. Establishes the beginning date of service. 2. Identifies you as the original purchaser 3. Identifies that the battery is used in a consumer (not commercial) application. 4. Identifies the sale as a retail purchase. Without this there is no way to verify that the battery was purchased new, never been used. Thank you, Matt Optima Customer Service ----------END UPDATE (1/28/2016)---------- So basically, the manufacturer want s the buyer to follow up with Amazon, and come up with all the excuses (including allegations that Amazon.com actually would sell used car batteries, which is a completely laughable notion) so they will not have to honor their own warranty policy. FYI, Amazon will only assist you with this purchase if it is with the first 90 days, after that it is a struggle speaking to or live chatting with Amazon's support. Good battery if you don't end up with a lemon. Bad service from Optima Batteries, at the unacceptable level. Amazon customer service is a lot better, but you have to be firm and explain everything to them, in the hopes that an equitable resolution can be reached. Buyer beware. ... show more
