abunda_amazon_reviews I'm amending this review to add this header. CHECK THE DATE OF THE REVIEWS BEFORE FORMING AN OPINION. Take note of the YEAR of the reviews. I wondered why there were so many 5-star reviews and 1-star reviews. Clearly something changed with Optima's quality and warranty since 2017. I was tired of dealing with corroded cables and conventional lead acid batteries, so I decided to bite the bullet and get Optima batteries for my cars and Camper. I purchased a yellow top in February of this year. That's right; OF THIS YEAR. I spent a ton of money on a battery that I expected to do the job, not be finicky about multiple charge/discharge cycles (since the truck and camper sits for long periods) and be the end of my messing with batteries. Well; That didn't turn out to be the case. The battery ran down after a couple of weeks of non-use. At first I thought the truck had a problem. I charged the battery, tested for current draw, and found nothing significant to worry about. This happened for about six cycles before I decided to just remove the battery and charge it on it's own, with a smart charger. At first I would see that the battery was charging, then a fault code would appear. OK; I decided maybe it was the charger. I used a "dumb" charger and timed a cycle of four hours, to get it going, then put the other charger back on. I set the current low (2 amps) and after 24 hours or so, it showed "Full". I put it in the truck, It lasted a few DAYS and ran down again. I charged it again and noticed that one side of the battery was getting warm and the rest of it was cool. In the mean time, I put an older, known good lead acid battery in the truck. After three weeks, no problem with the "old" battery. So I decided to contact Amazon about the warranty. Amazon says, contact Optima. Optima says "try recharging....." I'm sick of the runaround and getting garbage for high prices. I'm sick of Amazon and of Optima right now. If you think spending a lot of money for a "premium" battery, like Optima is a good move, let me tell you; It isn't.;;Reviewed in the United States on December 22, 2018;;1.0 out of 5 stars;;Very Disappointed;;George M. Dudash;;/gp/customer-reviews/R3HEREAZSPXLJ1/ref=cm_cr_dp_d_rvw_ttl?ie=UTF8&ASIN=B000MSBUA4;;;This is not a review for the Optima battery, but more-so for Amazon's policies about replacement. BEWARE! If you purchase a battery and try to get it replaced in the 36 month warranty period through Amazon and they the product has gone unavailable, they can only offer you a refund. That would be good, except after 2 years of having the battery, the price has gone up. I would suggest buying this from Autozone and you can just go in and get a new one the same day for warranty replacement.

I bought this may of 2017. When it came in their was not a production date sticker on it, who knows this could have sat on the shelf for 3 years before it was shipped to me. Won't hold a charge after less than a year.

I began find that my truck would not start. At first I thought it was because I left my ham radio on overnight. So I charged it back to 100 percent with an external AGM smart charger (pulse charge, pulse charge, etc.). I don't drive every day because I telecommute for my job, or I'm driving a rental car out of town. Each time I left my truck sit for a few days it would not start; I had to charge the battery to get my truck started. I discovered that the battery would lose 20 percent of capacity during the day, just sitting unused. Now a few months later, it will charge only to 62 percent. Amazon just ignores my requests for adjustment. I have a four-year-old Optima battery that continues to function well.;;Reviewed in the United States on November 29, 2016;;1.0 out of 5 stars;;Not the Optima Battery That These Used to Be.;;MMMMMM;;/gp/customer-reviews/R10SNOT9YRCZY3/ref=cm_cr_dp_d_rvw_ttl?ie=UTF8&ASIN=B000MSBUA4;;;I've always used these batteries without problems but this is less than a year old and it looks as if it's going to explode. It's bulging. I understand sometimes you get a dud but I can't find anywhere on Amazon's site to warranty this thing. So I guess I'm 200 bucks.

I first thought it was an expensive good brand, but it was not. The battery defect and fail with less than two years, I lost my received, and there was no way for me to return for warranty. I called customer service direct line Optima, but they refused to help me, and this lady hanged up the phone on me. But if you buy from Amazon, the service is the best, however, I would stay away from this expensive battery which lasted less than 2 years for me.;;Reviewed in the United States on June 18, 2018;;1.0 out of 5 stars;;I first thought it was an expensive good brand, but it was not;;Amazon Customer;;/gp/customer-reviews/R2B1GZDEI02CHF/ref=cm_cr_dp_d_rvw_ttl?ie=UTF8&ASIN=B000MSBUA4;;;Great battery, horrible delivery!!!!;;Reviewed in the United States on July 15, 2016;;5.0 out of 5 stars;;Beware of possible damage upon delivery!!!;;Daniel;;/gp/customer-reviews/R3D07F0PUJ7NB1/ref=cm_cr_dp_d_rvw_ttl?ie=UTF8&ASIN=B000MSBUA4;;;this is the least expensive site ive seen for these and its well worth paying more for an Optima than a regular battery , its all i have used for 15 years, i currently have 4 of them in use, all yellow tops , one of them is 9 years old and still checks fine with my battery load tester, no battery last forever but whenever one of them dies i replace it with another Optima, they have always out-lasted the warrantee , there is NEVER any acid mess , you can mount them at any angle and shake them off roading and not worry about them leaking or comming apart on the inside and losing power like a regular battery can;;Reviewed in the United States on April 19, 2015;;5.0 out of 5 stars;;best batteries ever !;;Bret;;/gp/customer-reviews/R1IONF8PJOO08R/ref=cm_cr_dp_d_rvw_ttl?ie=UTF8&ASIN=B000MSBUA4
