I'll try to get this right, but some of the background info regarding Optima history may be off by a year or two.

First: 4 star rather than a 5 star rating. The warranty would need to match the longer warranties offered by others, and quality control tightened to earn five stars. Performance is normally excellent, so why not offer a longer warranty?

Gates Tire and Rubber invented/ designed/ developed the Optima and Genesis AGM batteries in the '80's/ early '90's. As I understand things, the Optima was intended for rugged/ abusive applications requiring the highest starting current, while the Genesis was intended for more sedentary uses and maximized charge/ volume by using flat plates. Both minimized venting and maintenance requirements.

The Optima brand was spun off to a Swedish company but the batteries continued to be manufactured in Aurora, CO. Johnson Controls purchased the Optima brand in ~2000 and continues to own the brand. All mfg was moved from Aurora to a suburb of Monterrey, Nuevo Leon, around late 2007. Genesis was spun off to Enersys, which used YAUSA to mfg these in China, Mexico and who knows where; I believe their premium Genesis EP series are made in Warrensburg, MO.

Optima Red Top battery design changed sometime in 2007. Apparently the glass mat was often pinched/ crimped leading to premature shorting and failure. Ratings of the 34/78 Red Top was reduced from 55 Ah to 50 Ah, the CCA rating remained at 800, and curiously, the warranty was reduced from 3 yr free replacement + 3 yr prorated, to 3 yr free replacement + 0 yr prorated. This roughly corresponded with moving the production to the Monterrey suburb, although a number of the newer style batteries were still made in Aurora in 2007.

I bought my first Optima battery for my '96 GMC C1500 with a vortec 5700 in 1998. This battery has been through all kinds of weather from New Mexico to 4 years in Germany, a couple years in Seattle, and the last 4 years in TX. I have drained this battery dead at least 4 times and it recovered/recharged every time except for this last weekend. My truck has been parked for most of the last month since the a/c is out and the temps her in TX have been 100+ for the last 2 months. I finally killed it for good... after 13 "short" years of life. I have replaced the batteries in all 3 of my vehicles with Optima's since then and will be buying another Optima for my truck. I'm sure this battery will outlast the truck this time. I'm SOLD!!!!

Below is a copy of the email I got from Optima regarding a battery purchased from Amazon.
So be aware the money you are thinking you are saving maybe costing you big time. You should also know that for marine batteries Otima is strongly reccomending the use of there $200 charger to keep them charged properly.


Hello John, is not an authorize online OPTIMA retailer, We do not know where they acquire the OPTIMA batteries nor does honor the OPTIMA warranty.

I bought this battery from a local Optima dealer on January 2008. It died on August 2009.

Since it comes with a three year warranty, I tried to get it serviced under the warranty by calling the Optima 1-800 number. Customer service agent was very rude and kept telling me I'd have to pay a fee in order to get my battery serviced.

Bought my first Optima Red Top back in 2004 to replace the standard battery in my 95 Jeep Grand Cherokee. I've just replaced that Optima (11/2011) with another Optima Red Top because the signs of battery weakness was rearing its ugly head, signs like:
high volt meter readings (consistently high 14~ volt readings) that stay high after driving for nearly an hour (13.5~ volts is what a normal reading should be after driving awhile), voltage dropping close to the danger point (11.5 volts or lower) while cranking, not being able to be "topped off" with a maintenance charger overnight. This battery has never stranded me but the signs were there.

The original Optima Red Top was never pampered, my Jeep would sit in the driveway sometimes for 2-3 weeks straight while I used a more fuel efficient vehicle. The Jeep's 5.2 V8 runs extremely well for having 203K miles on it, that would be the main reason why the original Red Top lasted as long as it did, it never had to work too hard to start engine. On top of that, I've lighten up the load even more by replacing almost all of the interior incandescent bulbs (even the instrument panel bulbs) with LED replacements.

I'm extremely paranoid about being stranded with a dead battery because I still take trips with the Jeep deep into the national forests where there is no service station or tow trucks, that why I replaced the original Red Top with another Optima Red Top, I hope this one lasts as long as the first one.

Longevity tips for you Optima Red Top owners:
Never let your battery go completely dead (below 9.5 volts) and stay there, sulfation of the lead cells will happen.
Like the other reviewers say, disconnect the battery if you are going to store the vehicle for an extended period.
