Hello, I noticed your conversation and wanted to offer some assistance. There is quite a bit of information to cover, so I apologize in advance for running long. While we did eliminate pro-ration from our warranties, the free replacement period on our warranties has only been increased over the years. If any battery fails from a manufacturing defect, it is likely to do so well within the first year of use, if not the first month.
As ugexe suggested, many of the “bad” batteries returned to us now are just deeply-discharged and work fine, when properly-recharged. As Rick indicated, many battery chargers will not recognize or charge any battery that has been discharged below 10.5 volts. This is a charger issue and not unique to Optima. Some manufacturers have dealt with this issue by simply voiding the warranty on their batteries if they are deemed to be deeply-discharged. We decided a better alternative was to explain to folks how these batteries can be recharged, by using this
parallel charging technique
Since toypaseo mentioned the “g” word, I should clarify that our batteries are AGM batteries and can be treated and charged just like a regular lead-acid battery under most circumstances. However, “gel” or “gel/AGM” charger settings should be avoided. All lead-acid batteries will sulfate if left in a deeply-discharged state below 12.4 volts. That makes a quality battery tender or maintainer an excellent investment for any vehicle or battery that only sees occasional use or has a high parasitic draw.
The quality of our batteries has always been excellent and has continued to improve, since we were acquired by JCI in 2000. We still use 99.99% pure lead in all of our batteries, which is fairly amongst AGM manufacturers and while I cannot speak for other manufacturers, we all strive for a zero defect rate. The degree of automation in our current production process has resulted in even more consistency and reliability in our products. You can watch a video on this process
here.
Although we are owned by JCI, we produce all of our own batteries in our own facility and they are the only batteries produced there. We never re-brand or re-spec our batteries for anyone. Some retailers do have exclusive contracts with battery manufacturers, but other customers, including our military, source their batteries from multiple suppliers (including us) for a variety of reasons.
It is fairly common practice for all retailers to offer warranty service only on the products they sell. If you purchase an ipod at Sam's Club and take it to Best Buy for warranty service, they'll probably suggest you go back to Sam's. Batteries are no different in that regard and many of our retailer partners do have hundreds or even thousands of locations spread across the country.
Since many of you run winches, I should mention that RedTops are designed and warrantied for starting applications. If you are running a winch or other significant electrical accessories, we strongly recommend a YellowTop, which is designed and warrantied for deep-cycle use, including winching. Many people can get hung up on a battery's cold cranking amps and that is important if you live somewhere cold. However, reserve capacity and a deep-cycle design is far more important for batteries used in deep-cycle applications, as long as the cranking amps meet or exceed the OEM specs.
Nasty350LT1, I'm sorry to hear about the problems you had with your battery. What were the circumstances surrounding your issues? Was your Z28 a daily driver? Based on your screen name, is it safe to assume you did an LT1 swap in this vehicle?
Tbars4, Foxracin, LBarr2002, BrianDye, celly, Anime, rookieshooter, gmanpaint, Rick, RickOTR, and 1ATony, I'm glad to hear you are all pleased with your Optimas. We are always collecting Optima stories, so feel free to
share your story with us. If anyone has any questions about our batteries, I'll do my best to answer them.
