That's exactly what I am implying. I would tend to favor DEKA if they still make all their own batteries. A phone call to Pennsylvania would resolve that. On average the construction therefore the life-span of car jar batteries has tumbled the last 10-years. But then again 30-years ago I found through trial-and-error RAMCAR batteries which were manfactured in the Philippines to best by far the best of made-in-USA starting batteries. This is exactly why I presently have very deep suspicion about the integrity of using recycled lead. The Ramcar Philippines battery used pure virgin lead and just beat the heck out of made in USA Ramcar batteries for number of warranty rejects. This involves thousands of batteries.
Deka is the sole USA OEM that has their own lead refinery. They may or may not use processes to render their recycled lead to a higher level of purity. If you want to yank on a battery manufacturer's family jewels than to stick your nose into the degree of purity of base stock lead. It costs a lot of money to recycle lead and a frightening amount of money to render it more pure than ninety eight and high points percent pure. To me this is a voodoo area and OEM engineers like nothing better than to ignore or divert questions away from the subject. Mexico recycles very little lead because the country is overflowing with lead mines. The LTH battery has had an excellent reputation warranty wise. It is curious that Optima batteries are made in Mexico and that ALL AGM manufacturers make a big deal out of their guaranteeing of using 100% virgin lead. None of this is coincidence. Most curious...
