NWES sells 600 to 2000 AHR batteries will these units test in that range?

Just because someone buys a damaged battery on eBay that later needs replacing means nothing. To say "the battery industry is working on a reliable device" sounds like this person is unfamiliar with this type of equipment. There are several analyzer manufactures building high tech models. Some models cost over $7000. I doubt they would have a market if there operation or value was questionable.

What I can say is that we had a battery that looked like it was melted down, I'm talking about lead terminals that were drooping and melted!! They were cooked and starved of electrolyte! We replaced the batteries, but some how the cooked batteries got into the hands of a guy who had an impedance analyzers. He cleaned them up and did some testing and claimed that the batteries were all OK. Not long thereafter, the cooked batteries showed up on eBay. Not too long after that, we sold replacement cells...you be the judge. The battery industry is working on a reliable device that makes it much easier to determine the health of a battery, but I think it is hit and miss at this point in time. Rob
