[RE-wrenches] FW: Battery impedance analyzers

[Larry Crutcher, Starlight Solar]

Dana,
That was a strange response you got. 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.
