[RE-wrenches] FW: Battery impedance analyzers

[Dana]

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

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.

Hi Dana,

 

I have no direct information as to their abilities.

 

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
