Fw: (ET) battery condx

["Herb Crary" <jhcrary earthlink net>]

I bought a Battery Load Tester in Nov. 1999 from a traveling tool show. It
cost $20. It's not fancy, of course,  but I think it is worth what I paid
for it. I have mostly used it on my auto batteries. Its meter scale reads 
in
"cold-cranking amps", so it would take a bit of translation to get
ampere-hrs. capacity, but it probably would be useful enough for $20.

It is sold by Cummins Tools and is available on the Web. Anyone interested
can go to the link below and search for "Battery Load Tester". A photo is
included. Here is the link:
