If you're expecting a battery to put out xx amps into a starting load, and it only has half that capacity let...? Same same?
I thought they were measuring internal conductance and the price had just ramped down because they were a little less sophisticated, lower power rated, and some electronics had dropped in price.
Not sure which new meters you're referring to. Can you be specific about makes/models? Have you tested or used any?
The good ones still cost a bundle. My MDX-650 still costs $650-$750 new. The cheaper ones that I've seen all have some limitations.
But, hey...it's always possible. The Chinese have a "conductance tester" that sells for $10 :-)
