Wondered if anyone had experience/opinions of the Midtronics Celltron 
battery tester as seen at

The publicity is fairly convincing but you can't beat first hand 
knowledge. Since I'm currently mothering a dozen batteries taken out 
of various cars and tractors for the winter it's something of more 
than passing interest.

Thanks.
