Hi,
Seems the old ways to test a car battery with a dvm or load tester have been superseded by these "conductance " devices which would appear to be micro based.
**broken link removed**
Can find little about their circuitry as was wondering if the actual battery testing part of it was diy buildable to work alongside a DVM ?
Seems you also need a table etc to apply to the measurments to give the correct result.
Just that the price of these meters is almost the price of a new car battery , so not very cost effective for a one car family.
