A few years ago I mistakenly left the DC/DC charger on before going on a long trip. When I returned, over a third of my pack of 45 CALB CA180s were toast. After a long period of mourning and denial, I'm ready to get my EV up and running again, but need to test the remaining 28 batteries that didn't go to 0V to determine if any can be salvaged. Are there some affordable test instruments that can do this reliably? Any advice would be appreciated.

you may need to kick start the cells with a charger, or parallel to a 'good' battery to get the voltage up to the point a cell charger will see the cell and start charging.

I've had really good luck with the Revolectrix powerlab unit for charging, top balancing, and capacity testing large capacity single cells. They are programmable for different chemistries, charge/discharge rates, etc.
