   @dvl I wonder which battery was completely failing under load that caused this? I'm also not sure how to actually test that because you could very well have some reliable batteries you're about to recycle.

     @feld @dvl @SlicerDicer A dead battery that fails immediately after getting put under a load probably doesn't hold voltage and might have higher internal resistance. That's how I would check it. Alternatively putting a small load like a few 12 volt halogen bulbs and watching the voltage might also do the trick. A dead battery should drop voltage quicker than others.
