I've been amusing myself going through some old batteries, load testing and checking resistance with a Battery Beak. Newer batteries had 0.018 ohm resistance. There were several marked "Practice Only" with 0.030 ohms resistance that dropped down to 0.018 ohm once I swapped out the battery cable and cleaned up the mating surfaces of the terminals with a wire brush.
