| HIGH RATE DISCHARGE CURVES OF VARIOUS BATTERIES FOR CHASSIS LIGHTING AND STARTING AXES LABELS: AMPERES VOLTS MINUTES CURVE LABELS: WILLARD S.J.R.27 (82 1/2 lbs) CHLORIDE 6.BXE.5 (e) (82 1/2 lbs) TUDOR P H R 7 (90 lbs) R 7.1 (77 lbs) NOTES: All batteries were discharged through the circuit of constant resistance .076 ohms. The curves are therefore curves of terminal volts to a different scale.
