2 JD{J. Draper - Frames}102. The P&R had the greater capacity. On High Rate Discharge Initial amperes = 104.3 Time to 104 " = 2.6 min " " 100 " = 8.5 " " " 90 " = 18.0 " " " 84.5 " = 20.0 " The P&R was the better on this test also & the Exide shewed positive weakness. No 1 cell in the Exide unit was worse than the other two. The Cadmium readings are as follows. P&R.{Sir Henry Royce} Positive .20 Negative .35 Exide No 1 cell.
