E.J.B. JD{J. Draper - Frames} 63 x 7535E. 19-3-30 X7535E X7536 Tests on Exide 3RRS-1EL-3-4 Battery (21/2) This battery has now run 12,009 miles on the road. A central connector F31450 was fitted with this battery but was not properly lead coated, this has now run 4,768 miles & is in perfect condition. On Low Rate Discharge 71.1 ampere hours were obtained. All cells showed positive weakness. On High Rate Discharge Initial amperes = 105.2 Time to 1.04 " = 4.0 min " " 1.00 " = 11.0 " " " .90 " = 20.0 " All cells showed negative weakness. G.F. | ||
