| E.L.B. J.D.75. X.46175 24-4-30 X46175 Tests on SX Battery (157) This battery has been on our bench life test for 26 months & has run 13,787 miles. On Low Rate Discharge 35.3 ampere hours were realised. All cells shewed positive weakness. On High Rate Discharge Initial amperes = 107.0 Time to 104 " = 4.0 min " " 100 " = 6.2 " " " 90 " = 10.3 " " " 80 " = 12.1 " All cells shewed slight positive weakness. No 1 cell has the poorest capacity & was originally in S2 battery. GJ | ||
