Date: 2-11-1925 Order No. JC 140 Customer's No. X 4617P Re Tests on PcRRR11-3 Battery (182) This battery is now 2 years old & has run 3166 miles. On Low Rate Discharge through a constant external resistance of 1.80 w a capacity of 88.9 ampere hours were realised. All cells showed positive weakness. On High Rate Discharge through a constant external resistance of .100 w Initial amperes = 110.7 Time to 104 " = 18.6 min " 103 " = 20.0 " All cells showed negative weakness. The above results are an improvement on previous tests taken & no doubt this battery is now at the prime of its life. Signed: G.J. This Sheet must be filed on completion of the work. | ||
