| X.3398 Extract from EFC1/T18.5.20. X.664. BATTERIES. X.3398. P & R BATTERIES. We have previously reported that we have not had good results from these. The last one received (14) was described in our EFC2/T7.8.19, and the results from this battery especially the high rate discharges, have been very disappointing. All samples of P & R batteries tested have seemed to suffer from a similar weakness. It may be expressed that they do not seem to have much life in them. | ||
