| X3398 Extract from - EFC1/T6.9.20. X.664. RE BATTERIES. We have your note R8/G4.9.20. The matter of these failures is very much before the Chloride Company as we paid them a visit on Thursday last which we are reporting separately. We are now arranging with Mr. Hives to put on the experimental cars other batteries, namely, the following. no.40. P & R type H.D.E.13 ebonite - Weight 107 1/4 lbs rated ampere-hour capacity - 60. X3398. This we think should be a reasonably good battery. | ||
