-7- Contd. "Battery troubles are undoubtedly common after "a few years use. Except in cases where trouble is "experienced in a comparatively new car, I think the "majority of owners and drivers accept this as an inherent "weakness and make their own arrangements for repair or "replacement. Nothing would consequently be known at W. "In cases of complaint of battery failure I always advise "the owners to take up the matter direct with the "manufacturers." Commenting on his second par. and in particular the phrase "except with the Phantom", we are advising him in this connection that that clause should have been [text struck through] "excluding the Phantom." [handwritten above 'have been': not have been inserted] Mr. D.{John DeLooze - Company Secretary} says :- "There is doubt whether owners are easily "able to keep their batteries fully charged. To appreciate the conditions you have to divide the 40/50 HP. cars into Silver Ghost and New Phantom types. Taking first of all Silver Ghosts, I think certainly there is a difficulty for drivers using their cars almost exclusively in town, to keep the batteries charged. They have little opportunity unless they get a week-end run, of doing any charging and their week-end run, as likely as not, will be merely to golf club and back, possibly 30 or 40 miles each way. With new PhantomCodename for PHANTOM I type cars, we have not yet enough experience amongst the delivered cars to say anything, but I anticipate that as the charging speed is so much lower, we should have less of the trouble experienced by town users of the Silver Ghost type. Taking now the 20 HP. I can call to mind a few cases where the cars, having been used all the week in town, are dependent also on a week-end run for a good charge. Unfortunately the dynamo output at speed on the open road does not enable this charge to be given and I have heard it suggested that the charging speed in the 20 HP. should be lowered, so that some charging can be done on ordinary town work.
