| To By/HM.{Capt. W. Hallam - Head Repairs} from EFC. X8782 EFC2/T16.4.26. P & R BATTERY EX CHASSIS 36-HC. (BY/HM{Capt. W. Hallam - Head Repairs}3/G5.3.26) We have now completed examination of this battery and herewith please find copy of my assistant's report AC.20. Though it is not impossible that this battery had suffered from an internal short circuit which became removed in the act of emptying the battery, we consider it very unlikely that this was the case. The fault with the battery appears to have been that it had been filled with acid much too high density; the density of the acid received in the bottle, as purporting to have eat come out of the battery, was 1300, in addition to which there was, as we proved by water charging, considerably further sulphate element on the plates. It is not possible to remove the sulphate element from the plates into the electrolyte by charging when the acid density is above a certain figure, and in that case, the elements of the battery would work unsatisfactorily. Therefore, we must ascribe the unsatisfactory working of the battery to faulty treatment in the matter of electrolyte, it being a fact as reported in the attached report, that we have been able to get the battery by suitable treatment into a very satisfactory working condition. Will you please give us the necessary instructions for disposal of this battery which is really now in quite good condition. Though we do not usually send batteries away from the Works in a charged condition (we receive them in a charged condition) it would be a pity in this instance not to be able to send the battery to the customer in its present condition, as it is not desirable when it can be avoided to treat the battery in the way described in the Instruction Book to render it suitable for transit, especially as this involved another first charge at the other end. If you can, therefore, make arrangements for the despatch of this battery (at owner's risk) duly filled with electrolyte, this would be a better way. As we understand the matter, a special concession would be necessary from D.{John DeLooze - Company Secretary} to enable this course to be adopted. JC.20 attached. EFC. | ||
