EFC4 T20.1.26. -2- Contd. stratification of the electrolyte (whose total average density falls on closed circuit into a portion at water density at the top and a portion at larger density at the bottom. This presumably would only occur if the battery were subject to standing at rest while on closed circuit. At any rate, even if we are not right in our attempt to diagnose the trouble, it is quite obvious that the battery has not had a fair time, as there is clearly no reason why it should not have behaved satisfactorily in normal circumstances. There is perhaps one other possibility, viz. that if the battery were not charged by the makers, and this may be the case since it came from Paris, that it did not have a correct first charge. The failure is certainly not due to over-charging, the amount of sediment being practically nil. The mechanical condition of those portions of the battery which were not disturbed before reaching us was quite O.K. EFC. It would appear to be worth while having this battery repaired. Would you kindly let us know what to do with it. | ||
