| X46178 To Wd. {Mr Wood / Mr Whitehead} from EFC. {E. Fowler Clarke - Electrical Engineer} EFC {E. Fowler Clarke - Electrical Engineer} 4/T21.6.26. RE CHARGING P.D's of EXIDE BATTERIES. X46428 We would like you to write to The Chloride Electrical Storage Co. to enquire if they are doing anything with a view to reducing the charging terminal potential differences of the two standard batteries which they supply to us. As you may know, Messrs. Peto & Radford are working on this matter and according to their latest reports they are succeeding in reducing this quantity, but as a matter of fact - and as confirmed by our most recent observations - the present standard P & R's are both higher than the present standard Exides, and the amount by which they are reducing them would bring it down approximately to the figure for the Exides, so that in reality we cannot so far as we know at present expect very much smaller figures for this quantity in the case of the Exide batteries. Still, to be in line with what the other people are doing, we think there would be no harm in enquiring as to whether they consider they have reduced this quantity to the minimum obtainable. EFC. {E.
