| To Wd.{Mr Wood/Mr Whitehead} from EFC, X3830 EFC3/T23.4.26. Herewith we hand to you for return to the makers, package containing in a now dry condition the sample Tungstone cell which we recently had. We do not think we have anything to gain by further observation of this. During the last week or two the positive plates have become so badly buckled (in ordinary charging without any serious overcharging) as to put the cell out of action. As originally surmised, this type of cell is not at all on the right lines from our point of view. EFC. Cell herewith. | ||
