| Contd. -7- EFCl/T17.10.24. The preliminary high and low rate bench discharge results of this battery have not been particularly good, but it is expected to improve with use. It is now on our bench life test, and so far is quite satisfactory. Extracting briefly from JB.41 :- "The battery as regards designm plate grids, "pasting, separators, etc., seems generally very "good. The cell cases are of ebonite and,liable "to crack. The cells are not properly located in "the containing case, so that they would be liable "to shake about. "These, and the fact that the vent plugs are "very poor as regards prevention of spraying during "charge, are the principal other faults of the "battery." It may be that the makers have aimed at obtaining life at a greater sacrifice of efficiency than is necessary. Fuller Sparta. We received a Fuller Sparta battery, type OS12/102 on 5.12.23, in a charged condition. Weight 103.5 lbs., rated ampere-hour capacity 102. As previously referred to in our report EFCl/T15.5.24 on the performance of alkaline batteries of 40/50 size, the high and low rate discharge results of this Fuller battery have been phenomenally good and consistently so in subsequent tests. It has actually been the only 12 volt battery in our experience which has given 1 ampere-hour per lb. of weight, and the high rate discharge results of the battery have been correspondingly good.
