| Contd. -4- EFC6/T4.9.24. Quoting from my assistant's report JB.34:- " The box sides are made of wood, but sheet iron "is used at the ends and a steel spring arrangement is "fixed at one end so that the battery can be a tight "fit in the box instead of using packing pieces. " The handles are fixed to the sides of the box "instead of at the ends as is the usual practice - this "makes the battery much easier to carry, but the handles "are of a poor finish, having sharp edges on them which "cut the fingers. " The connecting links are of the burnt on type, but "are hollowed out underneath, making them look of a "larger cross-sectional area than they really are. " The terminals are of the taper pillar type as "used on the 20 HP. chassis battery." The high rate discharge results of this battery have not perhaps been quite as good as those of all the other batteries mentioned above, which have been fairly consistently round about our specification of requirements more or less, this, however, containing ebonite separators not being generally quite as good on high rate discharge as we should like. Batteries of this type have not gone far enough in the various tests to form an opinion on their value relative to standard. Before, however, a battery of any new type can be seriously considered as an alternative standard, it must conform in every detail with our up-to-date specification, to which the present standard P & R battery conforms, and to which the Exide battery will conform. EFC. When brought into line with the P & R.{Sir Henry Royce} Batteries which do not conform to this specification are only tested on the bench - not on chassis. This similarly applies in the case of batteries of 40/50 size. EFC. | ||
