The Tudor Accumulator Co. Ltd.,

Matthew Park Street,
Westminster,
London, S.W.1.

Dear Sirs,

RE TWELVE VOLT BATTERIES

Will you kindly put on order the accumulator composed of six cells, to your quotation to Messrs. W.T. Glover & Co.Ltd., of Manchester (E.2053) but before putting the work in hand, will you kindly send an outline of what you propose the size of the cells will be, and the method of joining them together, also the maximum current they will bear during charging.

I think it will be unnecessary to send a man so far to burn the sections together, assuming that you can burn the plates belonging to each cell together, and they can be transported satisfactorily, and that the cells can be coupled together here by suitable bolts which can be kept from corroding by varnish or vaseline.

I am anxious for you to submit to the Rolls-Royce Works at Derby, a design of a 12-volt portable battery suitable for carrying on a car for the purpose of starting the engine and for lighting the car. The particulars for this, we believe, you have already received from the Rolls-Royce Experimental Department at Derby.

Contd.

H.L. 238A (500) (S.D. 26-4-17) Bm. 2/155/13.
