y 4288 COPY OF LETTER RECEIVED FROM:- THE CHLORIDE ELECTRICAL STORAGE CO. LTD., CLIFTON JUNCTION, Nr. MANCHESTER. ECM-LB. 6th February, 1922. Messrs. Rolls-Royce Ltd., Nightingale Road, Derby. x4288 x 130 Dear Sirs, Starter Batteries for 40-50 Rolls-Royce Cars. We beg to remind you that our running contract for the supply of "Exide" Batteries, 6 BXRE5 type, has now expired, and in anticipation that you desire to enter into a new contract, we beg to inform you that we are willing to give you the advantage of the fall in price of various component parts, and particularly the recent remarkable drop in the price of lead. We do not suppose that this present low figure will be maintained very long, but if you can place a contract with us now, we can take advantage of the low market, and in such circumstances are willing to enter into a contract with you for the further supply of batteries, 6 BXRE.5 type, at a price of £7. 5. 0 (Seven pounds, five shillings) per set. At this price we can supply the batteries in a fully charged condition direct to the Coachbuilders, if desired, either from our works at Clifton Junction, or from our London Dept. Our mutual experience with batteries on your cars has, we feel, very clearly demonstrated that a larger battery is desirable in most instances. Irrespective of any modifications which you decide to make in the charging equipment, and which modifications would undoubtedly be beneficial from a standpoint of battery life, for town work a larger lighting capacity than that obtained from the BXRE.5 appears to be desirable. We have, therefore, taken the liberty of to-day sending you one of our 6 XHR 6 batteries to examine and test. This set has a capacity of 90 ampere hours at the 20 hour rate of discharge compared with 55 ampere hours of the BXRE.5, has a cranking ability of 105 amperes for 12 to 16 minutes to 1.7 volts per cell; has a normal charge rate of 6 amperes; and measures overall 7 3/16" x 22¼" x 9 5/16". | ||
