We beg to acknowledge receipt of your letter of the 12th instant. We note your proposal to utilise a standard 6-XCL3-1M battery fitted with 11 plates per cell, 1/8" thick. This would result in a battery similar to the 6-XHR11-1L type suggested in our letter of the 4th instant, but utilising a plate pitch of 7/16" instead of 1/2". A reduction in overall length would thereby be obtained, together with a small reduction in weight, but it should be noted that the capacity would also be reduced. Our standard XCL3 elements could be fitted as emergency replacements. We should not actually be able to use our existing 6-XCL3-1M container for this battery as this is not suitable for use with a cover, but we would use a special container of general-ly corresponding dimensions. Your proposed battery would actual-ly be a 6-XHR11-1L type with 7/16" plate pitch, and would therefore be similar (except for having 11 plates per cell) to the 6-XHR9-1L battery which we have supplied to you for the Bentley chassis, and which also uses a 7/16" plate pitch. We feel, however, that if you can accommodate the extra dimensions of the 6-XHR11-1L battery with 1/2" plate pitch, put forward in our letter of the 4th instant, it would be well worth while to do so from the technical stand-point. We give below the technical data for the | ||
