| R.R. 235 A (100 T) (S.F. 846. 6-8-19) G.{Mr Griffiths - Chief Accountant / Mr Gnapp} 2460. Contd. -9- EFC1/T18.5.20. Unfortunately we subsequently had an accident to two cells of this battery by which these two cells were blown up owing to a short caused by a watch-chain firing the explosive mixture in one of them. The other four cells are intact and will probably sometime be subjected to the vibration tests previously mentioned. We have recently received a smaller Tudor battery (33) made up of dimensions similar to the 6 BXE 5 Chloride, suitable for the rear of frame position. This battery has also shown up very well on test for its size and weight (77lbs). It has good filling holes, vent plugs, separate cells and very good terminal connections. The cell to cell connections get slightly warm on the high rate discharge test. A comparison of the internal resistances of various batteries comes out in the initial value of the discharge amperes through the fixed resistance on the high rate discharge test. We shall again be writing the Tudor Company to let us have more of these for test in the rear of frame position. CHLORIDE BATTERIES. Further to our EFC7/T20.4.20, we have arranged with the Chloride Company to supply us with two further BXE 4 type batteries of size suitable for rear of frame position, and they are going to take particular care with the separators of these to absolutely avoid the fault which came out on the 10,000 mile test.
