To Order No. Customer's No. U as above, gave results as follow:- No of cells | Volts | Resis an't | d.c. amps. | a.c. amps. 1 | 2.3 | Both | 6.1 | .85 1 | 2.27 | L.H. | 3.0 | .75 1 | 2.28 | R.H. | 3.2 | .80 2 | 4.6 | Both | 5.8 | .82 2 | 4.5 | L.H. | 2.85 | .70 3 | 6.8 | Both | 5.35 | .79 4 | 9.2 | Both | 4.75 | .73 4 | 9.0 | R.H. | 2.4 | .60 Next the swindling link was thrown over as recommended for charging from five up to seven cells. This automatically puts one of the resistances out of action. Signed This Sheet must be filed on completion of the work. | ||
