III To _________ 19__ Order No. JC 37 Customer's No. _______ On discharge only 51.6 ampere hours were obtained, this is less than was previously obtained. To make sure that no snag or mistake was made it was charged up again on 17 volts & discharged as before this time only giving 50.4 ampere hours. Following this the battery was again charged at a constant current of 6 amperes & on discharge gave 56.3 ampere hours. On the last two discharges it was noticed that no 3 cell was fully discharged before the others, having a slightly smaller capacity for some reason.
