Battery 019 Test Report (Test Series 5)
Abstract
A fifth series of battery 019 tests were conducted from 1 May to 14 May 1976. A total of 19,927.3 AH had been discharged from the battery at the beginning of the test series. During the ten cycles conducted, an additional 2983.5 AH were discharged for a total of 22,910.8 AH at the end of the fifth test series. During the first five cycles of the test series the ambient pressure during discharge was varied from one cycle to the next. The discharge pressure was 3000 psig for the first cycle and 2,000 psig, 1,000 psig,100 psig and 0 psig on the succeeding cycles. The purpose of this procedure was to determine the effects of discharge pressure upon charge acceptance (K1) and charge efficiency (K2). All the charges during these cycles were conducted at the 60/20 rate at 0 psig ambient pressure. The ambient temperature during the entire test series was about 18 deg C. All of the discharges throughout the test series were at 105 amperes. Results of test series number 5 are shown in Table I and Figure 1. In addition values of K1 and K2 throughout the test series are shown in Table I and Figure 2. Although the value of the charge efficiency factor, K2, for cycle number 1 was slightly lower than for the other cycles K2 basically remained steady during the discharges at various pressures. There was no indication that discharge pressure had any effect upon K2. The charge acceptance factor declined with each succeeding cycle during the first five cycles as has been the case in previous test series. There was no significant change in this pattern for the first five cycles with discharges conducted at various pressures.
