Cycle Numbers

1. LIFE CYCLING STARTED AT VT 4.0 (1.380 V/C].2. VT'S WERE INCREASED FROM 4.0 TO 8.0 IN 112 VT INCREMENTS DUE TO LOW

EOD'S AND • RECHARGE.3. A PERCENT OF RECHARGE INCREASE WAS NOTICED AFTER EXTENDED OPEN CIRCUIT

TIMES DURING CHAMBER PROBLEMS.4. CYCLE #3840, IT WAS NOTICED THAT ALL CELL CASES WERE SWOLLEN DUE TO

HIGH PERCENT OF RECHARGE (117_].5. CYCLE #6073, PACK SLIGHTLY RECONDITIONED WHEN TEST SYSTEM WENT DOWN.

VOLTAGE STEADILY INCREASED THE NEXT 25 CYCLES AND THEN DECLLINED.
