Abstract
State-of-the-health analysis of Nickel-Cadmium aircraft batteries rejected as being unsatisfactory by CF bases has shown that most of the problems encountered can be related to the fact that the KOH concentration in the cells is too low and/or the carbonate concentration is too high. Exchange of electrolyte restored the performances of the cells but is time consuming, one to two weeks for a battery according to the charge-KOH exchange-discharge procedure. The present technical note describes some of the tests performed and a procedure for rapidly exchanging the electrolyte in 22 AH Nickel-Cadmium Aircraft Celgard Cells.
