METHOD FOR DETERMINING AMOUNT OF WATER TO BE ADDED TO A NiCd CELL

摘要

Deficiencies in the electrolyte level of the cells (12) of NiCd battery (10) can be detected by measuring the internal resistance of the cells (12). Initially, data is collected for a battery type and capacity, correlating measured internal resistance with the amount of water that must be added to bring the cell resistance to an acceptable value. Subsequently, cells of other batteries of the same type and capacity can be measured to determine how much water must be added and the levels quickly restored. The polarization value of the cells can be used lieu of the internal resistance in the same fashion.
