..-- I Battery Electrolyte attacks all copper and cupric alloys, causlng copper to deposit on the negative plates of the affected cell. The first typlcal indication of copper contamination is the discoloration, a pinkish-red color, of the negative plates and straps, and as the contamination progresses, the discoloration works its way down the negative plates. This condition can quickly lead to loss of battery capacity and serious deterioration.
C. Check the cell plates of each cell for the following:
- 1. Plate growth (foreign material on the plate).
- 2. Plate buckling.
- 3. Plate or electrolyte discoloration.
- 4. Grid cracks.
