If a lead-acid cell is discharged below 1.8 V the following will happen.____________?
Correct answer: D. All above will occur
- A. Capacity of cell will reduce
- B. Sulphation of plates will occur
- C. Internal resistance will increase
- D. All above will occur
Explanation
Deeply discharging a lead-acid cell promotes sulphation, reducing usable capacity and increasing internal resistance. Thus all three listed effects occur when discharge goes below the recommended limit.
