Excessive charging a battery tends to____________?
Correct answer: D. bring about all above changes
- A. produce gassing
- B. increase the internal resistance of the battery
- C. to corrode the positive plates into lead peroxide thereby weakening them physically
- D. bring about all above changes
Explanation
Overcharging decomposes water and causes gassing, raises internal resistance, and accelerates positive-plate corrosion and weakening. Since all three effects are associated with excessive charging, option d is correct.
