The ampere-hour efficiency of a lead acid cell is normally between_________?
Correct answer: D. 90 to 95%
- A. 20 to 30%
- B. 40 to 50%
- C. 60 to 70%
- D. 90 to 95%
Explanation
Lead-acid batteries have a high ampere-hour efficiency, normally around 90 to 95%; their watt-hour efficiency is lower because of voltage losses during charging and discharging.
