The watt-hour efficiency of a lead-acid cell varies between________?
Correct answer: C. 70 to 80%
- A. 25 to 35%
- B. 40 to 60%
- C. 70 to 80%
- D. 90 to 95%
Explanation
Lead-acid watt-hour efficiency is typically about 70 to 80%, lower than ampere-hour efficiency because the discharge voltage is lower than the charging voltage.
