Question 248Electricity/Electronics - 1st Asst/Chief70% to pass
Which of the listed ranges represents the specific gravity for the electrolyte of a fully charged lead-acid battery at room temperature?
AI Explanation
The correct answer is C) 1.270 to 1.285.
This is the specific gravity range for the electrolyte of a fully charged lead-acid battery at room temperature. The specific gravity of the electrolyte indicates the state of charge of the battery - a fully charged battery will have a specific gravity in this higher range, while a discharged battery will have a lower specific gravity.
The other options are incorrect because:
A) 1.100 to 1.150 is too low for a fully charged lead-acid battery.
B) 1.180 to 1.200 is also on the low end for a fully charged battery.
D) 1.750 to 2.000 is unrealistically high and outside the normal specific gravity range for lead-acid batteries.
