Assuming that the electrolyte has had sufficient time to be uniformly diffused throughout the cell, if the open-circuit cell voltage as measured by a digital multimeter is 2.12, what would be the approximate specific gravity?

Question 1 of 27070

🔍 Key Concepts

• Relationship between open-circuit cell voltage and state of charge in a lead-acid battery cell • Typical fully charged cell voltage (around 2.12–2.15 volts) and its corresponding specific gravity range • Effect of temperature assumptions (standard reference temperature) on specific gravity values

💭 Think About

• If a single cell shows 2.12 V at open circuit and is assumed stabilized, what state of charge does that usually represent? • What is the typical specific gravity range for a fully charged lead-acid cell at standard temperature (about 80°F / 27°C)? • Compare that typical fully charged SG value to the answer choices and see which one best matches the normal reference value.

✅ Before You Answer

• Confirm that 2.12 V is treated as a fully charged cell voltage in standard reference tables for lead-acid cells. • Use a standard chart (voltage vs. specific gravity) to see the approximate SG at full charge, rather than calculating from first principles. • Make sure you are thinking about single-cell values (not a 12 V or 24 V battery) since the question is per cell.
