Which of the listed ranges represents the specific gravity for the electrolyte of a fully charged lead-acid battery at room temperature?

🔍 Key Concepts

• Specific gravity is a comparison of a liquid’s density to pure water (which is 1.000). • A fully charged lead-acid battery has a standard, commonly accepted specific gravity range at about 77°F (25°C). • Lower specific gravity values usually indicate a discharged or weak battery; unusually high values are not typical for normal electrolyte.

💭 Think About

• Think about what specific gravity range is commonly used as the reference for “100% charged” in battery maintenance tables and hydrometer charts. • Compare each option to what you would expect for distilled water (1.000). Which option looks like a realistic, slightly denser sulfuric acid solution used in batteries? • Which ranges look more like they would indicate a partially charged battery, and which look physically unrealistic for battery electrolyte?

✅ Before You Answer

• Make sure you know that distilled water = 1.000 specific gravity at standard conditions. • Recall the typical fully charged value often quoted in textbooks and maintenance manuals for lead-acid cells (around 1.26–1.28). • Eliminate any choice with values that are clearly too low (close to water) or too high to be a normal battery electrolyte.
