What should be kept in mind when you check the specific gravity of the battery electrolyte with a hydrometer?

Question 1 of 27070

What should be kept in mind when you check the specific gravity of the battery electrolyte with a hydrometer?

🔍 Key Concepts

• specific gravity as an indication of battery state of charge • effect of adding water to a battery cell before taking readings • influence of temperature on hydrometer readings

💭 Think About

• If you pour water into a cell and then immediately use a hydrometer, where is that new water likely to be in relation to the acid mixture? • Does temperature usually affect the density of liquids, and would that matter when you are measuring specific gravity? • Which statement in the choices clearly conflicts with basic principles of how density and floating indicators work?

✅ Before You Answer

• Compare which options are saying something is always true versus never true about temperature or indicator position • Think about whether recently added water would mix instantly with the electrolyte or sit near the top and affect the sample • Eliminate any choice that ignores basic liquid density behavior (how float-type instruments work)

Question 1 of 27070

What should be kept in mind when you check the specific gravity of the battery electrolyte with a hydrometer?

the battery is fully charged when the indicator floats low in the electrolyte

any water that has been previously added to the cells will dilute the solution and give a false reading

a hydrometer reading is inaccurate if taken immediately after water is added to the cell

temperature has no effect on hydrometer readings
