It's a way to test the electrolyte with a barometer. They are avail. at auto parts stores. They have floating balls like the ones for radiators.

Electrolyte of sulphuric acid to a specific gravity of 1250.
Battery electrolyte consists of sulphuric acid, which is a liquid to a specific gravity of 1250 g/L.
By using refractometer or Hydrometer
Check the specific gravity of each of the cells in the battery. If one is low then put a rapid charge on the battery. If the cell comes back to normal then wait about 10 hours and check the specific gravity again. If the reading is low again you have a cell that is shorting out inside the battery case. Time to think about buying a new one.
when a battery is fully charged , the amount of sulfuric acid mixed with the water is sufficient to give a specific gravity of about 1.3 when battery is discharged to 50 percent, the specific gravity reading should be 1.2 any specific gravity reading that's less than 1.1 usually indicates a dead batteryThe answer isC. 1.3.
Possibly. Depends on the specific battery.
a battery and a toy car..........................
When a battery is fully charged, the amount of sulfuric acid mixed with the water is sufficient to give a specific gravity of about 1.3. The answer is C. I found this on Page 78 of the Mechanics Study Unit of Physical Science (Penn Foster). One of the uses of a hydrometer is to measure the condition of electrolyte solution in a storage battery of the type used in a car. When a battery is fully charged, the amount of sulfuric gravity of about 1.3.
Any auto parts or auto specialties store will have a device - or a choice of devices - that will do exactly that . They are not expensive. <><> Device is a hydrometer.
That's a 'hydrometer'.
Known as a hygrometer. May be as simple as a few beads of differing specific gravity in a glass tube with a rubber bulb on top or a complex electronic device that determines specific gravity through measurement of other characteristics. A battery hygrometer uses floating beads to determine the charge of a lead acid battery because the specific gravity of the electrolyte will vary for a given state of charge.
