to check how much electrolyte is present in the battery
a hydrometer checks the state of battery charge using specific gravity.
To check the specific gravity of a battery, you will need a hydrometer. Remove the battery caps and draw some electrolyte into the hydrometer. Compare the reading with a chart to determine the specific gravity, which will indicate the state of charge of the battery.
Hydrometer.
A hydrometer is commonly used to test the specific gravity of a forklift battery. This device measures the density of the electrolyte in the battery, which can provide information about the state of charge and health of the battery.
With a hydrometer which you can buy at any auto parts store.
a Hydrometer is used to measure the density of a solution, by the use of a scaled float. typically it is used for battery acid.

It is an instrument to measure or gauge density of gravity.
It is called a hydrometer.Also, density equals mass divided by volume.See the Related Questions to the left for more information about hydrometer and density.yup
For checking specific gravities of liquids such as battery acid and antifreeze.
