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.
A sealed lead-acid battery, such as a valve-regulated lead-acid (VRLA) or gel cell battery, cannot have a hydrometer test done. This is because these batteries are sealed and do not allow for the removal of electrolyte to measure specific gravity, which is what a hydrometer test requires. Additionally, attempting to open these batteries can damage them and pose safety risks.
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
