GLASS BATTERY HYDROMETER

  • Condition: NEW
  • Color Coded Float For Easy Reading
  • SPECIFIC GRAVITY OF ELECTROLYTE
  • Test Your Own Battery In Seconds

Forget about false starts with this handy little hydrometer. The battery hydrometer checks the charge of a battery by measuring the density of the electrolyte in the cells.

Operation

  • 1. Remove vent caps or covers from the battery cells.
  • 2. Squeeze the hydrometer bulb and insert the pickup tube into the cell closest to the battery’s positive (+) terminal.
  • 3. Slowly release the bulb to draw in only enough electrolyte to cause the float to rise. Do not remove the tube from the cell.
  • 4. Read the specific gravity indicated on the float. Be sure the float is drifting free, not in contact with the sides of top of the barrel. Bend down to read the hydrometer at eye level. Disregard the slight curvature of liquid on the float.
  • 5. Record your readings and repeat the procedure for the remaining cells.

Range:

  • Red: 1.100-1.205: Battery Cell is in discharged condition
  • White: 1.205-1.260: Battery cell needs attention
  • Green: Battery Cell is in Good Condition
