  • Tests non-sealed battery acid concentration in seconds
  • Professional-grade build ensures reliable repeat measurements
  • Brand-new Mighty Max Battery hydrometer model 3464447

Purpose and user

The Mighty Max Battery MAX3464447 is a hydrometer tester built to measure specific gravity in non-sealed lead-acid batteries. It gives a quick, colour-coded reading of electrolyte concentration so you can judge cell condition in seconds.

Who it suits and who should look elsewhere

Technicians and hobbyists who maintain flooded batteries in automotive, marine or backup-power roles will find the float scale easy to read. Buyers needing to check sealed AGM, gel or lithium cells cannot use this instrument because it requires access to liquid electrolyte.

Checks before ordering

Confirm that the batteries you intend to test have removable vent caps so the nozzle can draw fluid. Verify that you are prepared to handle sulphuric acid and follow the California Proposition 65 warnings supplied with the product.

Questions about this item

What type of battery does the MAX3464447 hydrometer require for testing?

The tester is designed to check the concentration of battery acid in non-sealed, flooded lead-acid batteries with removable cell caps.

Can I use this hydrometer on my sealed AGM or gel batteries?

No, the instrument only works on non-sealed batteries where electrolyte can be drawn into the float chamber for a specific gravity reading.

How do I confirm the hydrometer is giving accurate specific gravity readings after I draw the electrolyte?

The precision graduated float settles at a level shown by the colour-coded scale, indicating the cell's state of charge and condition in seconds.
