Battery Hydrometer for Lead-Acid Testing

The Mighty Max Battery MAX3464444 is a professional hydrometer designed to measure specific gravity in non-sealed lead-acid batteries. It provides accurate indications of battery charge status and overall cell condition in seconds. This tool is for technicians and vehicle owners who maintain flooded batteries and need reliable fluid analysis.

Precision Graduated Float with Colour Coding

The single specification that decides suitability is the precision graduated float with colour-coded scale for specific gravity readings. It tests battery acid concentration directly and delivers immediate results without power or calibration. Buyers who need to test sealed AGM, gel or lithium batteries cannot use this hydrometer.

Manual Operation with Chemical Safety Notice

The tester draws a small fluid sample into its transparent body where the float rises to indicate charge level. Operation is manual, silent and requires no external power source during normal use. California Proposition 65 warnings apply because the product contains chemicals known to cause cancer and reproductive harm.

Questions about this item

What does the specific gravity float reading tell me about my battery?

The precision graduated float shows the acid concentration in each cell, letting you see the charge level and overall condition of non-sealed batteries in seconds.

Which battery types can this hydrometer test?

It is designed for non-sealed, flooded lead-acid batteries where you can access the electrolyte; sealed or maintenance-free batteries cannot be tested with this tool.

What do I need to reach the electrolyte for testing?

You need removable vent caps on the battery so the hydrometer nozzle can draw fluid into the barrel for a reading.
