Hydrometer Tester for Non-Sealed Batteries

The Mighty Max Battery MAX3464429 hydrometer tester is built for owners of golf carts and deep-cycle batteries who need to check individual cell condition. It measures the specific gravity of battery acid to reveal charge level and overall health in seconds.

Fits Routine Maintenance Without Power

The tester works directly on accessible cells of flooded lead-acid packs, requiring no external power source or vehicle disassembly. It frees technicians from guesswork by showing which cells are lagging before a full bank failure occurs.

Passive Operation With Chemical Warning

The glass float and rubber bulb draw fluid by hand pressure, so there is no electrical draw, fan noise or heat generated during use. California Proposition 65 notices apply because the instrument contacts battery acid that contains listed chemicals.

Questions about this item

How long does the float take to stabilise when testing a deeply discharged cell?

The precision graduated specific gravity float settles in seconds, giving an immediate colour-coded reading of the battery fluid condition.

Does the glass tube or rubber bulb become too hot to handle during back-to-back tests on a golf-cart bank?

The hydrometer has no heating element and draws no power, so it stays at ambient temperature even after continuous use.

What type of battery must I already have for this tester to work?

It only works with non-sealed, flooded lead-acid batteries that allow access to the electrolyte for specific-gravity sampling.
