It measures the specific gravity of the electrolyte solution (sulfuric acid and water mixture) to indicate the battery's state of charge. It is not suitable for sealed AGM, gel, or lithium batteries.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How do I use the battery hydrometer?\u003c\/h4\u003e\n\u003cp\u003eA: Remove the battery cell cap to access the electrolyte. Insert the hydrometer tip into the cell, squeeze and release the rubber bulb to draw in enough electrolyte for the float to rise freely. Read the specific gravity value at the float's waterline. A reading of around 1.265–1.285 typically indicates a fully charged cell, while readings below 1.200 may indicate a discharged or weakened cell.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is the hydrometer accurate enough for professional use?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. With an accuracy of ±0.005 across the 1.10–1.30 measuring range, this hydrometer is suitable for both DIY home mechanics and professional automotive technicians who need a quick and reliable electrolyte density check without expensive equipment.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Does it come with batteries or any accessories?\u003c\/h4\u003e\n\u003cp\u003eA: No batteries are required — this is a purely mechanical float-type instrument. The package includes one battery hydrometer density meter.
