It is \u003cem\u003enot\u003c\/em\u003e suitable for sealed AGM, gel-cell, or lithium-ion batteries, as those do not have accessible liquid electrolyte.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What electrolyte density reading indicates a fully charged battery?\u003c\/h4\u003e\n\u003cp\u003eA: A fully charged lead-acid battery typically shows an electrolyte density of approximately \u003cstrong\u003e1.265–1.280 g\/mL\u003c\/strong\u003e. A reading below 1.20 generally indicates the battery is significantly discharged and may need charging or replacement.

Simply insert the nozzle tip into an open battery cell, squeeze the rubber bulb, then slowly release it to draw electrolyte up into the glass tube. The internal float will rise to a level corresponding to the fluid's density — read the number at the liquid surface line. Always wear gloves and eye protection when working with battery acid.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How do I clean the hydrometer after use?\u003c\/h4\u003e\n\u003cp\u003eA: After each use, draw in a small amount of clean distilled water, then expel it to flush out any remaining acid. Repeat a couple of times.
