It measures specific gravity in the 1.10–1.30 range to help you assess the battery's charge and overall electrolyte condition.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What is the battery hydrometer made of, and is it durable?\u003c\/h4\u003e\n\u003cp\u003eA: The hydrometer is constructed from high-quality glass and rubber. The glass barrel allows for clear, easy-to-read measurements, while the rubber suction bulb and seals are resistant to the corrosive electrolyte fluid found in lead-acid batteries, making it a durable and reliable tool for regular use.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How do I read the results on this electric density meter?\u003c\/h4\u003e\n\u003cp\u003eA: Once you draw electrolyte fluid into the glass chamber using the rubber suction bulb, a small float inside the barrel will rise to a level corresponding to the fluid's specific gravity. Read the value where the surface of the fluid meets the graduated scale on the float. A reading closer to 1.28–1.30 typically indicates a fully charged cell, while lower readings may suggest the battery needs charging or servicing.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What type of batteries can I test with this battery hydrometer density meter?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"This hydrometer is designed for use with flooded lead-acid batteries, including standard automotive car batteries, marine batteries, and deep-cycle batteries that use liquid electrolyte.
