Description
Product Overview
The AUTOLUMEN Battery Hydrometer is a precision‑engineered battery tester designed for automotive applications. Housed in a durable plastic casing, the device features a dynamic suction mechanism that draws electrolyte from the cell for an accurate specific gravity reading. The built‑in scale ranges from 1.275 to 1.300, covering the full spectrum of battery health indicators. Compatible with 6V, 12V and 24V lead‑acid batteries, it serves cars, trucks, motorcycles, golf carts and other battery‑powered equipment. Package dimensions are 9.96 x 4.53 x 1.61 inches and it weighs just 3.53 ounces, making it portable for field use.
Usage
To use, remove the battery cell caps, insert the hydrometer, draw the electrolyte into the chamber, and read the scale. The process takes less than a minute per cell, allowing quick diagnostics during routine maintenance, pre‑purchase inspections, or after a vehicle has been sitting idle. Its clear markings work in bright daylight or low‑light garage environments, making it suitable for professional mechanics, fleet managers and hobbyists alike.

FAQ
Can this hydrometer test AGM or gel batteries?
Yes, it can measure the electrolyte specific gravity in AGM and gel sealed batteries, though the reading may be slightly lower due to the battery design.
Do I need any special tools to use the hydrometer?
No additional tools are required; the device includes a suction tube and a built‑in scale, making it ready to use straight out of the box.
How often should I test my vehicle’s battery?
For optimal performance, test the battery at least twice a year—before summer heat and winter cold—and after any deep discharge events.
Is the hydrometer safe for use in cold climates?
The plastic casing is rated for temperatures down to -20°C (‑4°F), and the suction mechanism functions reliably in cold conditions.
What does a reading of 1.275 indicate?
A specific gravity of 1.275 suggests a partially discharged battery that may need recharging or further inspection.
