SAY GOODBYE TO GUESSWORK AND GET PRECISE DATAProduct AttributesSize: 11.02*2.83*1.90 inchWeight: 2.79 ozColor: BlackMaterial: Silicone + PSPackaging: 1x Battery Hydrometer TesterNote1. The black plastic buoy must be aligned vertically with the centerline when measuring2. Suck in battery electrolyte until it is above the lowest line of the horizontal electrolyte levelProduct FeaturePremium Material: The shell is made of impact-resistant PS material, which is wear-resistant and not easy to crackHigh-Precision Inspection: Accurately present the electrolyte density, quickly determine whether the battery is healthy or notTransparency: Highly transparent material for clear observation of buoys and pointer indicationsDensity Standards1.275-1.300: Battery in health condition, may continue to be usedLess than 1.250: Battery in poor condition and need to be replaced in a timely manner

• Color-coded: The battery hydrometer features a color-coded density scale (gray, orange, and blue zones). Readings below 1.25 are indicated by a warning gray/orange display, while the optimal range of 1.275–1.300 is clearly shown in blue, enabling instant assessment of battery condition
• Durable and Rugged: The casing is crafted from highly transparent, impact-resistant material, offering excellent light transmission for easy monitoring of the float and electrolyte levels. It is also drop-resistant and abrasion-resistant, and will not crack or deform from accidental drops during daily use
• Wide Compatibility: Whether it's your sedan, truck, motorcycle or golf cart—as long as they use common 6V, 12V, or 24V batteries—this car battery tester will come in handy. It's your reliable assistant for managing the health of batteries across multiple vehicles
• Simple Operation: Insert the straw into the battery's electrolyte, gently squeeze and release the bulb at the top to draw in the electrolyte. Keep the battery hydrometer tester upright, align your line of sight with the liquid surface, and read the measurement directly
• Compact & Portable: The battery tester automotive is small and lightweight, easily fitting into car glove compartments or repair toolboxes without taking up excessive space. Ideal for emergency use during long-distance road trips or outdoor work
