Specification:Material: ABS, PC, Electric BoardQuantity: 1/ 2 PCSColor: BlackWeight: 0.11 lbSize: 2.82 × 1.57 × 1.18 inchesMeasuring Range: 6-30 VWorking Voltage: 12-24 VOperating Temperature: -20 to 80 °CFeature: Precise, Convenient, DurableFit Type: Universal FitWhy do you need this car LED cigarette lighter voltmeter?-With a compact and lightweight design, this cigarette lighter voltmeter takes up minimal space inside your vehicle.-It continuously monitors automotive battery voltage, enabling you to detect battery issues for timely repair or replacement.-This voltmeter features exceptional weather resistance, withstanding high temperatures inside vehicles without cracking to ensure reliable performance.Notes:-When the vehicle is powered but not running, the battery voltage should be 12.2–12.8V. If it drops below 11.6V, turn off all electronics immediately and start the engine to recharge.-After the engine is started, the alternator voltage should stay within 13.4–14.8V. A reading below 13.4V means insufficient charging—check the alternator belt and look for abnormal electrical loads.-If alternator voltage exceeds 14.8V, it may damage the battery and on-board electronics. Inspect the alternator voltage regulator to fix this.-A battery voltage below 10V may prevent the engine from starting entirely.
