Specification:Material: ABS, PC, Electric BoardQuantity: 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: Practical, Portable, ConvenientFit Type: Universal FitWhy do you need this product?-Featuring a compact and lightweight design, the voltmeter is easy to carry and store.-Simply plug it into the cigarette lighter socket to monitor battery voltage in real time.-This voltmeter helps you monitor battery status, protect the circuit system, and extend the service time of both the motor and battery.Note:-When the vehicle is powered but not running, the battery voltage should read between 12.2–12.8V. If the voltage drops below 11.6V, the driver should turn off electrical equipment and start the engine.-After the engine is started, the alternator voltage should remain between 13.4–14.8V. A reading below 13.4V indicates insufficient charging, requiring inspection of the alternator belt and possible abnormal loads.-If the alternator voltage exceeds 14.8V, excessive output may damage the battery and electrical components. The vehicle owner should inspect the voltage regulator.-A voltage below 10V in the battery may prevent the engine from starting.
