Specification:Material: ABS, PC, Electric BoardQuantity: 2 PCSColor: BlackWeight: 0.11 lbSize: 0.18×1.57×2.81 inchesMeasuring Range: 6-30 VWorking Voltage: 12-24 VOperating Temperature: -20 to 80°CFeature: Practical, Accurate, ConvenientFit Type: Universal FitWarm Tips:-The battery voltage should read 12.2–12.8V when the vehicle is powered on but not started. If it drops below 11.6V, the driver should turn off electrical devices and start the engine promptly.-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 rises above 14.8V, it may cause excessive output that damages the battery and electrical equipment. In this case, the vehicle owner should check the voltage regulator.-A voltage below 10V in the battery may prevent the engine from starting.
