Why do you need such one LED digital voltmeter?
-With the increasing richness of vehicle products, the installation of speakers, refrigerators, vehicle vacuuming, vehicle inflating, vehicle lighting, and electricity for field trips have become people's daily routine.
-People are always worried while using electricity that the battery will lose power and won't start the car.
-Now you don't have to worry about it all the time, with a voltmeter you can always digitally display the fluctuation of your car's voltage. Let you have no worries, have fun.
Some small suggestions about daily use:
-When the car is powered but not started, it is showing the voltage of the battery. The normal value is 12.2-12.8V, if it's below 11.6V that you should pay attention to as soon as possible to turn off the car electrical appliances and immediately start the engine charging. If the value is lower than 10V, you may can't start the car.
-When the car is started, it is showing the generator's voltage. The normal value is 13.4-14.8V, if its value is lower than 13.4V that you can't charge the battery. At this time, you should check the generator belt and the abnormal load of electrical appliances. If it's higher than 14.8V, it is too much power generation. That will damage the battery and the electrical equipment on the car, that you need to check the generator voltage regulator.
