If you check the image attached captured when I was scanning a Honda civic 2008 with my car scanner Autel Mk808TS while its ignition was on, you will see the voltage of the car's battery to be 12.22V. That implies that the battery of the car is in good condition.
If you own or know about a car or vehicle, you will agree with me that battery and alternator are essential in it. The battery supplies power to many things in a car or vehicle while the alternator charges the battery. There are some instances when ones car or vehicle will not start because the battery is low, and we keep wondering if there is a parasitic drain, if the battery is wrong or if the alternator is not working or has gone bad.
Many people like me, having car scanners like the Launch CRP129E used in the video below, don't know that they could check the status or condition of their car's battery and alternator.

For emphasis purposes, whenever you check the status using a car scanner like Launch CRP 129E, which has the features, it will show the battery's voltage(should be around 12v) if the car is on the ignition. In contrast, it will show the voltage(should be around 14.5v) of the alternator if the car's engine is running.
GreaterFuture: I did unlimited internet for two people here, it's been serving them well. Price is a lot cheaper, compared to this. Some twist to it, But it's okay.
