[Solved] What's a normal charge of an alternator?
Hey uncle Scotty! What's a normal alternator charging volts when checking the battery? I've seen ChrisFix say 14.2 to 14.6 or 8 I think. Because mine with all accessories on, it's 13.6v when checking through a digital voltmeter on the battery terminals.
For a functioning alternator, a usual range is 13.5V to 14.5V, ideally 13.8V to 14.2V. But with accessories running it will be a little lower than that of course.
Scotty answers your question @ 6:50. I agree with his conclusion, however he got an important fact wrong.
Nominal voltage of a lead-acid electrochemical cell is exactly 2.10V. So nominal voltage of a car battery with 6 cells would be 12.6V, not 13.2V as stated in the video. I have never seen a battery at rest measure more than 12.8V.
