I’ve been behind in carrying out my testing. Need to get back at it. I did get a new toy to try. $39.99-7% Amazon discount with SAE plugs, a nice LCD with temperature and voltage data, and a temperature sensor.
Off by 0.3V? Sorry, looks like cheap Amazon junk as usual to me...
that could be a set point?
I'd say maybe that's what it is outputting, but you should be measuring the same then, weird...I think @Jetronic is onto something. That or it’s self calibrated.
I have run it a few times. Sometimes way off. Sometimes about spot on.
Don’t have a photo of it spot in, but tonight I went to look at it and it was matching exactly. Weird.
Given the accuracy specification of your multimeter a displayed reading of 12.41 VDC could be anywhere from 12.32V to 12.49V actual. Now consider that looking at a state of charge table for car batteries, 12.32V is 70% charged and 12.50 volts is 90%. You’re using a piece of test equipment that, when operating within spec, cannot distinguish between them.
I’ve noticed it has gotten closer. Here it is not outputting, and it is very close. Far closer than the consistent 0.3V I saw when I first had it. It is also flagging the battery as bad. Not sure why. It may well be not that great. But I don’t know that it’s condemnable. Probably should do a real resistive load test on it...I'd say maybe that's what it is outputting, but you should be measuring the same then, weird...
You must have very sharp fingernails, or pressed it hard!After gathering info from various reviews I bought a NOCO 10. Be careful pushing the mode button on your NOCO! Less than 2 months and the button has failed. A simple label that sticks on, but NOCO cannot supply one. To get it resolved, actually replaced, I have to send it to them. No parts, no repairs. No more IP65 water proofing wither.

Actually was using it in 15-20°F ambient temp trying to get it to change modes and felt it crack. Good stuff!You must have very sharp fingernails, or pressed it hard!
Takes about 20 mins before the 3 amp charger from Walmart says charge complete.
