Hi, I’d like to know if and how to measure the state of charge of a car battery with the multimeter correctly. I just want to be able to judge whether you should charge the battery or not. I’ve already read something about it, but the discussions often go in the direction of “you can’t measure everything with it either”. Sure, but I’m only talking about the significance of whether the thing is “empty” or not and when it’s empty. You can just hold and measure the multimeter, but d The point is, my uncle got a new battery today and then immediately hung his cheap little “battery meter” on it (I don’t trust the piece of shit). The thing showed that the battery was half charged. He wanted to charge immediately, because half charged is also shown orange which means “attention!”. The “measuring device” tells me a But I kept the multimeter to it before and the thing had 12.69 volts. From my point of view, the state of charge was ok? But is the question how to interpret the 12.69 volts from the multimeter or the result of the “measuring device” if the battery is not connected in the car? I had found “direct values” somewhere in the network too. 1.7 to 1.8 V stand for fully charged. That was then also n but I can’t find the page anymore. I don’t know how serious you can take such a thing? I suppose I have a car, the battery is connected. Do you just keep the multimeter there and can then interpret the value according to any specifications? Play as in the end still things like life time (car has just been moved or not), weather, temperature or type of car/battery type a role. If the battery is just charged n, then you should not measure. So you would have to wait a while (not exactly defined) after a car ride? mfg
