Note for assessing the battery charge state by measuring its voltage
In order to reliably determine the charge state of a battery by measuring its voltage, the battery must be in a non-operating state. It doesn't matter if you are using a simple multimeter or state-of-the-art sensor technology.
If the battery was charged shortly before the measurement, other voltage values are present in the battery, which no longer reflect the actual charge state of the battery.
This means that the battery should not be charged for at least three hours before measuring its values.
