Correct understood. Put a charger on it and is at 100%
That means virtually nothing. A worn out battery typically WILL show fully charged like that but then not be able to produce any, or enough, useful current.
You need a voltmeter.....to check the battery with the ignition ON.
And as said, sometimes connections that look clean and tight really aren't. In that case, the voltage on the actual battery posts would be different from the voltage on the connectors attached to them.
