Here is a link to [url=http://www.yuasabatteries.com/faqs.php?action=1&id=30]Yuasa instructions for testing a battery and charging system with a voltmeter.
As per instructions, wait at least an hour after charging to perform the tests.
Another load test that I do is to connect the voltmeter and turn on the ignition (lights on) and monitor the voltage for a minute. The voltage should remain steady. If it drops rapidly and continues to drop, then the battery is bad.
