A healthy 12-volt battery should maintain a voltage range from 9.6 - 10.5+ volts under the load for 30 seconds straight. We don''t expect you to run the starter for 30 seconds for starting batteries, so if you see the voltage meter drop within the voltage range and it sounded like a good strong start, then you probably just had a discharged battery.
The key difference with a real battery is that the voltage across its real terminals depends on what is connected to the battery. In the example above, the battery has a voltage of (6text{V}) across its (real) terminals when nothing is connected, but the voltage drops to (4text{V}) when a (2Omega) resistor is connected.
