Is there a way to check a camera battery WITHOUT putting it in the camera or charger?

Generally a voltmeter will not provide you with accurate results because you need to check the battery under a load and a voltmeter alone will not do that.

Actually, they are called volt-ohm-meters, or VOMs.

There are voltmeters made for just voltage measurement. The VOM's are not popular any more. Now they call them Multimeters.

The only voltage only meters I have seen are made to mount on panels. The portable ones were VOMs or multimeters. But I haven't seen it all.

My father had VOMs, volt-ohm-meters. Today, in keeping up with the times, I use Multi Meters.

And what is the difference, other than the name? I assume they both have an ammeter function as well.

Neither will give you an accurate idea of battery condition, without putting it under load.
To check a battery without putting it under load, you need a capacitance meter and the manufacturer's test specs.
Due to the ridiculously high costs of capacitance meters, it is just not worth it for camera batteries.

Basically it's just the name but a VOM typically means an analog meter and multimeter is a digital one.

A capacitance meter? I’m thinking you mean capacity, not capacitance.
If you want to check a typical 9.6v battery with a DVM (that’s a digital VOM), just buy a 100 ohm 2 watt carbon resistor (cheap) and put it in parallel with the meter leads. That will draw ~100 ma. and dissipate just under a watt, or you can use a 50 ohm 2W which will draw almost 200 ma and dissipate about 2W. Different cameras will draw different amounts of current also depending on whether the WiFi/Bluetooth and LCD panel are on, but 100-200 ma should be a decent representative load.

Volt-Ohm-Milliamp meter...
A VOM IS a multi-meter. Synonyms.
