The battery serves as a ballast for the converter. Like a voltage regulator it helps limit the converters output to 13-ish volts. Without the battery you are tempting fate with voltages over 15v and most 12v items allow for 10.5- 15.0 operation.
Agree. The converter depends upon the battery as an integral component of the designed circuit to filter the ripple DC output of the converter. That's a fact.
This is very much true for some converters, and not true for others. Most modern converters that are based on switching power supplies will happily and properly run without a battery connected. Many older resonant converters will not operate acceptably. The literature for the converter should give the details.
In the case of an unknown converter, the safest option is of course to not run it without a battery.
