Batch processing applies the same steps to many files at once, which saves time on repetitive jobs such as export, level and format changes. Test the settings on one file first, run the batch on a copy, and review a sample of the outputs before you publish any of them.
Batch processing is useful when you have many files that need the same change, such as exporting a series of episodes at one loudness, or converting a folder of recordings to one format. It saves hours. The risk is that a wrong setting is applied to every file, and nobody notices until the damage is done. Control is the difference between a timesaver and a mistake.
Batch steps suit repetitive, predictable changes: format conversion, a fixed gain change, a standard export. They do not suit creative decisions, such as cutting the best take or matching a voice. Keep the editing manual, and batch the final steps.
Run the settings on a single, typical file, and listen to the output. Check the level, the peaks and the quality. Only when that file is right should you move on to the batch. Testing takes minutes and prevents hours of rework.
Run the batch on copies of the files, not the originals. Keep the raw recordings untouched, so you can run the batch again with different settings. This is the same discipline as the backup routine.
Do not trust the batch blindly. Listen to the first file, a file from the middle and the last file. Check the loudness of the export with the LUFS meter, and look for clipping or silence where there should be speech.
Use a naming pattern that shows the batch, such as a suffix for the export settings. Clear names make it easy to find the right files and to tell the batches apart later.
Batch processing can hide problems across many files, and some tools behave differently with unusual input. Check the outputs, keep the originals, and be ready to run the job again if a setting turns out to be wrong.

Usually not. Creative editing needs to be done by hand, file by file.
Listen to a sample of outputs and check their loudness, peaks and content.
Re-run the batch on the copies, with the correct setting, since you kept the originals.
