But isn't the point not so much the frequency of battles but in the very next episode (assuming it wasn't a multi-parter) the ship would look brand new? The Captain's log is a great way to address issues.
Cpatain's Log, whilst we have managed to repair the hull damage from the Battle with the <insert name>, Several decks still remain out of use.
Captain's Log, Engineering reports the have come up with a way which will allow us to replenish or Phton Torpedeo reserves.
etc...
All it takes up is a few seconds of screen time, and has minimal impact on the actual episode. In a visual story telling medium you should ideally show the audiance and falling that at the very least tell the audiance. But to do neither is sloppy writting TNG and TOS could get away with it in part as they could easily put into a Starfleet Repair Yard in between episodes for repair and new crew. VOY cdertainly didn't have the option for the later as for the former sure they could perhaps put in at a repair facility but they wouldn't have access to Starfleet parts. And yes the replicator would work for certain parts but as we are told they have no way to replace their Photon torpdeos, it means the replicator has limits as to what they can replicate.
