Be Descriptive
Even if you do not use the battlemaps for combat, their amazing detail will assist you in corridor descriptions. Looking at the map while describing the hallway to the players becomes easier than read plain text. You could look at the preview map of the Hallway of the Statues and say:
"As you walk down the red-lighted hallway, you can see many statues looking at you; their grim eyes seems to follow every single step you make. The floor is made of huge red marble slabs and reflects the light of the torchlights on the walls..."

Build Your Own Dungeon
You can assemble a dungeon using the battlemaps, connecting them with dark hallways and dangerous corridors and finally fill them with hideous critters of your choice. The players will enjoy the battle in your custom built dungeon. More of these supplements exist, and in no time you will be able to build any dungeon you desire.
