How to clean up old entities

I want to know the best way to clean up old entities. I am on the latest version, .95.4

I use for example the batter package here:

But I changed trackers and old battery entities are still showing up.

I had pairing issues with some ZigBee devices, so I repaired and I cannot name the new entities correctly as the name is take, but it’s not in the unused entities list.

I see them in a file in the .storage folder and figure I can go delete in there but wanted to check if another way to see listed entities, not being used or working or something. I don’t even know what all to delete, it’s take some time to get things right over the last year

I believe for the battery notification there is an option to clear the mqtt topic. Perhaps read its topic how to use that.
