You are correctly registered as a Business Seller so it is up to you to decide what services you offer. For example the battery, why give a buyer the option of selecting a service that should not be used?
Are you not able to mark as dispatched yourself, that avoids any question of Late Dispatch, late delivery is beyond your control, but I have always assumed that ebay would only pick this up from buyers marking in the DSRs, rather than from tracked delivery where there are so many possibilities for things to go wrong, ranging up to never even showing as delivered.
