I don't have access to a Windows box, but something like:

SETLOCAL EnableExtensions EnableDelayedExpansion
FOR %%I IN (batchengine-*.era) DO (
    SET NAME=%%~nI
    RENAME "%%I" "!NAME:~28!%%~xI"
)
ENDLOCAL

Type FOR /?, SET /?, and SETLOCAL /? in the console for all of the details on the syntax. Hopefully I have something pretty close. You need to introduce new variables within the loop so that you can access the extended syntax to subscript - e.g., !NAME:~28! selects the substring starting at character 28. The !NAME! is a delayed expansion reference. The need for this is explained in one of the command synopsis pages.
