Enabling batches allows you to group / choose what to post.  Disable the option to Track Deleted Journals to stop having to post blanks.

Wow! Thank you for answering my question so quickly! 

When Enabling batches, what impact does this have on anything else? Or is this just another reference that Sage will give me when searching for these transactions? I not only have the option to search it by Entry number, I can now search by batch number if needed? or will this make another connection elsewhere? (I'm not even sure if my question makes sense at this point, apologies)

Turn it on in a test company and see for yourself.  Basically it just adds a screen before you can work with the entries.  When posting, you can select individual batches (or all) for processing.

As Kevin has already stated, batches are mostly used to separate entries.  Separate batches allow you to update one or more batches at a time.  Without batches, all entries are updated.

You can also add the batch number to screen below, using Custom Office:
