It's a statement which gives the fact. No any other information about.
He wrote a lot of books. He's probably dead.
He has written a lot of books till now. He still write books.
Where has he lived till now?
He has lived in Bangkok.
Now I think I shouldn't have said this in red.
There must be a context which precedes the sentence He wrote a lot of books.
I have known him.
He died two years ago.
He had written a lot of books.
I think that He wrote a lot of books is also possible in case of narrating I mean using more than one sentence.
At this moment He has written a lot of books. doesn't mean for me that he is still writing books.
I actually know nothing about whether he is still writing books or not.
It might be concluded from the sentence He has been writing a lot of books recently that he will continue writing books for some time.
