Answer

The two sentences are correct. And your interpretation is incorrect.

1. How long is necessary?
I don't know, but it lasts longer than that (that = is necessary).

2. Standard rules of omitting "is". Technically, exactly the same sentence.

Answer

It lasts for longer than necessary 
It lasts for longer than it is necessary 
I think

Answer

I guess it sounds better if u say: It lasts longer than necessary.
