Laptop battery and adapter voltage question

Hi

Recently my adapter for my notebook broke. This is not the first time this happened to me (not same notebook though) so I already have a multi adapter. This multi adapater can be set to a voltage from 15V to 21V.

Now the question
The notebook is rated to 19V => 2,15A so I should be able to use the adapter for this notebook but what I'm confused about is the battery. It says 11,1V on the back of the battery so I'm a bit concerned how the battery will respond on the new adapter. Any ideas?
