Batteries do not have drivers. As mentioned in the comments you might want to try installing TLP.

sudo add-apt-repository ppa:linrunner/tlp
sudo apt-get update
sudo apt-get install tlp tlp-rdw

TLP will automatically start upon system startup, but to avoid having to restart the system to get it running for the first time, you can start it (required only the first time) using the following command:

sudo tlp start

I have a laptop too, power hungry i7 and 17" screen and get 3-4 hours battery life using TLP. Source:

You will also want to make sure you have the correct drivers installed. Go to settings >> Software & Updates in the last tab:
