No, most of the time TDE hardware librairies should be okay to fetch battery infos by itself.

You should be able to find tdepowersave in the K menu (use the search box), or start it in konsole. Everything you need will be available in tdepowersave.

Or in some extreme cases you can rely on the blinking battery led on your laptop to see when it's time to turn it off.
