What is the issue? (required)
I use at home battery maintain 70 to limit the charging to 70% but I've observed that the "Battery" app resets the charging limit to 80% from time to time without input from the user.
100% reproducible when the indicator is closed(Quit option) and then opened again.

What exactly did you do to produce the issue? (required)
Steps to reproduce the behavior:

1. Open battery app/indicator
2. From Terminal, execute: battery maintain 70
3. Check the battery indicator for the change to 70%, after which you Quit the app
4. Open the battery app/indicator again and see that it ignores user settings and sets the limit back to 80%.

Expected behavior (required)
The battery indicator should not reset the user settings, it should query the current limits and display that value instead, without changing it.
If no value was set, it should set it to 80%(first boot/init).
