How do I hide the battery icon when no battery is present?

^^ is my current config

However, when i'm connected to wifi, and on my desktop (which has no battery) I get a 1px wide line for battery.

There appears to be no css for when no battery is detected, is there a workaround I could use to hide the battery module completely in such cases?
